I'm having other issues with mine since the update:
1) completely randomly; receiving text messages stops giving vibrate and sound notifications. status bar still shows notification, but no notification sound and no vibrate. a reboot solves it for a little while; sometimes a couple hours, sometimes a couple days. even if I set it to vibrate only, it still doesn't vibrate.
2) like clockwork, about 6 hours after last reboot, playing voicemails only plays them via speakerphone (default is set to earpiece). trying to change where it plays from gives a warning saying Bluetooth is connected and cannot be played via speakerphone (even though it is playing from speakerphone, and Bluetooth is disabled). reboot solves it for about 6 hours again.
3) touchscreen loses its calibration, mainly regarding swipes. this is completely random and sometimes works fine, sometime its a pita and will barely let me swipe anything left/right and/or up/down
4) text messages no longer display in proper order, whether the "assembly" option is checked or not
5) shift key does not work in certain webpages and apps when using the physical keyboard
