Any "must have" applications from Google Play for the M6 PRO?

[GeorgeKa]

Hello,
I just bought the new Pipo M6 Pro 3G and as I am waiting it to arrive from China I was wondering
if there are any "must have" applications that I can download from Google Play in order
to improve some of the tablet's functions.

I am talking about utilities and programs that can replace the ones built in the tablet's system
like picture and video viewers, keyboard functions, camera utilities, sound improvement, text and pdf readers etc.

I also want to buy a nice case . preferably with the Pipo logo on it. Can you suggest anything?

Titanium backup is absolutely the most important: with that you can restore your apps/data/settings every time you install a new or modified firmware
