Hello can someone tell me why it could be that my Huawei phone, after I have started it up and unlocked the sim and the spear screen automatically shuts down?
Can only imagine that it is a soft or hardware problem! Would recommend you to the dealer, where you're going, because of warranty!
Maybe it can also be a loose contact on the battery?
No.
For security reasons, devices often automatically turn off (or reduce their power) when they overheat. This is usually due to the battery - at least for smartphones. Possibly. Do you exchange that once.
(For computers, for example, there may be a reason that they are not adequately cooled, but that's only marginally)
