Mi Note Pro: Unable To Connect Galaxy Gear S2

Feb 11, 2016
Hi there
I'm using a Mi Note Pro. Rom is 6.4.7, bootloader is unlocked
I'm given a Gear S2 as a gift from my partner. But it is unable to connect with my phone. even both devices are recognized each other via Bluetooth. I tried to connect the watch with my wife' Samsung Galaxy Note 4, and my mother's Sony Xperia Z5, and both phones are pairing well with the watch without any problem.
I think Xiaomi phone is not compatible with Galaxy Gear S2 as it is not supported to be global phone
I did search around google but no help
Hope anybody have the same situation and share your experiences
Thank you
