Here's one very common test that's been missed out, the 'Fit of rage' test. How many times does it happen that you are so angry that you feel like throwing something against the wall? Well, a lot of times I believe and the only object (mostly) at such times in our hands is our cell phone. I just did it a few days back. I threw my N95 8G against the wall. How angry was I? Just see the impact of my throw on this wall
What happened to the phone? The battery came off and so did the sim card. What hit the wall was the lower right edge of the phone, some color from the wall stuck there otherwise no visible mark/scratch on the phone. I put it back again with shivering hands just hoping that the phone ain't dead. But thank God, the phone's working good. But my keypad lights dont work and ever since that throw I've not been able to get a GPS lock, may be the GPS reciever no longer works.
All thanks to Nokia for making such sturdy phones which can survive almost anything. WOM World people (the place from where I get my phones from) rest assured I would'nt have done it if it were one of your phones ;)
