[islamahmed]

I want to ask about Sony Xperia Z1

what happens when you press on multitask button 3 time or more repeatedly

because when i press multitask button repeatedly on my Sony Z1 The screen flashes

is that normal or i have problem on my Sony Z1 ?





if anybody can send me a video shows what happens when multitask button pressed repeatedly and what happens when you close all running Apps from multitask i will be very grateful





hope you reply quickly because i only have 5 days until warranty time end

Thanks for your time
