Default [Q] Bluetooth tethering very slow on HTC One

Hi guys,

I bought a device that can only connect to internet using the internet connection of a smart phone or a device that support bluetooth tethering.

If I enable the bluetooth tethering on Samsung Galaxy S4 and connect my device to it the speed is more than great ! But if I connect my device to HTC One the connection speed is horrible. So this concludes that the issue is not in the device but in the HTC One it self, I guess?

Does anyone know if I can improve the speed quality somehow? On the device I cannot install any software so the only way I see is to somehow fix it in the HTC One.

Let me know if you guys have notice such an issue with the HTC One.

Thanks
Vlad
