A new tablet (possibly Nexus 7 successor) was spotted by one Twitter user Cesi D’Alessio in the official Hangouts promo video released by Google. If you go to 21 sec mark in the video, you will see a tablet with notification LED. From the looks of it, the tablet seems to be packing a 7-inch display and the current Nexus 7 tablet from Google does not have notification LED, so can this be the next Nexus 7 tablet?
May be or maybe not. You can also get a glance of its back later in the video, but not much is shown, which is possible if it is an unannounced device.
