Since I had a warranty I return the phone to the shop where I bought it. You know the usually crap. And from there they sent it back to the constructor (I guess) anyway. They upgrade the software because they tought that it will solve the problem but it didn't.

I don't want to send the phone again and wait at least three weeks. Help me to get rid of thoses things will you ?

Initially, it worked, but after I charged it for about 20 min it stopped working. I hard reset it 2 times, checked if everything is connected properly and it still didn’t do anything. Eventually, I gave up and I accepted the fact that someone just sold me a broken one and I lost 20 bucks, but the next day I took it to my friend’s house to see if he would have any idea how to fix it. He just turned it on and it worked again, at least before I turned it off and on, then it broke. Does anyone have any idea what could be causing that and if it’s fixable? Any help would be appreciated. Cheers
