If you don't like to look at microcircuits, then here is a short summary of everything, which is detailed below:
1. Galaxy S7 is disassembled from the back, which means there is no risk of damaging the screen. Most service centers will undertake such work, the repair speed will be higher.
2. The back cover is very tightly glued to the metal frame. There are no rubber pads under it, and the factory double-sided adhesive tape protects the device from moisture. If you leave your smartphone under the summer sun for a long time, then due to strong overheating, the glue will gradually lose its properties.
3. Power button pusher samsung galaxy S7 looks more reliable than most other solutions. Which is great, because these buttons often break.
4. For the first time, Samsung installed a copper heat pipe inside a smartphone for cooling. The new Exynos 8890 chip is not only powerful, but also hot!
5. If the battery or other removable components fail, and you decide to change them in an unauthorized service center, then everything will go pretty quickly. But after that, the Galaxy S7 will most likely cease to be protected from water.
And now to the microchips!
How does it open?
The device opens from the back: you need to heat it and then carefully separate the back cover. There are no rubber pads here, the double-sided adhesive tape does not let water through the back panel. At the factory, it is cut out in advance according to the shape of the apparatus.
If you leave the Galaxy S7 for a long time under the bright summer sun, then the glue inside will gradually lose its protective properties. At some point, it may begin to let moisture into the case.

There are no ugly plugs on the case, but pay attention to the tray for SIM and microSD cards. It is rubberized to keep moisture out. Before you put the tray with cards into the slot, be sure to check that coarse dust does not stick to it. Otherwise, moisture may enter the case.
S7 is disassembled from the side of the back cover, and not from the side of the screen. This is good because there is no risk of damaging the expensive screen, which can cost more than 20,000 rubles.

What's under the lid?
Unusually, the flash and sensors near it are not protected by anything, they can be seen through the glass on the rear panel. This is not to say that this is bad, it’s just that Samsung closed them before. At the same time, by the way, we offer to look at these sensors under a microscope. The black element with the inscription SWB-RC203 inside the case is a “sandwich” of an NFC module and an antenna for wireless charging of a smartphone connected together.
Second layer of internals
We remove the top layer of boards and modules and make our way deeper. Here is a surprise: a copper heat-conducting tube for cooling. We have already seen such on parsing more than once Sony smartphones, a similar cooling method is also used in fresh Lumia 950, but Samsung uses such a solution for the first time.
Another interesting detail. See that little white square with crosses? If water gets inside the case, it will immediately change color to red. This is what will show specialists of official Samsung services that the device has been “drowned”.
By the way, do you remember that there are no plugs on the case at all, and all the connectors are open? The speaker is protected from moisture by a special mesh and a small rubber gasket.
At the same time, let's look at the battery: it really has 3000 mAh, although we, in general, had no doubts. The values of 4.4V and 3.85V have not changed compared to the batteries of previous Galaxy S, but the temperature mark “do not heat up more than 45 degrees” is interesting. In case of failure of the battery or other individual replaceable modules, it will be possible to change them quickly enough. After removing the back cover, of course, which immediately deprives the device of the advantage in the form of water protection.
Let's look at the details
Let's take a closer look at the speaker: there is a whole heap here, which is not very justified in terms of design. For comparison, the speaker on the left is from the iPhone, and on the right is from the S7. This is not to say that this is bad, just a different approach. The headset cable comes separately and docks to the charging cable. In past models, it is combined with a speaker module, so the solution is unusual.
Under the microscope, we also examined the power button. In the photo above - Galaxy button S7, bottom - iPhone button 5. In the case of the new Galaxy, the pusher is not just glued to the base, as is most often the case, and is implemented in the iPhone, but is additionally fixed on top.
The failure of the power button due to the destruction of the pusher is a common disease of modern smartphones. Samsung tried to make the design more reliable, which is commendable.

In the Galaxy S7, the contact groups are made removable. Obviously with the aim of simplifying the work of employees of their own service centers. In general, the device has become easier to understand, we can note a noticeable step forward compared to the S6.

Let's take a look at the microscope again. Unlike Apple, which is used to branding literally everything inside, Samsung has almost no marks on the components. But we did find something. Here, for example, is the Samsung Shannon 935 LTE modem and the Avago AFEM-9030 power amplifier. Overall, Samsung continues to strive to use as many of its own components as possible.

On this frame, two boards lie side by side: to the left of the year before last Samsung Galaxy S5 Active, to the right of the brand new Galaxy S7. They are very similar.
