I'm getting really poor signal performance. It doesn't matter if I'm in town where there's a lot of signal and people with the same sim card company are getting more bars and faster 4 and 5g signal.
Try wiping the cache partition of the phone and that may resolve the issue. Just search 'how to wipe cache partition Galaxy A53' and you should find what you are looking for 😃. Hope this helps! 🙂
