Why upgrade to Android 6?

But there you can generate a full backup e.g. with Acronis and a simple boot recovery.

Not so easy with Android as I could read. It surely would need more steps than on any conventional computer I believe.

A full dic:backup of your Android phone is very easy if you install a different recovery beforehand (like TWRP or CWM). Unfortunately the preinstalled (aka “stock”) recovery is not capable of doing a full backup image.

Note that “recovery” in Android-language might be used differently than in PC language. I personally would compare it to BIOS. Read more here: dic:recoverymode.

Many users asked for a Marshmallow update again believing in miracles to have every issue with Lollipop solved…wrong expectations again. This is not the way operating systems work. It is not a simple (incremental) update, but nearly a system change. Yes the expression “update” does not always has the same meaning.

I would probably use “upgrade” for a major version change like from Android 5.1 to Android 6, and use “update” only for the monthly patches. Wikipedia uses a similar terminology:

A major upgrade will change the version number, whereas a minor update will often append a “.01”, “.02”, “.03”, etc.
