[Xiaomi Mi A2 Lite Guides, News, & Discussion] TeoXSD:
First of all, I changed my logic in which I do this updates. Last month I had my one and only random system reboot so I tried to give it a little thought on how I should update this system, and so far I had no problem with it: You see, Android 10 had quite a lot of bad, unresolved updates, especially for those who manage to have a "successful" day one update (this translates to those who didn't have a bricked device) so now, when an update comes, it just tried to patch the old broken version, with mixed results, and not completely over write it. Remember back in A9 age? When you'd miss an montly update, the next month your update size would be >1gb? That means the 2 version old android version wouldn't be compatible with the new build so it did a complete rewrite of the partition? This never happened on A10 since launch, so here's what I did, after that system crash I downloaded the 10.0.7 and flashed it twice (by rewriting twice it means this, flash, reboot, boot into system, shut down, recovery, flash again, reboot, boot into system) through recovery, thus rewriting both A and B partitions with a known "good" (it still has bugs, but it doesn't carry the day 1 or day 2 major bugs) firmware flash. Now the same happened with the new update the 11.0.9, copied to SD, flashed through recovery and here is my review.

The bug in which the 5G icon in the wi-fi menu wouldn't hold if connected to the network and turned into a 4G wi-fi network still stands. This is only a visual bug, since the 5G network is doing just fine.

Tested the camera extensively and now it has a more aggressive focus and it's sharp again, image size is now large, like before, quality is improved in daylight, but the low light still could use some improvement.

The "useless" cards in Settings menu are still there (I personally only have the Customize your pixel one).

There is now a smoother feedback in the haptic feedback, so sometimes it seems like it's not working, but it's me not feeling it.

The 4G speeds still seem to be low, but again, like I said last time it could be a problem from my network provider, so I can't be 100% sure.

The internal storage speeds seem more and more slow on the other hand, I can't get transfers over 30mb/s on the internal storage, weird, because on .7 I could go over 100mb/s without a problem.

The RAM management is weird, after flashing the phone "my way", I can open ALL of the phone's apps and they'd stay up and running in the RAM until the phone starts going so sluggish that's almost a burden to use. It doesn't selectively remove apps from ram until closed from the recent menu. It isn't a problem for 5-10 apps open at once, but it starts getting weird after 30-40. Also the background apps are killed after a specific time, not by RAM usage which is counter intuitive... damn.

The MTP - SD card is still faulty. Refuses to display contents of large folders unless plugged out and plugged back in again. At least it's not crashing transfers right now.

The Media scanner is still faulty, after copying data to SD card they won't display in the specific apps (Google Photos, Google Music) but if manually searched (for example in my case Hiby Music) they're there and they can be used. Only reboot fixes this problem.

Direct Share is still not working.

This is all I had to say about the new .9 update, the rest of the more extensive things I covered can be found in the 11.0.7 thread, and it wasn't productive to write them here again, since the experience didn't change.

Battery seems a little worse than 11.0.7 but that was just the first day of testing, so it's irrelevant for most real world situations.

Other than the new method of installing and the few problems that seems odd to me, I can't report anything else after 1 day of usage. It's more usable, but it still have it's quirks... at least they didn't break anything else this time.
