Samsung A52S is a sub standard phone. Very basic thing for any phone is to recover from no signal condition when it comes to good signal area. How ever, this phone doesn't recover signal automatically and it requires reboot [at times, multiple times]...

Even i m also facinf the same issue. Its very disturbing and annoying noise all of a sudden in b/n a call. Its very frequent almost happens for each and every call. Request Samsung to address with high priority please.
