@Fish That's great, I'm so glad i could help!

Thank you very much!

@fish activate localisation, open the terminal, type test_gps and wait. Make sure the phone doesn't sleep, is close to an open window, that terminal is set to not interrupt with UT tweak tool, and is on the foreground. You should start seeing a bunch of gps coordinates within 40 minutes. If not, you indeed have an issue.

@fish Firstly I would use UT Tweak Tool to remove telegram. Firstly remove cache, data etc then delete telegram. After that reinstall Telegram from the Openstore and try again.
