Hey everyone,

Two days ago I got the new update, I believe it is OxygenOS 12.1?

While it claims improved stability, the opposite is true for me, especially regarding mobile network connections.

About the new version, the update-log specifically says "Communication: Improves the stability of mobile network connections."

However, after the update, I can now only stay on my mobile network for 5-10 minutes before it shows the exclamation-mark error in the top right corner on the connection status, and the network doesn't work.
I then have to go into the settings, disable my SIM-card, enable it again, and then it works for 5-10 minutes again before it stops working again.

Before the new update, I used to have zero issues with my mobile network connection.

WiFi works fine, the issue is only regarding mobile network connection.

Does anyone know what I can do to fix this?

Please let me know if you need any further information about my phone.

Thanks in advance

Depending on your model you may not have a local update option. If not, then install this apk

Be aware that this will erase all of your data and unroot your phone
