AOSP improves the Honor 9 Lite in a number of different ways. The Honor 9 Lite, as time went on, was unbearable in terms of performance, as I touched on in my review. With AOSP, it tells a very different story. The device is fluid, it’s quick, and it’s extremely responsive. It blows EMUI out of the water in just about every metric. If what you’re after is features, then you can even install a Resurrection Remix or LineageOS ROM instead of AOSP. If you don’t care about camera quality that much, then I fully recommend ditching EMUI. Even then, the camera issues may eventually be fixed with time. But it does leave one question: What on Earth happened to EMUI?
I can’t tell why AOSP on this device is just so much better than EMUI. It’s fluid, it’s fast, and it’s everything that EMUI is not. It could be the lack of bloat slowing down the device. An interesting fact is that I could not work on articles on my phone on EMUI as Chrome would simply crash, but other than the occasional lag spikes on AOSP I was able to edit and work on articles to my heart’s content. It just felt so much nicer to use. That’s not something you can pick up on synthetic benchmarks either: it’s something you’d have to try yourself. If you have an Honor 9 Lite with EMUI and you don’t mind losing out on camera quality then I highly recommend switching over to an AOSP-based ROM
