Connexion problem since Android update of August 5th 2025

[Lucius_Marcus]

Hello, I have a Samsung Galaxy A53. It seems to be since the Android update of August 5th. I have now a very bad connexion to the mobile network. When I am on the phone, everybody says that they have a hard time hearing me. Also, only one or two, or even none of the four bars indicating the strength of the signal is filled in.

I tried to solve this by restarting the phone, by resetting the network setting and by choosing the 4 G instead of the 5 G. Nothing seems to work.

What should I do?

I rebooted multiple times. And I just tried to reset the network settings a second time. I confirm that my phone is VoLTE capable. Also, I

tried the three options : 3G, 4G and 5G, with no success. As indicated by the four bars, the strengh of the signal is weak (at the moment, no bar is lit up). I will try other solutions tomorrow. Thanks for your help!

First Reboot and Reset Network Settings and try again

Also, try to change the network mode to 3G and see if voice calls are better 

And confirm if your phone is VoLTE whitelisted using the IMEI checker here

here's some light reading regarding VoLTE. At the bottom of the page is a cellphone checker you can use to see if yours is VoLTE ready.
