Good Morning,

i have the phone of my mother in law and it's rebooting continously when in standby. as long as the display is on, you can use the phone normal, but after locking it device starts to reboot again and again. did someone have this before?

btw: Chargng is a little bit slow, but i think it's because of the reboots (more power needed).
