Magcubic HY300 & HY320 Debloat, Malware Removal & Launcher Setup (2026 Guide)
Sub-$60 portable Android projectors like the Magcubic HY300, HY320, and similar Allwinner/Rockchip devices offer great budget projection. However, security researchers discovered pre-installed residential proxy ware (Hotack silentsdk) and heavy telemetry services that severely lag down the 1GB RAM hardware. Here is how to clean and optimize your projector safely.
Why You Must Disable "Hotack Silent SDK"
The package com.hotack.silentsdk runs in the background 24/7 without user knowledge, relaying unknown external web traffic through your home Wi-Fi network. Disabling it immediately restores bandwidth and frees up 150MB+ of precious RAM.
Enable Developer Options on Magcubic Projectors
- On your projector, click the Settings icon.
- Navigate to Device Info / About.
- Find the Build Number and click it 7 times with your remote.
- Go into Developer Options and toggle USB / Network Debugging ON.
- Note your projector's local IP address (e.g.
192.168.1.120).

Install Projectivy Launcher (Massive UI Speed Boost)
The stock Hotack launcher drops frames and stutters heavily because of 1GB RAM limitations. Replacing it with Projectivy Launcher cuts UI latency in half:
- Install Projectivy Launcher from the TV App Store or sideload via USB.
- Assign Projectivy as default Home:
adb shell cmd role add-role-holder --user 0 android.app.role.HOME com.spocky.projengmenu
- Disable the stock launcher:
adb shell pm disable-user --user 0 com.htc.magcubicos
How to Switch to HDMI Input Directly
After switching to a custom launcher, you can jump directly to the physical HDMI port (for PS5, Xbox, Switch, or PC) using this intent command:
adb shell am start -n com.softwinner.awlivetv/.MainActivity
You can also add this shortcut directly inside Projectivy Launcher under "Custom Shortcuts" for 1-click access with your remote.
