Unstable / inconsistant mobile network data

Jynn

Hello,

It's been few months that I have inconsistant mobile network, it works sometimes but expire other and completely randomly. I tried various methods to try to fix the problem :

Reset APN & network settings (also rebooting the phone after doing so)
Allowed 2G
Changed my provider
Tried it on another phone and it worked
Also my friends who have the same provider do get network but my phone shows no signal

This is annoying because it can last for several minutes and call that I receive in that time are completely voided.

I need your help please!

Jynn

Any ideas?

It could be a hardware problem if none of those things are fixing it and especially since you changed carrier with new sim etc. Maybe you dropped the phone at some point before it started happening.

It's possible because I changed carrier already because this was happening.
I always had a case for the phone and it has no apparent damage tho.

After many tests, the problem comes from my antenna.

My only question now is: if I reverse to stock OS again and send it to Google for repair, will they even check and can they refuse because I was on GrapheneOS?

I don't believe there have been any reports of this happening.

de0u I checked on some forum apparently they have a device that scan the phone and if the bootloader has been unlocked they know about it and refuse to fix using warranty, might charge fees for it

"Some forum" is not sufficient detail to be actionable. On "some forum" there are lots of posts about the Earth being flat instead of a sphere, Queen Elizabeth of England having been a lizard (source), and so on.

Providing a link to a report about a Pixel user being refused warranty service for running GrapheneOS would be of interest.
