Black popup displaying 'e7' and 'ok', Why?

[Uditsh]

Hello All,
Can anyone please tell me about 'e7'? I am getting a black popup displaying only 'e7' and then 'ok' in my phone frequently.

Just saw your thread and made a little search. There's not much information about that message. Besides your posts in different forums I just found a reference to a call tracker. Take a look here.

My suggestion could be booting your phone into safe mode and see if the same message pops up. That's a way to know if an app is acting weird.
