Why not Samsung provide updates for older devices and everytime it's ignored and forget. You can see in screenshots and this type of answer given before when i was complaied in November-january month . But till date I'm not received any updates.
bro you ignor3d AF.. Every company ignore older one.. because they need to focus on new one.. which are on trends & about update.. MI use never get updates if you're new or old... you're not receive any update.
if you need update then i suggest Pixel phones or 1+8
