I bought this tab on 13th may 2016 and the warranty expires on 18th may 2016 which I came to know when I registered my tab in dell support online.There is no warranty card in the box as I have seen in many unboxing videos by reliable tech websites like Tech radar,Tab tech and Fone arena.So think twice before you buy it.Amazon isn't reliable any more.Simply allowing sellers to sell crap without any scrutiny on them.

I bought 3000 series, having 1GB ram and 32GB internal storage. 16GB was available to use. Its simply awesome, windows 10 runs very smooth,battery backup has improved surprisingly. Though its ~189ppi, display quality is awesome, touch response is also awesome.Windows 10 Update guide:1. Search google dell venue 8 pro BIOS update, u will find two updates 6MB and 97MB on dell site, install both.2. With the help of otg attach pen drive to tab, and download windows 10 from microsoft site to pendrive(search media creation tool in google).3. before start of update make sure your battery is recharged full, follow instruction one by one and let it update, update takes around 1-2 hours.I would like to help if anyone required for update or more info.
