Hello, I was wondering if I could keep using my S3 by cleaning up the storage (eg deleting many useless things) and use a legacy operating system and apps that were initially design for the S3. As my phone currently auto updates, I believe the updates are not designed to run on my phone. Is there a step by step process I can perform to clean up and speed up my S3 so I can keep using it and not have to trash it cause it's "old"? Thanks. rwa
