I've had Sprint since 1997, part of that time in the midwest and part on the west coast. I've literally had more network problems in the last two months than I did in the previous 23 years combined. A couple of months ago I noticed a VoLTE icon show up in the menu bar on my Galaxy S8. This coincided with network changes due to the TMobile merger. Ever since then it's been constant dropped calls, roaming all over, complete loss of signal, restart after restart, etc, etc.
From my home office, where I've worked for years with few problems, I can no longer get a reliable signal. I tried the tech support route a month ago and got the basic troubleshooting responses. The phone worked enough to satisfy tech support but since then it's been having the same intermittent problems. I tried again today and opened a new case, reluctantly because I know every call is at least a 45 minute endeavor. But my phone had shown no signal for hours so I had to bite the bullet.
After the usual steps, signal bars showed back up. When I attempted a call later though it would not go through. I then tested inbound calls and those failed as well. So another call back to tech support and some more troubleshooting got it working again. This time we did a ##72786# reset on the phone.
So it's working now but who knows for how long. Signal strength is not impressive:
I'm wondering if there is anything else I could possibly do on my end to improve this situation - different phone settings, etc? And of course, the phone has all updates installed.
there was a security patch that ended up creating some issues for a decent range of Samsung devices...yours included in said security patches..main reason i have been asking what i have been asking about the device..mobile data signal drop along with a few other added issues.. which was kicked out roughly about the time you said you started having issues... it affected the S8 and up to the A11
