Question T T-Mobile Z Fold 3 loses connection after update to Android 12

How absolutely F**KING ANNOYING!!!

Here, in my area, I was told to reset the network every time I had an issue, the problem with that, is that I have to reestablish ALL of my network connections again (WiFi and BT mainly which is a PITA)... so... I used Airplane Mode on and then waited and then off and let it reconnect and this works about 60% of the time.

I want to try this to see if it helps, but holy hell why when you lose it after a reboot? I auto-reboot once a week and manually sometimes when I really can't get Data without restarting.

Painful.

Yes, you have to redo it after a reboot, but it doesn't take long to do, and I haven't tried it, but you might be able to just do the "apply" option since the asterisks are still there after the reboot. This should fix the problem you get for data, so you shouldn't have to reboot for that reason anymore.

ETA: I researched what the Block AP option was and that apparently will prevent you from having to redo this after reboot!

I did this based on a post on Samsung Members previously (you can see that screenshot in my post in the cell reception thread here), but I haven't seen the instructions with the Block AP option in it. What does that do, do you know?

I've seen instructions with both the SA and NSA versions of the 5G selections to choose, too.

ETA: Based on my research, the Block by AP option prevents you from having to redo this after rebooting the phone.

Thanks guys! I just did this and I guess we'll see over the next few days how this works.

Yeah, one day out and I am STILL having connection issues, even after applying these settings. I am going to head to a T-Mobile store later and throw this thing (well, something else) at them and tell them to figure it out.

Nah, the guys at the store are awesome, I'll see what they have to say.

Strange. What are your connection issues? Maybe it is something different than everyone else is having. I hope the store can help you, as I've never been to a T-mobile store and only have been in a Sprint store like three times (before online phone ordering) in the 21 years I've been using their service, so I don't know how much the store people know.

The problem is the mainboard itself, I got replacement from Samsung, which has perfect connection on Android 11, I updated to 12 without any issue. I tried to downgrade the old one back to 11 and the connection issue is still there.

This does not happen all the time, but it happens often enough to where I am worried about work (I am On-Call most of the time and need to be able to get calls).

I am on WiFi when home. Pretty normal.
I leave home and I MIGHT have data/voice
If I do not, I normally put my phone in Airplane Mode and then back out again and things are okay
If I am driving and move to a new tower, there is a 50/50 change I will need to airplane mode again to get voice/data

Resetting network connections (which is what T-Mo told me to do every time) works, but then you have to log back into WiFi and reconnect all your BT devices again, so this is definitely a NO-GO for me.

edit: Here are my settings using the instructions in the OP:

Just curious, but why do folks think this is a hardware issue ? Everyone's hardware failed after update ? I have the issue but following the procedure in the service menu seemed to take care of it for now at least .

Hmm, that is a strange issue! I haven't had problems when driving around locally or two hours away (prior to this temporary fix, but I've had the issue for a while, not just since 12 came out; I haven't driven far since applying the fix, but don't think I have had an issue with it - I did have an issue with WiFi tethering not connecting to my car stereo one day, but I don't know if that was after the fix or not).

ETA: I checked my Google Maps Timelime and that tethering issue happened before the fix.

We lost internet here at work the other day, turned on tethering on the device, laptop would connect but no internet.

Do you have tethering as part of your cell plan? If not, it might not allow you to use it even if you are willing to pay for it. Tethering works well on this phone for me, although T-mobile removed Bluetooth tethering as an option for some reason, so only WiFi tethering is an option. My plan comes with 60 GB of tethering, so no issues for me.

It's part of our family plan.

So, just an update here.

When I originally made the changes, somehow it reverted and the issue still persisted.

I have the changes applied now and have done a few reboots and the settings have stuck.

I have NOT had the issues I explained above since these settings have "stuck", so take that as you like, but as of now, I have not had connectivity issues and all seems to be working well.

I did those settings yesterday afternoon and made it worse..........wouldn't pick up 5g. Finally did a chat session with T-mobile and finally got 5g again.
I did notice earlier in the week that the device kept dropping calls left and right, not sure what was causing that.

Did T-mobile say anything about fixing these issues?

 

[ycats]

No.

So 3 weeks in after the update and still experiencing horrible data network issues. I drive a lot and this thing has become pretty much unusable on the road. Tmobile offered me to either receive a refurbished Fold 3 as a replacement or to switch to different phone altogether. As much as I love the Fold 3, I might not have any other choice. Have you guys replaced your Fold 3?

I don't have the money to switch to a different phone even if I wanted to, but I love this phone. I just hope they fix it so it can roam. I have the temporary fix on it and that makes it work, but roaming will be helpful for longer driving distances, especially since I tether my Android car stereo to my phone for Google Maps while driving and other apps while sitting in a parking lot etc.

Does the temporary fix not work for you?
