Description:
The concise design of the joystick avoids the mobile phone camera and map being blocked in the game.

Features:
1. The game controller trigger is a retractable and reversible front button gesture handle.
2. The game controller trigger can be fixed on the phone reliably and protect your phone well.
3. To better simulate human finger touch data for minimal latency, we apply the mapping to game triggers.
Some phones disconnect or delay:
01. Press the left or right thumb on the screen, then press
02. Turn off the phone screen for 10 seconds and then turn it on again
03. Wear the G21 for 20 seconds and it can be used normally
