Design mockup from android central forum
1) 3 type of model variation may be released for their 10th Anniversary product launch for the S series. Both regular size and a larger version will be making its debut which is already familiar to both the Galaxy S8 | S8+ and Galaxy S9 | S9+. The 3rd entry to the S series line-up would be a flat variation for those still prefer a solid grip on the edges of their smartphones.
2) As Galaxy A8s was launched in China market with an introduction of the infinity-o display (pinhole display) forgoing the notch design making it an almost true screen to body ratio,
3) On top of that, built in ultrasonic fingerprint sensor which will also make into the feature of the next flagship series. This would make most space on the rear to have a better camera setup which most likely to have triple camera spec which we have seen on the Galaxy A7 2019.
A plausible rumour on a new gimmick feature of the wireless charging feature called "powershare" did mention around as well.
Stay tuned for more collective leaks around the internet
