It's catered to the average Malaysian internet speed. Honestly tho other than the 25FPS frame rate, the quality is not that bad. Just a bit lower quality than Astro Go (which sadly also is streamed at 25FPS, which makes sports looks like slide show). In the end, I still rather use the white STB that utilised the dedicated VLAN600 for UnifiTV, rather than use the app

Kinda. But then again that white STB is quite old. Hence I only use it for UnifiTV and never actually use any of the other features (iflix or anything else). I wish there is a replacement for it, but the black UPB is solely IPTV instead of using the dedicated VLAN

that white STB was very smooth before they decided to revamp the UI. 
the previous UI was basic like, but very responsive, smooth changing channels.. even got small PIP mode, channel reminder setting.

the new UI is shit lag, slow response. even the PIP and channel reminder also gone missing. 

I manually updated my box to the latest update. Biggest mistake.

Before the update I was able to enable developer tools and enable USB debugging so that I can use adb to sideload apps into the plus box. Steps taken from here: https://androidrepublica.com/2020/03/cara-i...unifi-plus-box/

I had everything I needed for my setup:
- Cloudflare WARP
- Disney+ (not hotstar)
- Peacock
- Paramount+
- Netflix mobile version (because the plus box can't open the default Netflix app)
- HBO Max

After the update, I noticed it wouldn't connect to WiFi. I traced the problem to an incorrect date/time setting on the box. Today is 1st Sept but for some reason after the update the date went all the way back to Jan 25th. I couldn't change the date too because it's greyed out.

I resorted to factory resetting the device, which was a big mistake. Aside from removing all my sideloaded apps, the reset did fix the date and time problem, but still couldn't connect to WiFi. So I just switch to LAN. That's when I discovered that any attempts to enable USB debugging on the Unifi Plus Box would be greeted by a password prompt which I do not have. Before the update, USB debugging can be enabled without any prompts for password.

I think the firmware update is to prevent users from sideloading apps into the box. Luckily I have an unopened box of Chromecast with Google TV sitting around. The Unifi Plus Box is going back into its box and will be replaced by the Chromecast.

make sure you don't factory reset it hahaha
