[Q] i9505 won't turn on. Goes to docking mode when connected to usb/charger
I have a problem with an galaxy s4, i9505 version. For 2 days, the phone won't turn on if it's not plugged. When I hold the power button, it appears the chargin battery symbol for 2-3 seconds and then it turns back off. I am able to turn on the phone, only if I have a charger connected to it.
Also, when I connect the phone to the computer, it won't be recognised as a device. The phone notifies me that it has been docked... weird. this also happens with the wall charger. I tried different cables and chargers, but they're not the solution.
I also made a few hard-resets on the phone but with no success. It has original firmware, nothing custom.
Do you guys encountered this before? Is there any solution for the phone? Also the phone, randomly charges/ stops charging when plugged on the wall charger, but not the usb one. Do you think it's a hardware problem?
