Empty notification popup

[Uriel Cohen1]

Hey everyone.

I have HTC One m7, and i'm getting empty notification popup from time to time.
This is how it's look like:


Please note that it's not related to what you see in the image background (apn settings)
The message can popup anywhere.

I don't know what to do, can anyone help me ?

Thanks.

Welcome to Android Central! Try wiping the cache partition: https://support.t-mobile.com/docs/DOC-11848

Hey, and thank you for your replay.

I have TWRP recovery (rooted device) , so when I go to recovery, this TWRP come up.
There I have this options on the wipe menu:



What should I choose?
Is this erase my data?

Thanks!

I think "Cache," but I don't have any direct experience with TWRP. Wiping cache should never erase any personal data, though, since it's all temporary.

Ok, i'll try it.
Thanks!

EDIT:
It's not fixed the problem :'(

Ok, try wiping the Dalvik cache. That also shouldn't erase any personal data: android - What is Dalvik and dalvik-cache? - Stack Overflow

I thought it had solved the problem, but unfortunately it did not ..

The thing is, these messages only pop-up in the morning..
Then they jump a few times in a row.
And after that, it's silence until next morning.

I think I gave up.

Apparently there is no choice other than burning a new rom.

Anyway, I'm really appreciate the help!
