Instagram app opens calculator?

[Ash]

When I click on the app for Instagram it opens my phones calculator instead. (I have an android). Does anyone know how to fix this?

Android sucks. I have one. Get an apple phone, or if you can't, restart the phone by holding the on/off button. Or, delete the app and download it again.

delete the icon for instagram (click hold and drag it to the recycle bin looking thing) and then drag the icon from your apps drawer back into the home screen

Go to playstore and uninstall and then re-install Instagram from the playstore, ie either search for Instagram or directly go to "my apps" and do the steps suggested by me. Then restart your phone.

This should solve your problem. Most probably, it seems as some virus issue or misplacement of the icons. Still check if performing the above steps helps.
