My proximity sensor went wonky upon updating. Tried clearing caches, etc. Going to try starting fresh.
Once I had a Nokia 6015i, but it wasn't smart enough.
Then I had a Helio Ocean, but Helio went adrift.
Then I had a Palm Pre, but that ended PREmaturely.
Then I had an HTC Evo 4G, and we had a grand times!
Now I have an HTC Evo 4G LTE, and all is right with the world.
