I have never experienced such an issue. And, to comment on your "next device", don't do it!!!!!! You will miss android greatly.
I won't i have my optimus s, its not worth the upgrade this year, half of these devices are on gingerbread, and Ice Cream Sandwich is just around the corner, upgrading those gingergread devices to Ice Cream will take be a drag, and with the IPhone, updates are given on one day across all devices, and all apps work across most devices, its simpler, the screen is amazing, not even SAMOLED+ can match it, ill jump back on Android after Ice Cream Sandwich....
My going mumbo jumbo I mean when I touch the screen, itll touch it somewhere else, itll be doing some weird stuff, i touch the top, it touches the left corner, I touch the bottom, it touches the top, its random, happens rarely, like 1 or 2 a month, but very annoying..
