The new sensor uses an RWB filter to give better results for low light photography.
Some new 1.0 micron pixels being pushed in also means Samsung has been able to reduce the size of the sensor. It may mean the camera on the Galaxy S7 won't protrude as much as it does on the Galaxy S6.
A 20MP camera sensor has been spotted in the testing process as well, so far it's not certain what it'll be on the Galaxy S7.
The Galaxy S7 is currently rumoured to be launching at the start of February. Failing that, we might end up seeing the new phone at the end of the February instead.
