Question about Sony Ericsson K850i Mobile Phone

1 Answer

Pressing no: 4 leads to switch off the screen of SE k850

If I press number 4 button of my SE K850 makes turn-off the screen of the phone. But after sometime(after keypad light also goes off) by pressing a key, screen will comes up usually. Only screen or backlight of the screen is turned-off . Not even no:4 if I press empty area which just right to the no: 4 key makes screen off. My friend also has this problem, who bought the phone from a shop which is just next to the shop which is I bought.

If Some has a solution to this please kind enough to inform, because It is very hard to text from my phone now!!
