Re: Randomly turns itself on...
 

This hapens to me as well, mostly when flipping in an out of roaming and randomly while driving. I can force the screen to stay off with the application mentioned earlier but this does seem like an unnecessary step. What I would really like is a mod that will keep the screen off when the phone is facing down, like on a desk. The phone has all the hw required (e.g. speakerphone when phone is active and fac down) - is there a setting somewhere i am missing?

Roaming notwithstanding, what most people are seeing is when the phone switches between 1xRTT and EVDO. When the signal to noise ratio drops to a threashold on EVDO, the phone will switch to 1xRTT. This causes the screen to light up. You might notice that in strong EVDO areas, you don't have this problem. I have seen this, as others have wrote, with most/all HTC devices.

I have an Airave and every time I enter my house it will turn on.

I have the same issue too,I also found out that if I stand under a traffic light,my phone screen would turn on when the traffic light chnaged from red to green or whatever,I take train to work everyday,phone screen also turned on just right before the train arrive to the station,this happened 99.9% of the time,if I put my phone in airplane mode,then I never have this problem.My wife has a Samsung flip phone,the above did not happen on her phone even though she just stands next to me.

Now that's just crazy. Cool, but crazy. Must be a radio signal similar to the ones Ambulances, etc use to make a light green as they approach a traffic signal?
