Hello everyone. So i have the following problem. Right after i unlock my phone i have location service icon in my status bar. Probably it is also on when device is locked and in "deepsleep". I have this problem on different roms, different kernels after clean installs. I assume google play services use it and dont know how to disable it without harming anything important. Any suggestions how to fix this ?

if you can place phone calls with it, it means that is not locked, so the next thing you should follow are the APN settings.
Follow this guide on how to check your APN settings; https://www.unlockunit.com/blog/apn-settings-not-available-current-user-profile
And if they are not the correct one, you can contact your network provider to provide them for you. Let me know if you fix them.
