When Verizon opts to advise users to hard reset the phone after every major
update, do they realize that individuals use the phones for business data
and apps? I have roughly 700+ apps and associated data on my android and
can not afford top reinstall all the apps every time new major release
there's a program called SnapPea for windows you can use that connects also installs to your phone. ... that will help alot since your not "rooted". If your phone is rooted then of course use Titanium Backup in the play store.
It's recommended you do a hard reset every so often, even without an update at all. That said, major updates do not come that often, and usually about once every six months or so.
Yes to keep your phone and data secure and performing optimally you should get in the habit of backing up and wiping your phone clean often. I do it at least quarterly, and wipe my pc clean once a year.
I know it is troublesome especially when you have a lot of apps like you do, but once you get a system going, it shouldn't take you more than an hour to get you phone cleaned and apps reinstalled. It will eliminate spyware and apps that others may have installed without your permission that spy on you and send your info out.
I'll share my BACKUP REGIMENT. This may work for you, and others may also have ideas on how they quickly rebuild an extensive smart phone like yours. Its a good practice.
