is anyone having network issues with galaxy z fold 3??

This is what I found on the Samsung forum. So far it seems to have corrected the issue for now. But we will see if it reverts back to in and out service or not.

I followed the directions posted here and I now have service after 4 days of being without service unless I used WiFi and countless useless calls to TMobile and Samsung technical support. Thank you to whoever submitted the work around. I pray that it holds up.

I  havong same issue with no fix.. .tired of speaking to reps and getting no where..

Same problem with me. No one could find an issue after talking to a few different reps in store and online. They ended up doing a warranty exchange. But I'm starting to get the same issue in the replacement as well. It just keeps dropping the network completely.

Same here. After January 28 update connection is worst then horrible. went in the T mobile store and after 30 min they were able to get 2G connection. its a joke. guy gave me phone back and said its good. i told him Im not stupid to be happy with 2G connection on $1800 phone. seems like there is nothing they know/can do so far.  beyond disappointed

One other thing I noticed is to make sure to hit the block set by AP option. Otherwise it will reset the band choices to default if you restart your phone.

After a few hours of removing just the GSM bands and leaving all LTE band, and 5G bands enabled. I began noticing intermittent data drops and poor to unusable call quality.

Messing around it band options this is the most stable and fastest data speeds I've been able to get so far. (Bands selected in photos)

Guys I fixed the problem!

Sincerely, Samsung and T-mobile knew the problem already. I went to the Samsung care store in Texas, dallas. When I told them I have a problem with Galaxy Z fold 3, they knew why I was there!

They explained me what happened. It had been problem with T-mobile android 12 update. This update is something troble with Z fold 3. Only the T-mobile version has the problem so any other carriers are working good. So Samsung just replaced new mainboard as free and it was took only 2 hours for fix. They even provide rental phone (S20+) for free too. After replaced mainboard, they updated android 12 software but it was Samsung version (it was not from T-mobile version). Also, they told me do not update until the software problem is solved. so, I turned off automatic software update. I saw today T-mobile offically notice on there website for this problem. They said just update newest version of they provided softeware. but, I'm not sure that software can be fixed this problem. Hopefully this helpful everyone.

I am too, I haven’t been able to get it fixed yet… let me know if you do!
