My HTC Evo 4G has the black or blank screen problem when starting

[daxlw]

When I start the app the camera symbol starts up but then goes to a blank or black screen. The only way out is to hit the home button. Who knows the fix. My phone is updated and has the pre-loaded apps only. Hard restarts and flashing does not seem to work. This problem is all over the internet. Help.

Is your phone rooted?

Try clearing the cache in the camera

I cleared the cache. Nothing. My phone is not rooted.

I don't know how this worked but I took the battery out and pressed hard on the camera lens. It had a small snap. Restart. It works now.
