Our samsung on 7 prime & other galaxy phones no screen shot in built, ever time we had using power button & Volume buttons for sreen shot. That's why buttons are damaging in the phone. Please check & update our request.
i have using samsung J7 prime which is 99% similar to On7 prime. i had no issue over this nor my any samsung phone has power button problems after using screenshots. i take more than 50 screenshots per day
you can take screenshots simply with only swiping your plam on screen so many feature rich options give by Sam's which is not available in other brands. if you have need notification panel screenshots by default, then you can wait for it or choose another brand or use third party app whichever you like. thank you.
