There is allot of glitches in this OS. Freezing, stuck on "ending call" screen. Hitting the home button when locked to see if there is a text and the phone won't respond Then I have to reboot the phone. It gets suck on the apple logo for 5 minutes.. UGH... A few other issues but... I can't think of them now.. My phone worked perfectly prior to installing this update.. Now... Its become unreliable. Anyone else????
