I’m a mi box user in US and have a direct communication channel to Xiaomi Mi Box’s engineers. I will do my best to bridge the users here who have troubles with Oreo firmware with the dev team. Please let this thread be drama free.
Whenever I have new conversations with the devs, I will update here. They include but are not limited to what the devs are working on, which bugs were fixed and which bugs were discovered (by users in the comments). Keep in mind it is very hard to fix a bug if the dev can't reproduce it, so if you are providing new bugs, please be as detailed as possible. I have helped them fixed several bugs so far, I think the key is very detailed reproducing steps.
Update 11/06:
- The auto frame rate switching is top priority now. They already noticed wrxtasy’s hint, but fix is not trivial. Kernel fix is easy but a lot of modules in Android framework and Android hardware layers need to be changed. They also need to work with Amlogic on this so a lot of things are not in their control. This fix will not be included in the current OTA4 update, but likely in next OTA5
- Android P is planned with google! Development scheduled to start end of this year (likely). I think they are a bit short of hands since they also have Mi Box S to work with, but they did not give up this box.
- Please join https://www.facebook.com/groups/mibox/ the devs are there. It already has 7k users. I also introduced this place to the devs, hopefully in the future, the problem posted here is likely getting through.
Update 11/07: OTA4 RC2 is out for beta testers
Update 11/08: It looks like the OTA is approved by google and now everyone has received it.
Oreo OTA4 (2396) Fixed the following issues:
- when mi box wakes up from sleep, the user specified resolution such as 4k@60 might change to 480p or other low resolution.
- When user changes refresh rate in settings, it only changes display refresh rate, but system still think it is under the original refresh rate, resulting multiple apps misbehave, including Kodi. Kodi won’t play 1080p@24 video smoothly if user switches to 24fps in settings, unless reboot.
- WiFi stability.
- Google assistant recognition quality
The devs are testing the DD+ dropout issue but they can't reproduce it. I reproduced it on my soundbar, I may spend sometime to help this weekend.
If anyone still have the mibox won't wake up issue in the latest build 2396 after reset , please leave comments. I don't think this issue has been passed on yet, and it is really hard to reproduce. I had it a few times on 2303 and 2179, but none in recent month. Then again I'm using an IR remote to wake the box up.
Update 11/10
People who has won’t wake up after sleep issue, please do me a favor:
- Install “Mi Remote” app and connect with the box. Next time when you are having wake up issue, try if the app can wake the box up.
- Tell me your network environment. Such as WiFi 2.4G/5G and channel number, having Bluetooth speaker/headphone connected or not.
Update 11/12
A test build to fix the wake up issue is prepared by the devs. Will collect a few serial numbers from the comments to do the targeted test.
Update 11/16
test build sent to a few testers who has the issue and passed SN to me. Let's wait and see their feedback.
Update 11/18
According to the feedback of testers, build 2405 does fix the wake up issue, will inform the dev to push the build to beta test and then public.
Devs also fixed some DD+ issues, but the dropout issue on Netflix and amazon is not fixed. They still cannot reproduce the issue. They are using Yamaha AVR as a test device.
Devs have addressed a issue from user regarding no 4K playback on Netflix. Netflix has provided the following information to the users: When the device resolution is equal or below 4K@30hz, Netflix will not supply 4K video. It is only supplied above 4k@50hz
Update 11/28
I have been busy and can only check my Mi Box once in a few days. A few bugs got delayed in report, so please use the FB group, and if you are a beta tester, use:

I noticed if the box has been off a few days, it won't wake up (2415 build), reported to the devs :(
I have been plagued by the won't wake up issue. I updated my Mi Box last night, so I should know fairly soon if it is fixed or not.
Edit: it powered on after being in standby all day with a single press of the power button on the remote. I'm not calling this fixed yet, but I honestly don't remember when the last time it did that was. Slightly hopeful right now.
Edit2: Hope has been crushed. Woke up this morning, Mi Box locked up. No amount of power or back button mashing would wake it up. Had to pull power. Unreal they still haven't figured this out.
