I write this post because I am sick and tired to bash the Mi box and Android TV OS. Thank God an inexpensive full Android TV experience with Google Assistant on all my house and personal office rooms at 1/3 price of Shield and Apple TV. I have a Nexus Player, Nvidia Shield TV and 4 Mi boxes. Nexus Player at Android 6 was decent fast. At Oreo I have the fastest Assistant but the navigation is sluggish and app launching is slow. I disabled the window and transition animations to 0x, set animator to 0.5x and it's passable now. Nvidia Shield was always fast but it's an overkill and it had their own problems. Let's continue to Mi boxes. They were fast at 6.0 without any problem for me. But the Android TV 6 was the phone Android with the custom launcher Leanback. It's oversimplification I know. If you looked at the system many components that took ram and CPU resources were useless for the TV experience. Android TV 8.0 is a real streamlined version for TV and it broke in pieces to core components to be updatable through Google Play Store. Finally! After the update on all of my devices the performance is faster on booting, launching apps, navigation and playing videos. Specifically on Mi boxes after boot on 6.0 I had 350-550mb of RAM available. I update to new OS on top of old and on first boot I have 900mb RAM and ~1GB of internal storage freed. So the new OS is lighter. Also days after the update launching apps without reboot or memory optimizer apps etc I have constantly 600-800mb RAM. Clearly it cleans up memory automatically at idle. But the ram management is way better than 6.0. At 6.0 2-3 apps the next was relaunching. The leanback was a disaster and the new homescreen is now faster and take less space and ram. I have 14 channels at homescreen (video and audio homescreen autoplay disabled) and I have 53 apps installed. Again available memory 700mb, at Nexus Player 250mb... I have set to 0x window and transition animations and animator to 0.5x to get even faster navigation without any lag. Also 8.0 behaves much better if you want to disable some animations. At 6.0 disabled animations especially on leanback launcher create problems and dropped frames. It is not a change of need but for speed. At 6.0 I had sporadically dropped 5-10 frames on 4K 60p on Youtube if I skipped too fast videos. Now a nice round 0. HDMI CEC is usable now. I have installed all apps on USB sticks. At 6.0 the app that was moved at USB stick was noticable slower. Now its almost like launching from internal. The set up process streamlined and it is faster. Also the format to adoptable storage and moving apps between internal and external difference in speed is huge. The same with app downloading and installation. I have very good 64GB USB sticks, huge USB, believe me guys. I have paired Sony Bluetooth headphones at bedroom and living room without any problem. But I think the Bluetooth audio could be louder. Also at kitchen it paired with 2 JBL Clip 2 for music at backyard. Now let's talk about the problems. After the last update if they are sleeping more than 8 hours they lose connection with the remote and you cannot wake them up. The HDMI CEC wake the living room Mi box always but the HDMI CEC at kitchen sometimes. So no HDMI CEC enabled out of luck. But I find a solution. They transmit Bluetooth signal and they are connected to Chromecast and WiFi while sleeping. If you go to Bluetooth settings on your phone and you are in range of the device you can find it under Bluetooth devices with the name you gave like dining room, playroom etc. The phone tries to pair and failed. After second or third attempt the Mi box wakes and the remote is connected. The whole process takes me 1 min. So no reboot for me. Also Google Assistant understand me what I said exactly but sometimes Google sanitaze it to another similar phrase. It's frustrating but constant Google updates for the last 3 months improve the situation. For the last I am not sure maybe it's a placebo. Also after waking sometimes Assistant is sluggish. On 6.0 I had sideloaded Assistant on Mi box and it was super fast. So problems with Bluetooth remote on all 4 devices. I was since 1998 through 2016 an exclusive Apple products user. I transition to Google ecosystem and I amazed with the everyday innovation and little tweaks on apps and services. Changes that take Apple months and years. For justice I tired to hear complains for the Android and to hear how much stable is Apple OS. I transitioned as an experiment and I was expecting a hell of instability and problems. I recognize that I change in a good era for the Android OS and my first interaction was 7.0 and above. Also my Wear OS journey is horrible. But Android phone, tablet, TV, smart speakers, Assistant and Chrome OS experience is superb.
