I'm back, new Defy, same problem!
Hello again, 19th November 2011 my carreer gived me a new Defy becouse of this touch screen problem as I've posted before (in September they already gived me a new one becouse of the already known speeker problem) 1th March they gived me another one becouse of this problem... again...
When I where in my carreer store, the girl wich I've talked to tested it, and it wont fail, rare... I told her, let me see, 10 seconds using it and FAIL again.
They flashed it twice, and it failed again and again.
So this is my 4th Motorola Defy, a total FAIL.
My girlfriend has a Motorola Defy too, and... There's something rare... When I do the same things that I've done with my previous failing Defy's IT FAILS TOO!
BUT
When she uses it, it wont fail (rare?)
So the problem is that it has a crappy screen and of course, me. I don't know why, couse with the new Defys it doesn't happen, is like the screen waste it self with the time using it, I've tested the same things that I do to make the Defy fail on a Galaxy S, HTC Nexus One and HTC Sensation 4G (they where older than 5 monts, the Defy that lasted more for me where 3 monts...) and they wont fail.
Motorola, (IMO) you failed with this "life proof" phone, first, speeker fail, and... double touch screen fail.
As they gived me the new one, (never plugged on it, it has film all over the case/buttons/screen, battery stills in it's bag etc) I've put it in it's original box, and I'm selling it on MercadoLibre (it's like our local eBay page).
CYA Motorola Defy, not so nice to meet you, and thanks for generating a lot of stress on me xD
Sorry I can't help, there's no flashing fix, this is a hardware fail (read my previus posts).
Now, I'm really out. Cheerz.
