I have to say this is a nice build, and as others have said, it does have a few bugs but the most important thing for me is the fact @michie has made it a painless build w. enough gAPPs to avoid trying to find a compatible gAPP set AND security fixes. It is the latter that frustrates me with Google and other Android phone/tablets that you can't even get OTA security fixes. The fact I have an iPhone 6s Plus that still gets security fixes & is on the latest iOS 15.5 says a lot for Apple's commitment to their ecosystem. Google not so much as they continue to introduce and then drop products, sometimes in only a couple of years. The Pixel C screen compares well to my iPad Pro M1 10" & is far crisper than my MS Surface Go 2. Even than, NVIDIA TX1 is still relevant since it performs well with my NVIDIA Shield TV that I purchased in 2015. So well that I have three of them since their really isn't anything that comes close (Apple TV 4K maybe if you want to pay more & be limited to the wall garden). There is also the Nintendo Switch that is still going strong on the TX1+.

As a developer myself, one of the problems with Google TX1 variant Pixel C, is that they didn't even license NVIDIA's GPU drivers which showed in Shield TV - Pixel C comparison benchmarks by using an open source (reverse engineered) kernel from Nouveau.

Anyone looking into the NVIDIA's open source Linux drivers recently announced? I for one think it is probably not worth the time on seven year old tablet, but if someone did try it, I would be happy to test your build.

Thanks for this ROM, it works well. What's with the pixel light bar on the back though, it's going mad, flashing like crazy, going on at totally random times even when the screen is on or off?

Switching between apps causes the other app to redraw 95% of the time sadly. Does this need a zram tweak?

I did flash the Unified Kernel however as that fixes the CPU slowdown that Google programmed in with battery age.

As performance degraded too heavily on pixel experience I decided to end development. I recently started testing Arrow OS which provides a fast clean custom AOSP rom for our device. I will open a new thread for anyone who is interested.
While I loved pixel experience for the simplicity and delicious pixelness, you're right, it's super slow. Decent for videos and playing a couple games but even Plex is laggy in it. Looking forward to your next adventure!

Sweet, thanks for your hard work, I look forward to trying it. It's much easier with the tablet to change ROMs, no banking apps etc :).
