Which phone do you have? On most android phones if you clear the cache partition after you get an update it clears out all the old files that maybe conflicting with the new ones. Depending on the phone you have on my phone I do the hold the power-volume up-home to get to the recovery mode then just use the volume key to go to clear cache partition- then power then volume down to say yes and do the power button again. When you clear the cache partition it does not mess up your settings on the phone.
