Users in South Korea report that their LG Q6 units have already received Android Oreo and along with the usual features the OS brings, LG has pushed some useful new features as well.
The Q6 now gets DTS:X 3D stereo sound support, camera LED customization - it can now light up for calls, messages and while listening to music. The camera app supports scanning QR codes as well, so there's no need for third-party apps anymore.
The update is rather hefty at around 1,170MB and we don't know when it will hit the other alterations of the devices, namely the Q6+ and the Q6 alpha. Also, there's no info on when Oreo will go global. But since there's a small difference between the Q6 variants and their global counterparts in terms of hardware and UI, we can expect them to be updated shortly.

Very true this is the main reason they lack in their sales in India. The phone is very good at this price but what about the update. Cheap brands in India give Oreo to their devices. Let's wait how long it will take to release Oreo to Q6.
