My s23 lost its 5g connection on a weekend road trip and that was a big problem. Tried all the normal things: hard reset the phone, reinsert the sim card etc but nothing helped. After rebooting, the Rogers & 5g icons would briefly appear and quickly vanish. After I got home I reset the settings and, though losing all the various network passwords and bluetooth connections was annoying, 5g is working again. HOWEVER, it now seems that if wifi is enabled the 5g connection is automatically disabled. In the past I had always left wifi enabled so that my data would use that instead of 5g if a wifi connection was found. Has something changed? The phone is current with all updates, One UI 7 (July 10) on Android 15.
