- Huawei P9 - the sound works, after a while there is no sound of connections an

Hello.
After the software update (on EMUI 5.0, build number EVA-L09C432B378) a rather strange problem appeared. The phone worked beautifully until finally there is no ringing tone and other notifications, sound of all applications, I can not watch video on portals like instagram, facebook or snapchat. The alarm clock and the bell work on the vibrations themselves. In the sound settings, all are set to full and nothing improves. After restarting the phone is okay, but again to time. I do not know how to do it. Maybe someone would be able to advise something? I restored the factory data, but it did not help. I am waiting patiently for help.

Huawei
Not my story

But this is how it looks like my phones as I do updates from the phone, not under the laptop cable.
Once there will be a raspberry and once an inactive alarm clock or contacts that can not be removed

I would recommend once again to update the software from the computer.

Start with a reset. If it is impossible to upload new software as a colleague wrote above.
