I purchased Alcatel Flash 2 about 8 months ago from Lazada and everything was fine up to 1 month ago. The phone started giving issues as below
b) After being charged to 100%, and after using for a while, the screen will pop out with 'Your battery temperature is too hot. Dismiss or Snooze'' and yes after that suddenly the phone will switch off by itself, despite battery power around 70%. And the battery behind would feel warm/hot. The phone will then refuse to be switched on again immediately after and only will be switched on again maybe after two hours, at this point, the battery would show 0% and needs to be recharged.
b) I went to the local official service centre for repair and after 2 days I got the phone back, and they informed me that the mother board was giving problems. The battery was fine. After being repaired the phone was good for 10 days and then the same problem discussed above started again.
c) I went back again to the same service centre and after 2 days, I got my phone again, in which they claimed that everything is alright.
d) Yet my phone is still giving the same problem despite going to the service centre twice. The phone switches off by itself at anywhere from 50-70% battery power and it refuses to restart again, only restarts after two hours. After restarting sometimes the battery shows its 0% and then the phone goes off again or sometimes at the same percentage before it switched off the same time.
Can the moderators and staff tell me what to do as I don't want to go to the same service centre and also my phone is still under warranty?
