cell phone keeps vibrating will not turn on | Tom's Guide ...
Jan 31, 2011· SOLUTION !!! Hey i share your pain... i have an S2 as well and have been facing the same problem... my phone is rooted so at first i thought the problem was due to an unstable custom rom... anyway the REAL problem is called a "STICKY POWER KEY". all you need is a bright light, a can of CRC (the none conductive type) and a Phillips head screw driver.. you need to remove the back .
