LG G7 ThinQ confirmed to receive Android 9 Pie update in Q1 20192
Just like it did with many of its previous flagships, LG has only made its G7 ThinQ beta program available in South Korea, at least in the beginning. More recently, the handset maker confirmed that the final version of the update will be available for LG G7 ThinQ owners in South Korea in Q1 2019.
We know the timeframe is a bit vague and that it only contains information about a single market, but it's better than not having any information about one of LG's flagships launched this year.
However, we can be sure that once LG starts rolling out Android 9 Pie to the G7 ThinQ, it won't take too long for the update to arrive in other countries, so stay tuned for more info on the matter.
