Why fix what isn't broken? I've had nothing but issues after the update. Normally before I go to sleep I put my phone on mute so I don't get notifications in the middle of the night but after the update if your phone is set to mute the alarm will be disabled completely. This has caused me to miss my alarm to be late for work twice already, I took my phone to a Verizon rep and even he couldn't figure out how to get the alarm to sound while on mute either. We also tried installing a third party alarm clock but that did not resolve the issue either, extremely annoying.
The only way to have the alarm sound while under mute is if you click the gear icon after you press the volume button all the way down until it is under the mute option and under "No interruptions (not even alarm)" you select the option under Indefinitely (should be set to 1 hour by default) then set the time for how long No interruptions will occur for. Note that you can only have it set to not interrupt for at least 15 minutes at minimum and you have to set this every single time you go into the mute option.
Also, I liked in the previous version the notification icons that appeared even when the screen is locked in the upper left hand corner of the screen. Now just the text "Verizon Wireless" appears and you have to unlock your phone just to see what type of notification it was that you received. After doing some digging into the settings it appears they removed that feature as well. I've been a loyal Droid user for awhile now and this is by far the worst update I've ever come across, I'm going to have to use my old Droid Razr Maxx as my alarm just to make sure I have a reliable alarm clock, good grief. I'm almost ready to switch to an iPhone.
