today i bought a new galaxy s6 sealed from an electronics shop......the first problem i got was that when i turned it at language detect it was that it was running really slow and i had to double tap on everything for " ok" even at keyboard......i did a factory reset before i could even select the language :| ....ok so after that it worked fine but it still has problems with overheating by doing nothing and with batery life( it charged fast and the life goes down same as fast. had the same problem on a 2y old galaxy s4 and the lolipop soft solved it...).i got the phone few hours ago and it already has so many problems? any1 got any idea?
