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

I’ve been seeing these for a couple of weeks now,  I’d rather not do a hard reset if I don’t have to.  Especially if I don’t know if that will stop the pop ups.  If they don’t fix it soon I’ll be bugging customer service again.  I tagged CS on my post but they haven’t chimed in.  Not sure if they haven’t seen it or don’t have an answer. Ugh

Having the same issue with T-Mobile Diagnostics.

I have the same problem.  It just started abt 1 x week ago. My phone just took an update, but it is still doing it… hoped it would have solved the problem… :-(

Add me to the list.  Using an LG V60 and gone through a couple of chat sessions to try to clear up the issue.  They want me to try a hard reset next but even with LG Backup or Google backup some apps (like bank app have to be set up again)  don’t reset.  Has anyone had luck doing hard reset to clear the issue?  Looks like all these responses started in the last couple of days like mine.

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

I have the same issue.  Started about the same time as others report.  I uninstalled & reinstalled app numerous times.  I finally just uninstalled the app & did not reinstall it.

I spoke to customer service and they are working on it.  A lot of people are having the same problem.

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. 

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.

@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. 

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

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 )

I got a follow up call and noted the twenty some odd post here and another thread about the problem.  They're waiting for me to do a hard reset.  I'm gonna try it this evening and see how it goes.  In the meantime they assure they're working on it…

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

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.

@ghostleee

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

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

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. 

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?

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.

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

How did you get the issue solved?

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