If the "new" LG Q9 One seems to have an outdated processor, the reality might surprise you: this handset is a rebranded LG G7 One, which was unveiled at IFA 2018. The only noticeable difference is that the Q9 One comes loaded with Android 9.0 Pie out of the box (the G7 One arrived with Android 8.1 Oreo onboard).
