Sound is loud and clear, in call sound is also great. I did not find any issues with 4G LTE and the network, WiFi, GPS and Bluetooth worked well.
This handset also comes with categorized notification – priority, utility and social you can assign apps in any of these categories.
S-Bike mode is supported, though there is no NFC you can enable this mode by holding the power button for few seconds – you will then get the power off, restart and S-Bike mode there.
