Yes, I have the same issue and a few more. (stock phone) I am a minimal user, less than 1 gig of data a month.
Battery life is approx 1/4 of what it was; went from 2 days to 1/2 day. :'(
WiFi turns itself off and reception is horrible. My router is within 10 ft. and yes I have checked it. Laptop signal is still strong.
Blu-tooth will shut itself off sporadically
Auto screen rotate - turns itself off every single day!
Phone will not always shut down on first attempt
Phone signal is horrible. Used to have 4G LTE most of the time, now I'm on a 3G most of the time or down to 1X at home. I drop more calls now than I ever have since I moved to the Ann Arbor area.
BATTERY life is horrible ..... :'(
Lost the packaged calendar, finally got it reset after a week of messing with it and it is working again....
Lost every setting I had.
Lost the ring tones I had added
Can't seem to get notifications working right yet. Phone won't ring sometimes, or text notification doesn't vibrate when it's set to vibrate.
battery life is terrible :'(
Apps don't quit anymore, I have to back all the way out of them. that is a major P I the A.
or
I get the message that app (x) has unfortunately stopped working.
and
Battery life still sucks!
Yes, my phone is faster.....that's it. I have noticed no additional enhancements. I have uninstalled or disabled most of the new apps that were added, I don't need or want them. I have cleaned the partition. I have not reset the phone and until someone can prove it is worth all of the hassle, not going to....
