A couple weird things since the update, any help would be appreciated. 1) I answer the phone and the screen immediately dims/goes to black before I even get it to my ear or have the time to hit speaker, dialpad for touchtone selections, etc. 2)I hang up, it goes to call log, screen immediately dims then fades to black, and phone goes to sleep. I have to hit power button, unlock the phone, and it takes me back to call log where I have to then exit the phone app. I am totally annoyed and would appreciate any advice! Thanks a bunch!
