Xperia Z4 Tablet

                                                               Xperia Z4 Tablet

The new Sony Xperia Z4 Tablet facing a super fighting above world tablet market.  The Xperia Z4 smartphone is just an elaborate update limited to the Japanese market. The 10.1 inches  tablet  has attractive styling and razor-thin profile.

The Xperia  Z4 Tablet stands on the virtues of the Xperia Z2 Tablet from a year ago.  It has low 224 PPI of the predecessor, we're happy to note that the tablet's display resolution has been brought up to date ( 2,560 x 1,600 ) pixels.

Perhaps most important thing is an IP68 certification means you can submerge it in water  up to 30 min and 1.5 m in depth, without any thinking for its lifetime.

 Besides It's weights just 393 gm.Meanwhile, battery capacity hasn't been sacrificed and has remained at 6,000 mAh, but will that be enough to power 80% percent more pixels and more capable chipset?
