Review on GameSir T4 Pro Wireless Bluetooth Controller: Nintendo Switch & More - LED Backlight, Turbo Gamepad, Dual Motor Joystick, Programmable for iPhone/Android/PC by Karen Murray

Let's say you have multiple devices you want to use this with, maybe a phone via Bluetooth and a PC via a dongle. The controller makes this very inconvenient as it forgets all previous pairings when switching modes. Every time you want to use it with your phone after using it with a computer, you have to pair it again by telling your phone to forget the controller and then pairing the same controller again. It's slow and tedious. If only this controller could remember the last successful pairing FOR EACH MODE (like Android, Dongle, iOS and Switch) that would be perfect. Here is my suggestion. How about updating the firmware with the following sequences: D-PAD DOWN + HOME = power on and reconnect to the latest Android device D-PAD LEFT + HOME = power on and reconnect to the latest 2.4G dongle connect D-PAD UP + HOME = turn on and reconnect to the last switch D-PAD RIGHT + HOME = turn on and reconnect to the last iOS device. This firmware modification will likely be easy to implement and will make the controller much more convenient for those who want to use the same controller with multiple devices.
