If you have read any tech sites, including Android Police, you probably know how common product leaks are. There was almost nothing new about the Google Pixel when it was finally announced, due to months of continuous leaks. Intentional leaks are often used by companies to generate hype, as is likely the case for the LG G6.
Be wary of fake “leaks,” especially from Twitter accounts like @VenyaGeskin1 was written by the awesome team at Android Police.
