Touch Issues

[Guest sunshinekhan]

i have been using an acer liquid s100 for sometime now and off late i am having issues with touch near the lower end of the screen in apps such as dialer, setting menus, dialog boxes

i would have gone with hardware fault, but the same region of the screen works fine on the home screen and in several other apps

i was on miui 2.3.4 stable on 4.002.14.EMEA.GEN1_A22F_A_256_bin, rooted with Malez ... everything seemed to work fine for a few days and then this issue cropped up

tried LeoGB5.0 and LCR-F_2.0-signed with full wipes in Malez Recovery but the same issues

i then tried flashing 4.008.08.EMEA.VFIT_256_bin as a work around but still no luck

i also tried Clean Boot but the same issue

can someone please guide me so that I can overcome this?
