Both the small maintenance update and larger cumulative update are rolling out OTA
For a company that is largely untested when it comes to providing updates to Android devices, Hisense seems to be looking after its Sero 7 Pro pretty well. Another update, albeit an extremely small one, should be rolling out to nearly all users by now. For those that missed past updates, a cumulative update of 330.6 MB will be available for you to download. For those already on Build number P756.6.02.11.00, the update comes in at a scant 1.7 MB. The latest Build number is now P756.6.02.11.00, with no other obvious software differences in sight.
This update does not change the Android version number, which is still the same one that the Sero 7 Pro had out of the box — Android 4.2.1 Jelly Bean. With Android 4.4 just around the corner, one has to wonder what Hisense's plans are for the future of this tablet's software.
