    Hi guys, I have had my mi note 2 for a few months, and I love it, but the system performance on MIUI 9 from xiaomi.eu is just terrible. I've tried downgrading to Miui 8, and everything worked flawlessly, absolutely smoothly and perfectly. However on MIUI 9 the phone is laggy, unresponsive, slow and buggy. It doesnt affect performance, as the Antutu scores are fine. Updating to Oreo made no difference.

    Thanks for any help

    I am seeing the same issues. Nothing extreme, but the phone is a little laggy sometimes and I see stuttering. This should but be happening with these specs

    I see lag after the initial boot up. It's especially visible when you try to swipe up to unlock and then enter your PIN. Using version 8.3.29 with Android 8.0 on my Mi Note 2.

    I think initial bootup lag is expected or normal. Maybe for 1-2 minutes, until the boot completes. I am complaining about stuttering in normal use during the day.

    I am not so sure, to be honest. The reason I say that is that when I used the official Global Developer ROM for my device the lag wasn't there or was much shorter...

    I've just updated my wife's new Mi Note 2 to 8.3.29 Android 8, and it is working amazingly well.
    While I've still got it in my hands I'll run some benchmarks, just did 3DMarks Slingshot Extreme.

    The screen does better in this game-like use than in normal browsing, subjectively.

    It got 2108 on the OpenGL ES 3.1 test, which is better than 76% of all Mi Note 2s tested.

    However it got 1485 on the Vulkan test, which is only better than 15% of all Mi Note 2s tested.

    They do say at the start that the Vulkan test can give a poor result because of "unoptimized drivers".

    Now I'm not a gamer, 3DMark is supposedly "the gamers benchmark", and I do not know what "Vulkan" is.
    I did know something about OpenGL, but that was long ago and far away.

    Now on to Antutu . . .

    Vulkan is kind of the successor to OpenGL these days :)

    Heh-he! Now I would guess that the poor result on Vulkan is something that Xiaomi.cn will have to work at, not Xiaomi.eu.

    I did not run the 3DMark test on the Mi Note 2 when it was still running official Global Developer, or Xiaomi.eu 8.3.26 android 7, unfortunately, so I can't compare.
    But I did run Antutu when it was still on Global Developer, so we shall see . . .

    Can someone running weekly 8.3.29 Oreo confirm (or deny) that bluetooth cannot be turned on?

    Otherwise this ROM is running very well for me, no problems att all.

    The Antutu score was about the same as before Oreo, and in line with the average for the modell, so no surprises there.

    Well, I never tried Bluetooth before Oreo, so I don't know if I've got a faulty phone or a faulty Oreo installation.

    The feel of it is that it is a software problem.
    So I'll probably try flashing an official Xiaomi rom first to check.

    Should make it clear if it's hw or sw.

    I can't believe you never used BT. Must be the only mobile phone user on the planet like that ;)

    This is an entirely new phone, just got it a few days ago, and it's for my wife. Haven't gotten around to testing everything yet.

    Solved!

    I decided to first try reflashing the EU weekly 8.3.29, without doing anything more drastic at all, and that did it.

    Now Bluetooth works, everything else seems to still work - simcard, wifi, all sensors, all my apps and settings intact apparently.

    Remains to thoroughly test everything again.

    Also have lags and stutters on Oreo weeklies. YouTube often stutters badly.

    Phone slow to a crawl often and sometimes get incredibly hot. Rebooting fixes this temporarily.
