Instagram automatically saves your post once you upload a picture on the app. Since in iOS, memory is limited, you may not appreciate the idea of automatic save of Instagram photos. Hence a potential solution is to turn off the feature by tweaking the setting. Check out the tutorial to know how to disable automatic photo saving.
1. Open Instagram and go to your Profile.
2. Now click on the Gear icon to open Settings.
3. Now scroll down and find out “Save original Photos”. By default this feature is turned on which means whenever you post any picture on Instagram, it will be saved in your Photos app. So move the slider from right to left to turn it off.
4. It’s done. Now if you want to enable the feature again, move the slider from left to right.
