I got my lumia 720 three months back.
It was working fine.
Suddenly day before yesterday my 3 touch keys(back,search,windows) didnt work.
So i reset my phone.
And after that i found that, From bottom to about 2.5 cm touch is not at all working throughout that area.
Please help me.
After reset two options ll be there. Emergency call and get started. M not able to select any. Because it is within that area where touch is not working
