As far as I know the main differences from s10+ to s10e are
-5 cameras (instead of 3);
-8 GB RAM (instead of 6);
-4100 mAh battery (instead of 3100 mAh);
-Edge display (instead of flat);
-Resolution 3040x1440 Wide Quad HD+ (instead of 2280x1080 Full HD+);
-Gorilla Glass 6 (instead of Gorilla Glass 5);
-Ultrasonic Fingerprint Scanner that is embedded into the screen (instead of Electrostatic Fingerprint Scanner on the Power button).
