I don't know if this is possible but it would be nice if the final part of any update was the clearing of device cache.
Many of the problems people are experiencing could be solved by manually doing this process. It would save a lot of time if this process were automatic during an update.
Since there are redundancies that cause a host of issues that are caused by old cache, it would make it easier for the software people at Sammy to focus on real glitches. Just seems like common sense.
Yea, this would help a good amount of people who know nothing about cache and all the background stuff in phones. It's better for the system to take care of those things during an update.
