Samsung already announced new 48 mega-pixel and 64 mega-pixel camera sensors, so it's possible that the company will use one of them for the Galaxy S11. However, now the company has announced new 108 mega-pixel sensor which is the one rumoured to debut in the Galaxy S11. According to Techradar, the Samsung Galaxy S11 will apparently also have a lens with 5x optical zoom. As far as front facing camera is concerned, the company is also testing out different setups including in-display camera. It would be a real test for the company to remove the bezels on the smartphone. So it is very likely that the company would be planning to use to build cameras into the screen. According to The Elec (a South Korean tech news site), Samsung Galaxy S11 or Samsung Galaxy Fold 2 might be the first Samsung phone with this feature. There is also a possibility that company may keep the bezel in S11 and remove it later in the devices which are scheduled to be unveiled in the third quarter of the year. It makes sense that the Galaxy S11 is scheduled to be unveiled between February and March. So it would be too early for this type of in-display camera.
