These tablets and smartphones download updates automatically. You don't appear to have much choice in the matter.

I'm a relatively newcomer to Android devices. I don't have a phone and at the moment I only have one tablet, with another larger one on its way. The one tablet I do have has never updated the OS(and I am sure there have been plenty of updates in the year plus that I've had it) so I would have thought there would be some way of turning off automatic updates - although, as a fairly new user, I'm not positive about that and I've never investigated the possibility (maybe I should ). If it can't be done, then that is a definite flaw in the system.

As for not tampering with systems that work, are you using the latest version of mobile sheets or some ancient version that worked so you never upgraded since?

I'm an even newer user of MS, the only version I have ever used is the current one. As I'm not using it in a 'live' situation yet (that's what the new tablet is for) I'm happy to upgrade, as long as there are things in the upgrade that I want or need. That said, it pretty much does what I need as it is.

When I do go live with it, as long as it works, then I certainly would not do any sort of upgrade on the software and hardware that is in daily use. At the very least, I would fire up another tablet and play around first, to ensure that it would not break the working system - should I even decide the upgrade was worth installing. Basically, if it does what I want now, I see little need to take the risk, but that depends on what changes are in the pipeline.

Going back to the previous version of android requires far more expertise than I have. In fact, it looks to be quite a difficult procedure if even possible for non gurus.

Not knowing that much about Android, I can't comment on that. However, the renaming of the iffy file looks to be no more difficult than it would be with a Windows or Mac machine.
