Hi, I have android 4.2.2. Not sure if any of the coming details are related, but here goes: - my phone fell today. Looked like all works well. I called, texted etc. - hours later, i was not able to send a text. Got online with the support, and it got fixed. - while dealing with that, i noticed a line that i never saw before, as part of the usual reception icon on top of the mobile screen. It appears only when i enter text/call/contacts screens (as far as i can tell, maybe it will show on other places i didnt check). Anybody knows what this line is? Can i attach a screen picture here? The support guy said it means probably something is wrong with my phone, due to the fall, and i should go and check it. *HERE* is a picture of it. I marked it with a red circle. You can see the thin blue horizontal line just under the reception bars. Who knows what it means? Thanks.
