I have bought a brand new iPad 2. The iPad screen stops responding after (approximately) 2 seconds of inactivity. Immediately after pressing the on/off (sleep/ wake) button I can slide to unlock the iPad and continue to use it if I do not let 2 seconds gap intervene between screen touches. If for any reason I do not touch the screen for 2 seconds the iPad screen stops responding until I push the sleep/wake button again giving me another 2 seconds to go into the same cycle as before. This has been the case ever since I took it out of the box. Have tried restoring and updating the OS but that has not helped. If anyone has faced this and knows the solution - would love to hear from you. Thanks in advance for your help. Additional Info - As long as I keep a finger on it the screen keeps responding.
