Just tried it out as I was not able to wait for Android 12 ROMs, and I wanted to experience new 'Material You' design once, so just flashed Pixel Android 12 Beta 5 GSI with PE Latest Vendor.
The installation was quite simple in my opinion. But the finding bug fixes ain't my cup of tea. Better I am leaving them off to the developers.

Now, don't spam me how's Gaming and other things. I didn't test them. And I have started testing Lineage OS 18.1 Android 11 Unofficial.

Quick Update about upcoming review:
I might release Lineage OS 18.1 UNOFFICIAL Review on channel in coming 3-4 days.
Right now my health isn't great, that's why the review is taking some extra time to be completed.

I am waiting for ShapeShift 2.8 but seems like Source side forgot to release it yet (lol). Anyways, if SSOS doesn't come, so will try out PX for some time...

Also, the updates regarding ROMs or Oxygen OS Updates will be posted with device names now.

For e.g
Older post titles used to be:
🆕 Lineage OS 18.1 Android 11 UNOFFICIAL

From now, it will be as:
🆕 Lineage OS 18.1 Android 11 UNOFFICIAL for OnePlus Nord

This is done in order to avoid confusions between users as the posts are shared in different groups having multiple devices as support.

Why the Dot OS Unofficial Build was deleted?
The reasons mentioned by the developer @alwaysangry are as follows:
1. The build was stable with no bugs at all.
2. I deleted it because I wanted to give to the people who are most active in the community and they got it too... ☺️

Sounds like Dot OS Unofficial Build was like limited time grab, which I think some or many people missed it.

Quick Update about upcoming video:
I have cancelled LOS 18.1 Review as it was taking too long to actually test and release it's review. Plus I am suffering from some health issues recently, so I can't speak much for longer time (which is necessary for videos).
However, by next week I will drop a review on channel.
