how did you updated your last 2.1 software? if you simply updated it by using mobile data or wifi then this types of issues will comes only...that firmware needed to be flashed by odin or smart switch or through authorized Samsung service center especially when any big os update or new ui interface comes. this is one and only proper and recommended method....i am using s9 and I flashed it from service center first day ...my device running like champ no issues ....use smart switch or odin every time if possible....Samsung provides non A/ B partition type of ota software hence mobile data or wifi brings software holes maximum times
