Review on 💡 GameSir T4 Pro Wireless Game Controller: Dual Shock USB Bluetooth Mobile Phone Gamepad Joystick for Windows 7 8 10 PC/iOS/Android/Switch and Apple Arcade MFi Games with Semi-Transparent LED Backlight. by Tutan Dennard

To connect GameSir T4 Pro to iOS device first, on page 10 of T4 Pro manual:1. Put the T4 into pairing mode by pressing and holding the Home and V buttons at the same time until the controller turns on. The blue lights will flash and T4 will start connecting.2. On your iOS device, make sure Bluetooth is turned on.3. On your iOS device, tap the device name (it will be listed as "XBox Wireless Controller") and pair it. After pairing and powering off the T4, all you have to do is connect it to the same iOS device. Turn on T4 and it will automatically connect to your iOS device. If you later connect T4 to another, second iOS device, T4 may not connect to your original iOS device. In this case, on iOS, on the source device that refuses to pair, go to Bluetooth and tap the little blue i icon next to the XBox controllers list. Then select "Forget this device". You then connect T4 to your iOS device by following the process above (Home + B). Works great. So far I like the T4 Pro Controller. I bought it because I need a controller that is compatible with as many different platforms as possible, and it is.
