The Samsung Galaxy S6 has not been around all that long, but the Galaxy S7 might already be in its planning stages, Tech Radar reports.

The Galaxy S6 is already an impressive smartphone, but there are always improvements to be made. The Galaxy S7 will likely get one of the best screens available on a smartphone, maybe even better than a 4K display, perhaps 8K. 

If Samsung wants to take advantage of their recent entry into the virtual reality sector, a better screen would definitely help out. The Samsung Gear VR is a headset that can be attached to Samsung smartphones, and if the Galaxy S7 wants to use the Gear VR, an ultra-sharp screen would help.

Fingerprint sensors have been found on most recent smartphones, but an even more secure unique identifier is out there. This could be the first time that Samsung is able to include an iris scanner. This would require at least one advanced front-facing camera. With an iris scanner, Galaxy S7 owners could point the phone at their eyes and unlock it.

The Samsung Galaxy S6 Edge used curved edges on its screen. The Galaxy S7 might have similar curved edges on both sides of the display. Both of these curved edges would display notifications.

An excellent audio experience could be coming very soon to the Galaxy S7. It is expected to have bass-heavy speakers on both the top and bottom of the device. 

Samsung will want to find a way to improve the battery life of the latest Galaxy. This might require a larger battery, which could mean sacrificing some internal components for the battery.

A new rumor from South Korean website Newsis (in Korean) is reporting insider information that states the Galaxy S7 is way ahead of schedule, up to three months ahead of its usual cycle. This could mean Samsung wants to push this device along quickly so that they can start testing it and then release it.

Even being ahead of schedule, it is unlikely that Samsung will release another Galaxy S device in 2015, but early 2016 could happen.
