I've had a couple of instances of what I assume is the touchscreen bug. Phantom keystrokes etc. What I found interesting was that they only started when I was using the hudl outside (waiting for the bus) in cold weather. As soon as the pad was indoors the problem ceased.
If I find it happening again I'll have to return to stock and return it but it seems that if its a temp issue it suggest that the screens have gone through a poor quality check.
If I conrrect I'm guessing that the temp causes the screen to contract by a marginal amount that then makes the screen register phantom touches.
This is, of course, a half-baked pseudo-technical hypothesis but it seems odd that both times this has happened has been outside during cold weather.
My issues have been indoors - Not phantom keystroke just about 2/3rd of screen from bottom up (Landscape) doesn't respond to input - power off, or let the screen time out and turn it back on and its OK again.
Seems quite intermittent - I had a good play at lunch today Dead Effect, Sky Gamblers - both quite intensive 3d games. All OK
It happened again this morning when I was browsing using Chrome - This was when I had done what I said on previous post (set 2d apps to use GPU) in developer options, so have been using Next browser mostly today. Similar issues reported with Nexus 7's - and there's loads of issues reported with system crashes etc when using Chrome on 4.2.2 based Droid.
Going to see how it goes, but may also revert to stock and return for replacement - I'm in my 14 day period so hoping I can just swap it there and then as I don't think I can live without it now.
Lister, when did it happen on your brothers Hudl? After browsing or was it anytime?
