software glitches present..possibly came during software update...it's because may you used mobile data or wifi..it's allaways better procedure to use smart switch or odin flash.....anyway do factory reset for now
then you have to flash your last firmware from authorized Samsung service center or odin tools ...it's not only for Google play service....it's software glitch and holes...if software glitch present then none of the tips or tricks will help except firmware flash.....Samsung introduced smart switch that people's can get highest performance of devices but people doing same mistakes repeatedly and facing different types of issues in device ..software install simply by mobile data or non stable wifi is never ever the proper procedure or recommended there will be chances to get software holes by this only....don't worry just visit service center and flash your last firmware from them..it's absolutely free within warranty period of devices otherwise it will take rupees 236 only
one advice. To avoid software glitch during online update md5sum of downloaded files can be verified. If md5sum matches, proceed for update. otherwise abort the update. So software glitch must be avoided.
