Nothing lasts forever, not even an iPhone. Sometimes even such a phone can freeze and stop responding to any commands. This behavior of the smartphone is explained by 2 possible options.
Why iPhone Problems Occur
The very first, when the phone hangs while running some application that you downloaded separately from the AppStore. In this case, the best solution would be to try to minimize the phone to the round Home button in the middle, and then close the application altogether. Then you can use it again. This happens due to the fact that the application is not fully debugged in some specific moments.
If this button does not work, try to lock the phone first, if it does not work, restart it. This can be done by holding down the lock button and Home together, they must be held until the screen turns white with a black apple in the middle.
The second variant of the problem is that the phone hangs on the work of a standard application. In this case, you should try to carry out the above steps in the same order. If the problem occurs frequently enough, try connecting your phone with a USB cable to iTunes and performing the recovery procedure. All your data will remain the same, but the system will be installed the most recent and not damaged.
If the phone is not detected in iTunes, and you cannot restore it, then take it to the service center, it is likely that you have dropped it and there is a hardware problem. It can only be detected by diagnostics.
IPhone Tips
It is highly discouraged to install JailBreak on your phone - a hack to install paid applications for free. The main core of the system is being modernized as a result of this operation, and no one has carried out full debugging either, respectively, the number of brakes and glitches increases greatly.
If the phone just hangs out of the blue and does not respond to anything at all, try unscrewing the two bolts next to the charging connector and removing the back panel. There you will see a battery and one cross-head bolt, it must also be unscrewed and the ribbon cable removed. You will see that the screen goes blank. Now collect everything as it was, and try to turn on the phone. Everything should work.
