My touchscreen buttons for my Ericsson K850i intermittedly not working. Since Friday, they didnt work. Every time it happens i turn my phone on and off, and most of the time it will work for about 5 minuted with no problems, then it will stop again. They occasionally will then start up again, but it annoying when you suddenly cant unlock your phone, get the menu up, send and texts etc...Please help?
