What to do for smooth gameplay

@kavybhanushali we really do not deal with this on here. We really do more of hardware repairs etc instead of gaming optimization. You may need to check the forums that deal with mobile gaming.

Just for general information, it will depend on what the requirements are for the games that you want to play. As for your hardware, the more memory your phone has the better it is to play. Memory on your phone can't be upgraded. You can't add memory but you can always use an additional microSDXC card. The rest will really depend on your phone's settings.Start by checking what Samsung Suggest for the game playing settings.
