========================================
Though the smartphone is able to locate and pair with another Bluetooth devices, it lost connection after a few seconds. The smartphone keeps trying to connect several times while the paired mode is enabled. I tried to connect it with my notebook, my earbuds, my tablet, my second PC, Chromecast and SmarTV but the same thing happened with all devices.
