S10 vs S10E

There are a few differences:

-S10e has a flat screen, not a edged one
-S10e does not have a telephoto camera on the rear camera like the other models
-S10e has a capacitive fingerprint sensor on the side, the s10 has a ultrasonic fingerprint sensor on the screen
-S10e has a 3100mAh battery, the S10 has a 3400mAh battery

This site actually has the specs side by side if you want to compare yourself as all I've done it hifghlight the biggest differences (smaller ones include ram, but 8gb is an option in both models)
