Signal Messenger responsible for GSM bad data connection

[ryba35]

Just to help those who still have some GSM bad data/calls problems.

Short Summary: I was able to recover a good GSM signal quality just by removing Signal Messenger application.

It has been a while now that I try to understand why the 4G connection is so bad with my FP2. I run FairPhone Open and use Signal Messenger as main chat application.
After reading a lot of posts about the same problem (resolving-bad-signal-call-partners-don-t-hear-me, no-signal-bad-data-connection), I tried this suggestion:

@DocEmily

You said you did everything Fairphone recommended. Did you also reboot your Device in safe mode?
(Push Power Button as if you want to shut down your Phone but then longpress on “Shut Down” on the screen. Then it restarts in safe mode. Note that you have to put your widgets back on the screens if you restart in normal mode. But safe mode doesn’t affect your data.)
In Safe Mode all your downloaded apps are inactiv. If the Problem doesn’t occur in safe mode one of your installed apps may cause the problem. Therefore you can only uninstall one by one and check. (Be sure to backup data or sync with google).

And indeed, in my case, GSM was working great just by rebooting in safe mode. Then, it didn’t take a lot of time to find the guilty app: after removing Signal, all GSM problems were solved…

Hope this helps,

Could you provide instructions on how to remove the Signal Messenger please? (I’m very limited in my tech abilities! )

Sorry for the late answer. Signal Messenger is not part of the FairPhone Open OS by default. So you should remove it… the same way you installed it
I mean, I installed Signal using Yalp Store and removed it the same way.
By the way, I switched to Conversations as a replacement messaging tool and it works great.
