Have set screen lock to 1 minute, but when I have

ok this model of phone has a sensitive screen and will cause the screen to have a slight malfunction if it is repeatedly touched. you really want that screen locked as soon as it can. you can set the screen to wait a little long but i also have this model of phone and if your talking on it with the screen unlocked you will scramble the calibration on the screen. to repair the calibration you go to the four little dots hit it go to the settings wheel at the bottom right. ok now go to more . go to touch calibrations at go thru the calibration of the touch screen it may tell you that your off a few times but dont worry this is normal. continue thru the steps and save when you feel you have it set to your liking.
