apparently, that touch screen problem is with most z1's as mentioned in sony and xda forums.

alot of users are frustrated as there are close to 0 response from sony regarding it albeit being posted in sony forums.

i did a test on touch screen  ( setting > about phone > diagnostics > test device > touch screen ). it gives u a 10 sec to conteng the screen. everything went well. do it for the 2nd time and the line keeps breaking after 1-2 secs.
mine was exactly like: http://www.youtube.com/watch?v=oj1P0X12r_A
       

so the z1 sudah masuk category chinese phones?

Do u guys face this problem? When answering incoming call, it auto put to speaker phone?

Wonder what are the major differences btw z1 and z2..
