How to solve iPhone 5s screen orientation problem?

Question

iPhone

I took the device from my hands, everything was buzzing, but there was a problem with changing the screen orientation.
Apparatus 32GB model A1533
Tried and hard reset and restored from ayukloud, erased, then with aytyunmyasya and so on ...
The orientation lock icon turned on and off.
Compass when calibrating the ball on the right - 0 emotions
But what is most interesting ...
The fact that even through Assistive touch when you try to turn the screen also 0 emotions ..
it turns out, most likely, a software problem ... Not a device ...
Someone faced it? How was/was treated?

Answer 1

It turns out that the phone is faulty.
The accelerometer can hardly be soldered.
It is best to return the device to the seller.

Answer 2

Yes, software is sooo unlikely that something broke. The problem is most likely hardware.

Answer 3

Mechanical damage is not treated programmatically. It can be seen that the accelerometer has already been repaired and while the phone was working for you, they sold it.
