Phone keeps switching off tried new battery still not working
So I have this problem for a while.at the beggining my phone occasionally turned off by itself.and when I turned it off battery was in critical mode.
After I thought because was problem with battery beeing addicted ordered new battery from eBay.
the phone worked whilst on charge.then it started to die whilst on charge.
Now the phone doesn't even work whilst on charge it just dies after 15secs of beeing on and sometimes just gets on a loop trying to turn on.
I tried with new battery and it's same thing. I tried resetting the phone but he dies obviously.so I tried on safe mode the reset (volume key,power key and home key)and he just resets and when it gets on, all apps are there so that means he's not resetting nothing at all.
Now I get messages like "phone tracker suddenly stopped" or "unfortunately,com.google.android.gm has stopped"
I tried to remove power safe off.
Did reset on settings all previous app definitions.
I couldn't find anything that helps on google.and I've noticed that the original battery is like bulgy.
I'm running 4.1.2 android version and kernel version 3.0.31-742346
Original battery made in Japan assembled in china GB/T18287-2000
I don't know if this info helps but please give an answer guys because I tried lots of things and nothing seems to work.
