STUCK on welcome screen & Dying batteries
i have installed a custom ROM I don't know which ROM specifically, but the ROM was 4.3
anyhow i did not feel comfortable with the rom the keyboard did not work , so I installed 4.3 stock rom through ODIN.
the stock rom did not work perfectly sometimes the device reboots itself ...and when i call the screen turns black and I can't use it until i finish the call.
I had four good batteries....
now I can't use two of them ( when I plug them in charger they make the big battery logo fully green , but they keep charging and never shows fully charged unplug message) ..when I turn the phone on its keeps rebooting and never stops .
the other two batteries shows incorrect percentage reading ,like when i charge the phone after its completely run out of battery Its instantly become 40% charged but it's actually less than 1% .
I don't know if its a hardware issue or the system capable of ruining the batteries.( all four batteries had the problem on the 4.3 stock rom) I've tried the batteries on different phone and i experienced the same issue.
i installed 4.4.2 stock rom through ODIN and i did not had the previous (non-battery) issues with it ...but today i turned the phone on and it displayed the samsung galaxy welcome screen (like if it got factory reset) !
and it displays (Unfortunately, S suggest has stopped) when i press ok it displays (Unfortunately,the process com.google.process.gapps has stopped) >ok> ( Unfortunately google play services has stopped) >ok> ( Unfortunately,the process com.android.phone has stopped) ..... and its keep doing that !
i did cache wipe and downloaded and installed other version of 4.4.2 stock rom and i experienced the same issue.
if i connect the phone to PC the it shows that the total capacity is only 107MB !!
i did not try factory reset i don't want to lose the data if it's there.
is there a way to recover the data?
how can i fix the phone?
what is it with the dying batteries?
