With little fanfare — or perhaps the fanfare has yet to ramp up — Chuwi has released a firmware upgrade for its various models of the Chuwi V88.
The firmware download page is here [Google English].
Note that there is more than one model of the Chuwi V88. Be sure to download the correct firmware for that model. If the model you have lacks Bluetooth, don’t download the firmware for Bluetooth or you could brick your tablet.
I don’t know if this will also be an Over The Air update, but that would make sense, so check Notifications for the update.
This firmware update will bring to the Chuwi V88 the same 4.2.2 features the Onda V818 has had for the past few weeks. One notable improvement should be to WiFi connectivity.
Don’t expect any Chuwi V88 you order now to include 4.2.2. Vendor inventories likely have Android 4.1.
