I was so happy to receive the 2.2 update, but i got the following:
slow start and shutdown
constant random rebooting
battery felt hot most of the time
battery drained faster and took longer to charge
apps crashed like crazy
a bunch of bloatware running in the background
sometimes the phone would get stuck rebooting over and over
i was ready to throw this phone out the window...even jump over to another carrier, thats how mad i was.
then i decided to do a factory reset...
and everything has been great ever since.
the phone is back to how it was before...functional and reliable....with the benefits of froyo....
startup time is as it was before, quick
no more app crashes,
and to stop the stocks and news apps from constantly launching, i went in to the sync settings and turned them off...
battery time is back to what it was before froyo [which wasnt that great but hey..]
it's sad i had to go through all that nonsense just to get it working but i'm glad i did the factory reset.
