On some game if u played with a modded game/app and u reinstall an updated app/game it should save ur progress, but if it wont best advice is go to ur android folder OBB/data rename that game folder to something or add an extra letter to end, install the new updated mod game/app, dont open it yet ,go back to obb/data folder delete that letter or rename to ur original name and ur done play ur game, but then again on moded games/apps if u do require to restart from zero you should be able to get to that progress in minutes maybe 1 hour but then again its worth it, up to u, but liek i said it should save ur progress, if ur device is rooted u can just install the new updated app/game over the old instalation
