i too was forced to update on my razr hd a couple weeks ago, overall...... not horrible and even a few things i like/dont mind but there are more that just piss me off.
i loved the former unlock screen! left,right,up,down during unlock went to a different function, now you have to unlock and choose. more of an annoying inconvinence.
i only had to reinstall a couple apps, what i did have to do was "throw them away" from the home screen and re drop them from the main app menu.
havent tried the bt yet, but i had to redo the wifes items
GREY SCALE SUCKS! as i use wifi at work all the time and it is in and out due to building design and locations it was nice to glance and see if white or blue = connected or not! now you just guess at it?
dial pad quite different but not horrible
alarm clock is horrible! i use mine as a secondary alarm and before was huge snooze, or vol buttons would snooze, now you have to swipe one way for snooze and the other turns off, as does the vol keys.
as someone mentioned before about the texts, you cannot read last thing said and is harder to tell who said what CAUSE GRAY SCALE SUCKS!
the auto dim is annoyingly quick to dim very low! before you could say hold it in a ray of light to brighten the screen then as long as it wasnt terribly dark, as long as you had decent ambiant light it would stay bright till either the screen shut off you you shut it off. now even with good amebient light if not held directly in the brighter light it dims down quite a bit making it harder to see the screen. i may have to just turn the auto dim off, and adjust it mannualy. ( sucks cause i am in and outside a fair bit and fussing with brighness all the time sucks)
wifi seems like it takes a bit more to connect sometimes, but seems to work decently aside
seems like the touch sensitivity is different now too, there are several things that take more "effort" to do. like you cant swipe something, you have to touch and drag it with pourpuse ..
batt life seems pretty normal maybe like it takes a little longer to charge but nothing hugely noticable
all in all not bad just annoying little things that were mostly taken away that i had before, if i had the choice i would not choose the update! but force updates are what they are i guess.
ok i think i am done ranting now! bastards
