I have a Samsung Galaxy M21 smartphone (4gb variant) which has been facing an issue for quite a long time.
Whenever I launch Instagram app in my phone and click a photo from the camera in the app, after a while the app starts to lag. Once I exit from the app and try to relaunch Instagram, it doesn't open smoothly anymore! When I go back to the recent screen option and try to open Instagram app from there, it lags and doesn't open quickly!
Eventually after sometime this lagging problem in the Instagram app stops and the app again starts smoothly without any lag!
I have been trying to fix this issue for a long time and have tried several ways to solve this thing, but nevertheless the problem still persists.
Recently I had got an Android 11 update, and hoped that this problem might have been resolved but it still hasn't been fixed!
I don't know whether it's a software issue or the app is not properly optimized! If anyone of you have been facing this same kind of a problem and know how to fix this issue, please kindly help me too!
PS: This lagging issue just occurs with the Instagram app and not with any other third party or in built apps. Other phone with lower specs and older Android versions still are able to run the Instagram smoothly, but in this case I have no clue what's the root cause of this whole thing.
