In normal order, the latest mobile from Samsung is the best!
Have had S2, S3, S4, S6, S8 and S9 before but this is my first "plus" variant.
Both the S8 and the S9 were very good, but the S10 + is better at just about everything.
The processor is a little faster, the frame memory larger and faster, the battery much larger and so on.
Functionally, they are very similar, except for the Live and Night camera modes that have been added.
The screen is as sharp as the S9an. However, the design has changed slightly due to the camera being recessed into the screen, and the fingerprint sensor built into the screen.
The only minus I have is that the fingerprint sensor only works in 50% of the cases with my screen protector.
Might be worth mentioning that the camera is only at 12 megapixels. So Samsung is far far ahead of its competitors, but it's probably the best 12-megapixel camera on the market. Great pictures if you only see them on the phone. Not as impressed when you see them on a 4K-IPS PC screen.
