Every time I reboot my phone, the APN setting will just disappear, and I have to type in them again and again and again. When the APN setting is gone, there are signal bars showing, but there is no service available.
This also happens to me. Whenever I restart my phone, the APN settings are just lost. It seems like the default APN settings are left blank, thus the setting will be resetted to nothing from time to time.
Thank you for sharing, but I'm afraid this is not related. For convenience in typing, I often use '1' or 'Q' as a name. I don't think any prebuilt setting profile would have the same name.
It's a S24 plus as I have said. I bought it in Canada. So I believe it's a mainstream phone, shouldn't be anything wrong with that. There are too much information in my phone to reset it sadly.
