Samsung seems to be on a bit of an update spree lately, trying to get its devices up to speed on Android 4.2. This time it's the LTE Galaxy Note 8.0 and the somewhat older Galaxy Tab 2 7.0 with 3G. Attacking the system update button like an enraged jungle cat won't do any good, folks. These updates are rolling out in stages.
The Note 8.0 update is starting in the UK, with expansions to more countries soon.
