Hello,
I've been facing issues with my Samsung galaxy A54 lately. My cell signal keeps disconnecting itself, and my sim cards stop recognizing the network. When I try to call somebody, it shows a prompt saying "Not registered in the network". I've tried changing the sim slots, the sim cards, but to no avail (the same sim cards work on other phones, so the area coverage/operator issues are ruled out). Sometimes I get the signal, when I turn airplane mode on and then off, but the connection lasts 2-3 minutes at max. Sometimes the connection reestablishes and it functions for half an hour, then the phone turns into a brick again. No similar issues arise with wifi or bluetooth. This issue started happening after upgrading my phone to android 17 and the last version of OneUI. I also was faced once during the same period with a "phone overheating, disconnected from charger" prompt when I was charging my phone while it was in my pocket. Can't rule out if it's hardware or software issues at this point. Tried running the *#0011# command on my phone several times, ChatGPT ruled that it was a signal issue, as my phone couldn't connect to the cell towers.
What's the diagnostic procedure to adhere to from this point on? I guess repairing the antennae wouldn't be worth it as this point, as from a financial perspective it would be better to buy a new phone. Thanks for any help!
