Then either it is a flaw with CallBar or Springtomize 2 is messing it up, since it is the only other tweak we share.
To replicate the issue, open Safari, go to any random page, rotate your phone so it's landscape, push the sleep/power button so your screen shuts off, and then call your phone. It will be messed up every time.
Very strange, i will mess around with it some more tonight.
