Hello , or can you give me advice on how to do it in your device back to the previous version ? At night, the phone actualization itself to fatal version of the android 6.0 update before .... Battery operated about 3-4 days at full load ( camera , BT , WIFI , @ , conversations and messages ) At present, the rate of decline percentage for the battery is more or less an 1 % per minute due to a fucking shit 6.0 android ... I would ask for help, function keys are in a language that does not quite understand .
Can you help me ? The phone got four days ago for the birthday , and now can serve, at most, as a paperweight ....
If someone could transcribe to step by step how to do it, I was very grateful . Even as someone would have written in Polish it's a miracle
