My Galaxy s4 started dying last monday. It started by turning off sometimes, but it began to turn off all the time. Yesterday, the cellphone was dead and it wasn't charging. I left it on the charger all night and I tried turning on, but it stays 1 second in the "Galaxy s4 I9505" screen and then goes black. I can't go to the recovery menu because the cellphone won't turn on. I tried my battery on my brother's galaxy and it is working fine. I bought another battery buy the problem still persists. Any ideas on how I can solve this problem?
