Glad they could fix it so quickly.Had exactly same issue here. After accidently destroying my Lumia 925's screen allready for the third time (Allthough phone still works after a swim in lake in my pocket, drop on concrete and beeing forgotten on bonnet with all the consequences. I would suggest it is in quite perfect condition - only the screen should be replaced and blown vibra and button's backlight fuses changed) I went for a new Lumia 830. The first glitch I noticed was an oversensitive search button. If screen was set to very-sensitive mode (in order to use it with gloves) the search button would hit by itself. It's kind of disturbing when you read some news, write an e-mail or just play some game. So I switched back to normal sensitivity and the bug was gone. By then I was planning to return the phone to my carrier after six months mandatory period and repair my Lumia 925 once again. After a month or so I was wiping the screen and noticed that funny glue-sticking-noise. Looked carefully and found out that I was able to stick my VISA easily under it. So the next morning I took my 830 to my carrier's office and they accepted it on behalf EU warranty regulations or whatsoever. The guy in shop said it's not the first time him seeing a loose screen on 830. So after 6 days my phone is back - the screen has been replaced, everything looks firm now and I didn't have to pay a single Eurocent for that. Let's see if that fix holds and I am thinking about rather keeping my 830 than reanimating the 925 for now.
Please let me know...The same thing exactly happened to my Lumia 830 two weeks ago; it's on repair now.
I'll report back later.
So you have got your phone back, or is it still in Service Centre?The same thing exactly happened to my Lumia 830 two weeks ago; it's on repair now.
I'll report back later.
So due to bright spots you had to replace display unit?The phone returned today.
The whole display unit got exchanged. Aside from the loosening display unit, the display showed four bright spots only to be seen on a bright background; another problem widely discussed.
