This is really wierd
I bought my first HTC One X last week and i realized it had some problems so i exchanged it to another one last friday. They let me try the new phone in the store so i could see if there was any glitches, i tried the web browser, youtube and looked for the gray flickering areas, i didn't find anything. I really appreciate Netonets good service here in Malmö,Sweden.
On saturday morning i noticed the glitches on my phone so i started to make some video clips of me watching a clip on youtube, and changing tabs in the web browser and also reading on gReader Pro.
I sent an e-mail to HTC (haven't heard anything from HTc), XDA-Developers, pocketnow and AndroidCentral with the link to the post and videoclips:

Now, i can't reproduce any of these errors/glitches/flickering as much as i try. I don't want to reset my phone to try to make the problem appear again.
My battery level is on full and i will leave it over night and not recharge it to see if the problems show up when the battery is low or not close to full. For a few days i've been running the nova launcher and turned off the Animation and USB Debugging in the developer options. So i noticed that there was no glitches anymore so i was thinking it was because of that. So i went back to the Sense launcher and turned on the animations. Still i can't see any glitches.
My serial number on the phone is starting with: HT23 and yes this is the "faulty" phone that i posted about earlier with the youtube clips.
As late as yesterday, i was thinking as many of you do - should i return it or wait. Now im really confused, it's difficult to be happy about a problem that has disappeared.
