I have been using it for a couple days now and I can tell you I thought it was me not properly touching the screen or not hitting the right spot. Or I think I'm doing
So I kept going and it mostly works. I then figured let me disable the hep. feed back see if that helps.
But even with all that it definitely completely stops working and seriously won't work, that is at least it seems to me until the opposite button is pressed, it won't respond it is very frustrating. I sometimes have to do like a little tap dance between the two buttons to get something to happen.
Even with that it is to me the most disappointing part so far with. Which will hopefully probably can be fixed in an update. The phone is still great and it happens a couple times a day but I still like the phone. I have some video and ilk try to put it up.
