Disable ecoenergy , if it's activated your phone will have better performances because of disabling app sync and then use more battery. Disable it bro don't activate any of batterie savers.
A50 is the original, soo normally Samsung sell more A50's than A50s's. But the S version has better specs, not really better but still slightly better.I prefer A50, and i have an A50 with the best specs available for the phone.
