"tmobile diagnostics keeps stopping" galaxy s20 pop-up

Same issues on my fold 3

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.

S21+ owner here. Like others, disabling the Diagnostics Metrics seemed to work for a while, but it came back with a vengeance. After coming back to this forum and seeing no solutions, I tried this:

1. Disabled all app’s permissions except "Phone" (it wouldn't let me disable "Phone").
2. Cleared the app's data (under Storage).

Since then, no more pop-ups (yet?). Good luck!
 

I am running the Nord N10. Diagnostic has been crashing for days with a popup. I waited to see if they would fix the issue, but ended up disabling all TMobile apps on my phone, and removed all updates. I will not reset and loose all my settings

Happening on my note 20 ultra. My phone is useless tried contacting service and they told me nothing is wrong. Well when I am giving presentations at work and the app force closes and pauses videos something is wrong. I guess it is time to move my business and my phone to another network that works. Cause TMobile has no answer. What a joke. Yes I have reset cache and data on 12 different phones. Still have the same problem. 

Thanks! Hopefully this works.

Clearing the app permissions worked for me as someone stated above. Using an s21 Ultra also had the issue after an update.

Samsung Galaxy A52 5G; same issue.

I feel like turning its notification off is a temporary fix. Hopefully it will be resolved soon and not become a security issue.

Didn't this happen after the big leak?

I ended up opting out of Metrics Collection using the Tmobile app by declining both options as shown in the image. That seemed to have fixed the problem as it has since been 7 days and I've not gotten the error message again.

I've been having this problem for the last several days on my OnePlus 9 as well. Tried disabling diagnostics and it's still popping up. Hopefully T-Mobile can get this fixed soon. It's inconvenient when it's happening really frequently.

What’s the name of the app? Not finding the icon you described. Thank you.

The memory usage is incredibly high for a "background app" post-update. Something happened with the programming here. Clearing the storage for the app didn't work, and rolling back updates didn't either.

Does T-mobile not monitor these chats?

WHY is no one from our service provider chiming in to help us?

BTW- If you have an S10 like I did, DO NOT "upgrade" to this garbage S21

The wonder of tomorrow 5G has done NO THING for me, and the phone asthetics looks like my eldeely mother's Samsung A something that I paid about $100 for, $900 cheaper than this thing. I miss my elegant S-10.  That phone did everything I wanted and looked like a gem, but didn't have the SUPERFAST 5G!  (What a gimmick) 

Let my dark tale be a warning. I may get deleted. Please feel empathy for me (And this garbage phone)

P.S. My beautiful fast S10, it Never had this stupid pop up we can't stop that t-mobile isn't helping us with in here. 

I'm unhappy,  and I have an ugly SHIT phone.  (Maybe the curse word will gain for us a MODERATOR FROM T-MOBILE). 

please remember me guys... I took one for the team!  "Go on without meeeee!!!"

and my Shit21. (See what I did there)
