The Samsung Galaxy S7 isn't due until next April, but already the rumour mill has started churning. SamMobile has some early details on the project, including what's being tested.
According to the site, the phone is codenamed Project Lucky within Samsung. Apparently that's a reference to the fact that the number seven is thought to be lucky.
SamMobile also has some possible specs for the handset, which it claims is being tested with the Samsung-made Exynos 8890 chipset.
However, a Qualcomm Snapdragon 820 is also thought to power some variants. Given Samsung's past form, that suggests that the model you can buy could depend on where you are in the world.
At the Galaxy S6 launch, Samsung said it was still open to using Qualcomm's chips as long as they were up to standard. The Snapdragon 810 was plagued by overheating issues.
The S7 could also feature support for microSD cards, a feature that was missing from the Galaxy S6 and S6 Edge.
This angered many fans who prioritise expandable storage over a more premium design.
Samsung is testing a 20-megapixel camera on the device too, it's claimed, and is trailing an "all lens cover". What that is is anyone's guess, but it sounds like it could add extra functionality to the camera.
It's early days yet, so all this could change before we see the S7 in the flesh. Roll on the spring.
