QHD resolution (1440x2560) is one of the most popular on the market today. Many people, however, think that QHD is unnecessary, mainly due to a shorter battery life. Samsung listened to people's opinions and company plans to introduce an update for Galaxy S7 and S7 Edge that will allow to change the resolution of your phone.
This option would appear in the Android 7.0 for both of these phones. It is worth noting that the ability to adjust the resolution appeared in Galaxy Note7. There were three options: HD (720x1280), FHD (1080x1920) and QHD (1440x2560), and the same will most likely occur in the S7 and S7 Edge.
