Bad response from Bluetooth Keyboard/Touchpad

[Dannyel]

Hi everyone,

I have a mini bluetooth keyboard with built-in touchpad,

https://www.amazon.com/gp/product/B00BALK9CM/ref=od_aui_detailpages02?ie=UTF8&psc=1

that I purchase with the purpose of remote control my computer using my tablet (Xperia Z2 Tablet, bluetooth v4.0, A2DP, aptX) and this tiny keyboard. It turns out that keyboard does not work as expected, keys are repeated (which could be solved with external keyboard helper app) but the touchpad is very unresponsive. I paired this keyboard to my Samsung Galaxy S7 (bluetooth v4.2, A2DP, LE, aptX) and it is working perfectly, I tried with a Sony Xperia Z3 compact (bluetooth v4.0, A2DP, LE, aptX) and the touchpad remains very laggy and unusable. All these devices are running Android 6.0.1.

I wonder if there is an issue with the bluetooth version (4.2 vs 4.0) or it is just another hidden problem with Xperia phone/tablet. Tablet has been factory reset and nothing has changed. Any suggestions please?

Cheers,

Daniel.

As this keyboard isn't manufactured by Sony the compatibility might not be guaranteed.  Have you tried contacting the manufacturer of the keyboard for troubleshooting?

Hi nolramlb, thanks for your answer, I will check that inmediately!

Only complains about Sony phones (Z1/Z3) and surround system. I think I'm in a dead end with this...
