Android 4.2.2 for the Onda V818 could roll out today.
There’s a downloadable RAR file for 4.2.2 for their V972 tablet.
I haven’t yet seen a link for the V818. When I do, I will update this post.
I’m very interested to see this update and if it changes the customized-by-Onda Settings UI. I’d also like to see new AnTuTu scores.
After the break, I’m repeating the video from AllWinner that shows their 4.2.2 update running on the Onda V818.
Same-day update: This 4.2.2 rollout is over the next week and is a public beta. It’s probably best to wait for the final firmware to show up at the Onda download page or to get the OTA notification.
