Problems after system update

i got the exact same issue with A53, not receiving calls since system update sometime in September.

useless phone. it is more of a music player/storage device, nothing more.

This is an issue that happened on all Samsung A536E variant after the July Security Patch (Latest on this model variant)

Samsung has been pretty much ignoring this (Big) issue (whether on purpose or not)  the only fix is to roll back your Android OS Firmware to the previous patch using ODIN.

This is the functional Firmware. > A536EXXU2AVF2

This is the latest July on the A536E variant that broke calling A536EXXU2AVG1 < do not install

Also happened on A235M Variant (A23)
 

So, looks like the recent update, either the July or Aug 2022 from Samsung, somehow messed up the connection to 4g or 5g. I found that by changing the “Network Mode” to 3G/2G has resolved my SMS and MMS problems. Not an ideal solution so hopefully the next update or hotfix will correct this bug.

I am on a Samsung A52 5G.

Settings → Connections → Mobile Networks → Network mode → change to “3G/2G”

mind posting which update it is? i’ll ask but im going to need that update info as well.

and are calls the only issue or texting as well? regular texts=sms and pic texts/group texts are MMS...issues with either of those as well or just calls?

havent heard anything on that one..only got feedback on the 52.

Did they give you a fix on the A52?  My A52 started sending all of my calls to voicemail after an update a few days ago.  As a call is coming in, the cell strength bars at the top of my screen turn to the Do Not Disturb symbol.  I even tried a factory reset. :(

Thank you. I actually did buy a Motorola...

European devices even though they are named the same thing dont always have the same bands needed over here in the U.S.

if thats the case you’ll want to be looking into a new phone here in the near future.

a lot of problems after last app update

No I bought it in France and I don't think it does that's what they're telling me it doesn't have LTE...

side question though. was your A32 purchased from TMO? and does it have VoLTE (Voice over LTE) capabilities by chance.

if it does not it will not be working very well once they dump their 3G side of things..the 3G side is usually used for voice and regular texts..but soon both of those will be going over 4G but only if you have VoLTE.

if it doesnt it might be getting to be about that time to upgrade
