This is driving me nuts it's been going on for a year! I have tried all the different tricks and called Tmobile and was told again to do said tricks and the most overused word of the 2020's besides cringe would be insert word ______  hack.🤬🤬 Stop it! Just stop it! I don't want a cookie cutter "hack" when it's not a 3rd party Apps like Door Dash, YouTube, Twitter, and Facebook. It's you the provider's App so just give me a straightforward solution for what is supposed to be by all these people dealing with same problem a straightforward service problem.  There's absolutely no excuse for a year to pass and I am still having this problem and it happening on my upgraded new phone while it happened on my old phone for it to transfer to my completely different new phone also considering the back doesn't even come off the phone (horrible design flaw seriously what are we doing Tmobile? Get your shit together. ) and it's prepaid so there shouldn't be a traditional sim card, so I am still not seeing the problem or better way of saying it I don't understand why this problem even exists. Finally back to my point (sorry about this ridiculous diatribe.) But the technical support shouldn't be trying to teach "hacks or ways to cut corners.) Again you provider me customer straight forward Transaction and should be a straight forward solution for what seems like a straight forward problem. (Sorry about the overuse of straight forward, but just trying to get a point across that I shouldn't even be having to make.) So yeah Tmobile I've already got your next 5-year New Years resolution lined out, right? Just be a better freaking company. The company that me, my friends, and all of my family members enthusiastically joined, because your reputation was so stellar! So yeah anyways, yeah ya'll can keep my soap box hope I won't need it again it regards to this specific issue and Tmobile doesn't fix this then we keep doing what we have been doing and cause a ground swell and changes will happen. Ok everybody I am exhausted literaturely.(see just making up words. This is what burntout looks like kids )

We have 2 lines on our account my phone is good,, the 2nd line just started getting this message today on a Galaxy S20 FE 5G.

Has there been any resolution?

Hank313 Make sure your phone has the latest updates and if that doesn’t stop it then contact TMobile online or by phone.  Stay in touch until it clears up.  That’s what I did.  Someone else in this group did a hard reset and it didn’t stop the popup.  

I keep getting the popup mesage. "T-Mobile keeps stopping". It pops up every 15 to 20 seconds. I have tried several things but I am not doing a hard reset. I took it to a T-Mobile store and they could not figure it out. They told me to uninstall the app and reinstall it. I tried but it won't alow me to uninstall the app.

@charjeanne thank you I went in a forced a stop on the app settings after I cleaned the catch and so far...(knock on wood) it has worked. 

Hi Krine143, It was really bad back when I first posted this but mine has since cleared and it isn’t happening anymore.Stay in touch with T-Mobile and let them know you are still getting it.  I hope it clears up for you soon.

I have contacted then. Cleared data and catch restarted phone lots of times. I keep getting the pop ups T-Mobile has stopped working. Anyone get it fixed? Any ideas at first it was not annoying but now it's been a little over a month and it is now. Also my app cleaner pops up I click it to try and clean apps and it just shows the pop up again T-Mobile not working and then clears out the app cleaner but then now the app cleaner pops up at least 3-4 times a day and repeats the cycle. Then I get the pop up of TMobile not working in-between that. 

I didn’t do anything, they just stopped.  If you still have the problem let T-Mobile know.

How did you get the issue solved?

So glad the problem was solved.  If you are still getting the pop-up contact T-Mobile.  My pop-ups have stopped.

T-mobile app keeps stopping, so irritating. Why can’t they fix this???

Yeah, the one about them being hacked takes priority i’m sure.  The popup doesn’t seem to be happening as often, that’s a good sign. 

I'll have to wait for a response.  Looks like they're dealing with a lot issues:

Yes I’m still getting it.  Haven’t seen the feedback option. That’s new.  

CS also gave me a discount.  Hope they get it fixed soon.

UPDATE:. The brand new warranty replacement has began doing the same thing with the T-Mobile & T-Mobile Diagnostics app.  Those plus a few others that "keep stopping". Tried online to get assistance only to get this.  I guess the issue an ongoing problem.  Anyone else still having this problem?

@ghostleee

Thanks, but latest update already done, cleared both app cache, and data, numerous times, pop-up still occurs.

Thanks Ghostlee13.  I have been in touch with CS again this morning and was told they are still working on the problem.  I do have the update and as of yesterday I was still getting the popup.  I will wait, they will fix it eventually. 

Check the Google Play Store for an update to the T-Mobile app. That should resolve the issue, but I'd clear the app cache and data as well, just to make sure.

No, it hasn’t stopped.  I’m still getting “T-Mobile keeps stopping”  however it seems its not happening as often.

Let us know if you see it on the new phone.

Ok late follow up on the issue(s).  Appears there are two separate apps with issues; T-Mobile & T-Mobile Diagnostics.  The latter kept crashing on my phone that lead to a hard reset that didn't work with the phone being exchanged under warranty.  Upon getting the new replacement the T-Mobile app (where this community is launched from) kept crashing making 8t difficult to communicate with TM.  At least for now the pop up notifications from the Diagnostics app have stopped.  

Bottom line:. Is the issue fixed?  Are y'all still having problems?  I'm hoping the replacement phone won't have the same problems.  

I’m late to the party and posted this in another thread, no luck so far, so I’ll wait to see what happens here.  I have Samsung Galaxy S8, still working fine except now for about a month or more I keep getting a “T-Mobile keeps stopping,” screen that pops up randomly.  Not sure what that is?  But it’s really annoying.

Finished with CS, there was one popup after the hard reset.  I would hold off on doing that unless/until T-Mobile says that IS the fix to this problem.  They said they're still working on the issue.  I'll follow up later on and see how this goes.  Hope this helps.

Don't do hard reset now.  Hard reset didn't clear.  On-line with CS.  Will update later

Restore still in progress.  After it completes I'll post if the pop ups stop after it's complete.  

Thats a little different than mine, mine just says “T-Mobile keeps stopping”  I look forward to hearing if your reset works.
