Hello. I have a very simple problem with my ipad that drives me INSANE. My screen feels sticky. it's not sticky that much but I can not softly slide my finger on the screen, and it really prevents playing games, writing with hand, painting and simple (but important) stuff like that. I did not clean my ipa with anything other thana drop of water and mirofiber so far. I did not use any chemicals on it. Did not stick or remove anything of it. I'm using it exactly as I should, but after 3 weeks of using it, I felt this feeling in the starting of this week. Right now it's driving me insane, literally !! I searched / googled about this simple problem, but most of the people having the same problem somehow used chemicals on their screens. I bought my ipad from another country so it seems like its impossible for me to take it to the warranty check within a sooner time range. Any ideas ?!
