what is with this stock android? the more i use the phone the more i see the inconveniences that come with it..

my latest, at work i saw that my phone had an update available (great). i get home, reset my phone, and now the update that was ready is now gone, and it wont find it if i check manually.

with all my previous devices, the update would always be there even after a reset.

has anyone else had the same thing happen?
and does anyone have a solution to this?

im aware of this thread, but i rather but not force it.
