Instagram also provides a data saver option to help users limit their data usage with the app. As we’ve already mentioned that limited signal can also be a cause for blurry Instagram stories, you can try turning it off too.
Just open your profile tab or your profile picture and click on the three horizontal lines on the top right corner of your screen. This will open the menu options.
Here, tap on Settings which looks like a gear icon.
Then, select the Account settings.
Now, tap on the Cellular data use option.
You can see all the cellular data usage options provided by Instagram in this section.
Here, all you have to do is make sure that the Data Saver option is turned off. This will ensure a more stable internet connection when you upload on Instagram.
Now, try to upload the story and see if the quality has improved.
