My Xperia m4 aqua(android 6.0 8gb version) automatically turns off and then turns on itself and I notice that it deletes all WiFi passwords and opened programs etc. And sometimes it just randomly shuts off while using and refuses to turn on for more than ten minutes.Why?
Everytime I start it up after turning off or just after charging it a red light lights up for three or five seconds.What does it mean?
And the last issue is that I can't free up my storage space at all I did a factory reset and it was still showing me that there is 150MB of storage remaining. What to do?
