Installing official TWRP Recovery on Samsung Galaxy J7. Inexpensive Samsung smartphone - Galaxy J7 Neo How to set a ringtone for a contact in the Samsung Galaxy J7 Neo

And Galaxy J7 (2017). The first one still stands out, while the other two are clearly more expensive and more advanced. However, this time it was decided to highlight the Galaxy J7 (2017).

Nowadays, the Samsung Galaxy J7 (2017) looks more like a lightweight representative of the Galaxy A line. It does not have individual features such as water resistance, the characteristics are slightly worse, but in many features the device is very close to its older brothers. For example, it is distinguished by its support for the Always On function - this is something other “Jacks” simply do not have. There was also a fingerprint scanner and so on. I won’t list everything here, otherwise you won’t read the article. So let's get started: Galaxy J7 (2017) review in detail!

Video review of Samsung Galaxy J7 (2017)

Design

So, I have in my hands the Samsung Galaxy J7 (2017), the third generation of this smartphone.

I must say that it changed from year to year. So the very first device was made entirely of plastic and was a “standard Samsung”. The second one acquired a metal edging and received aluminum sidewalls. And now the Galaxy J7 (2017) is made entirely of metal.

From the front side, the handset looks very solid, somewhat reminiscent of the same Galaxy A. It has a thinner frame around the screen, and at the same time they added fashionable 2.5D glass.

The back is really all metal, with the exception of the antenna inserts at the top and bottom. But they don’t spoil the impression; on the contrary, they are designed quite well, not at all like other smartphones. In addition, the gold color looks good, that is, we had the Galaxy J7 (2017) gold. There are also black Galaxy J7 (2017) black, blue Galaxy J7 (2017) blue and pink Galaxy J7 (2017) pink.

The Galaxy J7 (2017) has a “normal” protection standard, that is, IP54. In other words, it is protected from small splashes and dust, but it is better not to drown the phone. At the same time, the build quality is excellent, although I have not yet encountered anything different from Samsung. And now this is more than expected - the case has become non-separable!

The smartphone turned out to be moderately thin (8 mm), but weighty - 188 grams. Even for a 5.5-inch tube this is decent. Apparently, the presence of a capacious battery has an effect, although again, the thickness is small.

As a result, I can conclude about the Galaxy J7 (2017) that it looks good, feels great in the hand, the metal pleasantly cools the palm and generally leaves behind an extremely favorable impression.

Connectors and controls

In terms of connectors and buttons, the Samsung Galaxy J7 (2017) is the most classic! They even left microUSB!

There are so many elements placed above the screen that I sinfully thought that the iris scanner had somehow migrated to the Galaxy J7 (2017). In fact, there is nothing like that - there is an LED backlight for the front camera. There is a lens of this same camera, light and proximity sensors, as well as a speaker.

Below the screen you can see a mechanical Home button and two touch buttons for Back and recent applications. The touch buttons are not backlit, and in Home, as I said, a fingerprint scanner was built in - for the first time in the Galaxy J line.

Working with fingerprints is exactly the same as in all Samsung smartphones. In the Lock screen and security settings section, you can add multiple fingerprints. But before that you will need to enter a PIN code, password or graphic pattern.

Then all you have to do is scan your finger and that’s it – you can use it to unlock the phone. Moreover, you just need to touch the sensor and the screen will immediately turn on. Our short video will tell you how to work with the Samsung Galaxy J7 (2017) fingerprint scanner:

On the reverse side at the top you can see the main camera lens with LED flash and the antenna insert.

At the bottom rear there is only the antenna insert.

On the left side you can see two buttons for volume control, compartments for SIM cards and memory cards.

Samsung has stopped doing nonsense and now equips its smartphones with three full-fledged connectors: two for SIM cards and one for microSD. I note that the Galaxy J7 (2017) only supports nanoSIM - finally, even state employees are starting to switch to this standard. Card trays are removed using a paper clip or ejector. If something doesn’t work out for you, our short video will help you solve the problem:

The power button and speakerphone were placed on the right side.

All other elements are placed at the bottom: a conversational microphone, microUSB and an audio connector. As I said, Samsung has not yet switched to USB Type-C in the Galaxy J series, apparently this will happen in 2018.

The top end is empty - there is no microphone for noise reduction. There has to be some way to differentiate the Galaxy J from the Galaxy A, right?

In general, the Galaxy J7 (2017) is a classic in terms of ergonomics. All the buttons are in the usual places, the card slots are full, the microUSB is in place, the minijack for the headset is conveniently located at the bottom - what else is needed for happiness?

Buying a case or cover for the Galaxy J7 (2017) is very easy, since it is an extremely popular smartphone model. I’ll say more, I even got my hands on one case!

This silicone case for Samsung Galaxy J7 (2017) costs about 1,000 rubles. Moreover, this is a branded accessory, and even made in the main color of the smartphone.

There are also books and other covers for the Galaxy J7 (2017) - they will be easy to find.

Galaxy J7 (2017) screen

Samsung Galaxy J7 (2017) stands out significantly from its predecessors. If anyone doesn’t know, both previous generations came out with Super AMOLED screens, but their resolution was 1280x720 pixels, clearly emphasizing the mass positioning of smartphones. But the new device, which was made for 2017, has a 5.5-inch Full HD display.

Galaxy J7 (2017), thanks to its 1920x1080 resolution, provides a noticeably higher pixel density - 401 ppi versus 267 ppi for previous phones. And the Galaxy J5 (2017) does not shine against its background, offering only 282 ppi. In general, in the new generation, the older model in the line stands apart, offering the best screen.

However, the new Galaxy J7 (2017) is not only good for its screen – the smartphone also supports the Always On Display function. If anyone doesn’t know, it was first introduced together with, and later the entire Galaxy A series got it. And now the J7 (2017), which became the first of the “Jacks” with this most useful feature.

For the uninformed, I’ll tell you what it does – the time and various notifications are always shown on the screen. Or this can be replaced with a calendar or just a picture. As a result, useful information appears before your eyes, but little energy is spent on this matter, thanks to the Super AMOLED screen.

Meanwhile, the Super AMOLED matrix does its job and provides a very pleasant picture, with good colors, rich and rich. The viewing angles are wide, the image is clear and does not fade in the sun. And finally, there is support for auto-brightness adjustment - a small but extremely useful option that its predecessors did not have.

Objective measurements also speak for the Samsung device. So the brightness was measured at 296.75 cd/m2, which doesn’t seem like much, but in fact, under the sun in automatic mode, the phone can raise it noticeably higher. The black color is truly black, since we are dealing with OLED technology.

The color gamut, as expected, covers the sRGB color space, especially when the Adaptive profile is enabled. There are no problems with color rendering.

Color temperature is slightly higher than usual. In the case of the Adaptive profile it is at the level of 8000-8200K, and for the Basic profile it is much closer to the reference value of 6500K. However, Samsung devices usually have a slightly warmer picture.

The gamma curves look pretty good. Only when the Main profile is turned on does it appear in the middle, that is, the average brightness shades of the image appear lighter than they should be. But this is invisible to the eye.

As expected, the Galaxy J7 (2017) can handle dozens of touches at once.

In the screen settings you can now find a complete set: automatic brightness adjustment, selection of color profiles and even adjustment of individual color channels.

As I already said, the Galaxy J7 (2017) in terms of screen seriously stands out both from its predecessors and from other smartphones in the Galaxy J series. It has a noticeably higher resolution and has Always On support - all this is typical for devices of the Galaxy A line, which cost noticeably more.

Galaxy J7 (2017) camera

The evolution in terms of cameras in the Galaxy J7 is not very noticeable for the average person: all three generations of smartphones offer a sensor with a resolution of 13 MP. Of course, its models differ, and the Samsung Galaxy J7 (2017) has the best optics - the lens aperture was increased to f/1.7, versus f/1.9.

The control application is standard for Samsung devices. The one that the Galaxy S8 has was taken as a basis. Swiping on the right opens color filters, and on the left – available modes.

For advanced shooting, the Pro mode may be of interest, where you can adjust white balance, ISO sensitivity and exposure compensation.

The maximum resolution of 13 MP is achieved when choosing an aspect ratio of 4:3.

The camera takes decent pictures. The footage comes out clear, with good white balance. Of course, the brightness is not always well adjusted, but this is unlikely to bother many. Even in the evening something comes out tolerable.

Video is captured in Full HD resolution.

The video looks decent, also sharp, with good colors.

The front camera has been updated much more seriously - instead of 5 MP, a 13 MP sensor is now used.

From the pictures taken from the front camera of the Galaxy J7 (2017), you can clearly see that the number of megapixels does not mean their quality. The resolution is high, but everything is blurry and not very beautiful. The white balance is normal, the brightness seems to be the same, but at night the camera does not produce the best pictures.

The video from the front camera also seems to be of “high quality”, with Full HD resolution.

However, it has all the same problems for photography: it lacks sharpness.

Moreover, given the positioning of the Galaxy J7 (2017), it takes good pictures and videos. I'm talking about the main camera - everything there is more or less decent. But the front camera blurs the picture and this is not very pleasant.

Specifications Galaxy J7 (2017)

The Galaxy J lineup for 2017 includes three main devices: J3 (2017), J5 (2017) and J7 (2017). Moreover, for certain markets, the latter was multiplied by budding in two more versions: Galaxy J7 Pro and Galaxy J7 Max. The processor and screen of the first one are the same as our J7 (2017), but in the minimum version it has more memory, both RAM and flash. As for the J7 Max, it is a 5.7-inch device based on the MediaTek chipset, with a PLS display and also a decent amount of memory: 4/32 GB. It is produced only for India.

Above, I described how many changes happened with the Samsung Galaxy J7 (2017) compared to the 2016 device: screen resolution, cameras, various interesting features appeared. But what about the rest of the hardware?

Everything is generally not bad, except for the fact that the processor has not been updated in any way in a year. The same Exynos 7870 Octa with eight Cortex-A53 cores operating at 1.6 GHz is used. On the other hand, this is a decent mid-range chipset and we can’t say that it has become obsolete.

Inside it is installed, although not the newest, but still not the old Mali-T830 MP2 video card. This accelerator is also not the fastest, nor the most budget-friendly, but there are still better options. Moreover, it has only two execution units.

But they installed more RAM – 3 GB, also available for the first time for the Galaxy J line, including among the 2017 models. But there is only 16 GB of flash memory, which is logical - 32 GB was left for individual local versions and for the older Galaxy A series.

As for the rest, I will note changes in terms of communications. So Wi-Fi was extended to support the 802.11ac standard, and at the same time the battery capacity was increased by 300 mAh. For this I had to pay for it by 11 grams of increased weight and a 0.2 mm thicker “waist”.

In principle, the parameters of the Galaxy J7 (2017) look more or less normal, but at the middle class level, but nothing more. There is nothing very outstanding about them.

Performance testing

The performance difference between the Samsung Galaxy J7 (2017) and Galaxy J7 (2016) should not be serious. Let me remind you that they have the same processor, and the amount of RAM is larger in the first device.

Basemark OS obviously leans more towards expanded RAM, as the 2017 smartphone was slightly faster here.

The JetStream browser test also remained with the J7 (2017), but its advantage here is much less significant.

Graphics benchmarks agreed that the platforms of the phones are the same, and therefore there is no need to strain - the results are almost identical.

Galaxy J7 (2017) in Antutu

Now let's see how things are going in the popular Antutu system-wide test.

The result is similar to Basemark OS, although the superiority of the Galaxy J7 (2017) is less obvious. The difference will not be noticeable to the eye.

Autonomy Galaxy J7 (2017)

We will check the autonomy of the smartphone using.

What can I say, the battery life of the Galaxy J7 (2017) is good, one of the best, I would say. True, the J7 (2016) has it even better. Yes, its advantage, according to the diagram, is minimal, but there is a nuance: the battery capacity of the 2016 model is 3300 mAh, while the current one is 3600 mAh. Again, this doesn’t mean anything, it’s just that a year earlier the phone showed almost a record result, and now it’s only slightly worse.

As you can see, the energy consumption profile is completely typical. The maximum falls on 3D graphics, while everything else consumes very little battery.

In addition, the latest version of the Clean UI shell has many ways to optimize energy consumption.

Among other things, different profiles have appeared where you can configure how the phone will work. Here you can set the brightness of the screen, how the processor works, disabling wireless networks, and the like.

Overall, the Galaxy J7 (2017) is a fast smartphone with excellent battery life. A sort of workhorse that will appeal to many.

No problems are expected with games on the Galaxy J7 (2017).

• Injustice 2: excellent, the game does not slow down.

As you can see, all games work without issue. Another problem may arise with the Galaxy J7 (2017) - 16 GB of flash memory is not enough for a large number of modern games

One of the inexpensive smartphones in the galaxy line, as you know, is the J7 model. The device was released quite recently, and can without a doubt be considered a budget option. There are several factors that determine its price segment. These are characteristics, inherent features, and choice of materials. In any case, those who cannot afford flagship models will certainly find something of their own in the J7. And if you prefer this device, make sure you get the most out of it. This can be done by installing, the official assembly of which is already in the public domain.

After installing TWRP for J7, you can easily install both official and unofficial firmware. Of course, carrying out such a procedure requires great care and great responsibility. Therefore, you must first study the instructions described below, and then proceed to reinstall the recovery.

In addition to the fact that this procedure allows you to independently configure the system, it also allows you to:
open root rights;
;
install firmware and kernels yourself;
improve processor performance;
remove unnecessary applications.

Since this release of TWRP Recovery is official, it works perfectly on Galaxy J7. Flawless request processing, the absence of the slightest freezes and long-term glitches proves this. Moreover, the program is perfect even for users with minimal skills, since it has a simple and accessible internal shell.

Before introducing you to the step-by-step guide and before directly starting work on installing TWRP Recovery on the Galaxy J7, I would like to draw your attention to a number of preliminary procedures:
create a backup copy of the existing (current) firmware;
We save information that is valuable to you: photos, videos, music, work files, call logs, SMS, settings, etc.

This is done for one simple purpose: so that you can recover in case of failure. And usually something goes wrong if such articles are not read carefully enough. Well, in general, you understand what I am calling for.
Be aware right away that the firmware is not a traditional installer that is limited to one or two clicks. Here you need to really work with your hands. For those who are doing this not for the first time, it will be easier:
We begin, as in most cases, by preparing the PC. We turn off anti-virus protection on it, as this interferes with the flashing process;
Using the Kies utility, install USB drivers for the Galaxy J7 on your computer;
Of course, we put the smartphone and sync cable in front of us in advance;
Next, you need to open special features on the device. To do this, go to settings, and then to the “about phone” tab. Multiple clicks on the build number activate Developer Options;
Among other things, you need to check USB Debugging, that is, the USB debugging option (it must be enabled). To do this, go to the “developer options” in the settings;
The device's battery must have at least half its charge before starting the procedure. Premature shutdown of the J7 during installation can cost money, wasted time going to a service center and nerves;
Please note that this version is created exclusively for the Galaxy J7 (j7elte). Using the firmware for other models or brands may result in adverse consequences.

Now, in fact, the process of installing TWRP Recovery on the Samsung Galaxy J7:

I have a backup of contacts in the form of a large number of vcf files (each contact has its own vcf card). How can I combine them into one file to make it easier to import into my phone?

If the files are not stored on your PC, then transfer them there to a separate folder. Run the copy /B *.* contacts.vcf command in it and get the merged contacts.vcf file. %

The contacts.vcf file will appear in the folder next to it.

Why don't people sometimes call me when I'm on the Internet?

If your operator supports only 2G network type, and accordingly you are on a 2G network, then in this case this situation is considered normal. 3G networks already allow the user to use the Internet and receive calls at the same time, but much also depends on the operator’s equipment and the current network load.

How to glue protective glass evenly?

One of the simplest ways is to stick glass using “loops”. Lay the glass on the phone, straighten it, glue strips of tape on the glass and phone, like on the door.

I still have a file in vcf format from my old phone, in which all my subscribers from the phone book are saved. How can I use it to transfer contacts to my new phone?

There are several options, one of the simplest solutions would be: send a letter to your mailbox (to yourself) to which you attach this file. Receive the letter by phone, open the attachment in it, the system will offer to import contacts. %
Another simple option is to upload the file to your phone using a cable and a PC, then use the built-in file manager to go to the file and open it, the system will offer to import contacts (here you will need to install drivers for the PC to work with the device via a cable). %
You can also import contacts directly into your Google account via the web interface, for example on a PC, and from there synchronize with your device.

Programs and OS

Where can I download programs for Samsung Galaxy J7 for free?

How to find out the IMEI number of a phone?

How can I prevent my Android phone from automatically downloading firmware updates?

Automatic download of software updates is carried out only over Wi-Fi and only if the corresponding setting is installed on the phone. If a software update is downloaded to your phone, you can no longer install it; you can only postpone the installation, after which the phone will again ask you to install the downloaded update.

How is multitasking organized in Android?

Android applications consist of several components. There are four types of components: Activities, Services, Broadcast receivers And Content providers.
Activities represent a graphical user interface for a specific task. For example, an SMS application may have one activity for displaying a list of contacts, one for creating a message, etc. An Activity can be in one of three states:
1. Active or running – in this state it is in the foreground and interacts with the user;
2. Paused – is in the background, but visible to the user, for example, partially blocked by a new activity;
3. Stopped – completely blocked by another activity. But it still retains its state, although it is completely hidden from the user.

In the Paused and Stopped states, the activity can be unloaded from memory. A situation may arise when the user, returning to the unloaded activity, would like to see it in the state in which he left it. This is possible if you call the onSaveInstanceState() method before unloading the activity, and call the onRestoreInstanceState() method when restoring or creating the activity. In this case, it is possible to save the current (at the time of unloading) activity state. Here we can draw an analogy with the hibernation mode in PC OS.
