Android 7.1.1 started coming on Sony Xperia Z5, Z3 + and Z4 smartphones at the end of June. The update has a number of improvements and new features. But some users claim that the new version of the operating system has seriously reduced the performance of their device. High heating and emergency reloads occurring regularly due to this are also reported.
It is not yet known whether Sony is preparing a patch that would fix the problem. However, you can solve it yourself. To do this, disable the Movie Creater application. After that, go to safe mode. To do this, press the power button and hold the " Restart " button. Then it remains only to restart the smartphone.
