If you are looking for a Bluetooth game controller with PS4-like triggers and bumpers, check out the Gamesir G3s!
The Gamesir G3s is a 32 Bit microchip game controller with rapid response time. It has three types of connections: 2.4GHz wireless connection, Bluetooth 4.0, and wired connection.
Gamesir G3s is compatible with Apple devices, Android devices, PC, Amazon TV, Apple TV 4th GEN, MAC, iPad, iPod, PlayStation 3 and even Android TV boxes.
I tested the GameSir G3s with the UGOOS UT4, Droidbox t8-Plus and Probox2 Z media player TV boxes and works fine.
There is a built-in lithium battery which takes only 2 hours to charge and gives you around 17 hours of battery life.
The game controller mount holds a smartphone securely in place thanks to a spring loaded bracket.
The controller mount fits phones around 3 inches wide and the tilt can also be adjusted via two tightening screws.
The bottom side of the GameSir controller features light indicators that tell you whether you are hooked to Android, Apple, mouse (which can be PC or Android TV box) or wired connection.
The controller itself has two analog joysticks, responsive D-pad, Select button, Turbo button, REset button (located on the backside), Clear button, Start button, micro USB port, Left and Right Bumpers, Left and Right Triggers and four gamepad buttons (X,Y, A, B).
