According to a report by Appsflyer, Android users are much more likely to uninstall applications from their smartphones than iOS users. To be more precise, Android users are about twice as likely to uninstall an app from their phone, as compared to an Apple iPhone user. The conclusion was drawn by the analysts after going through data based on 500 apps and about 20 million devices. The comparatively short-lived interest in multiple apps, as exhibited by the Android populace could be a result of any one or multiple of the following reasons.
Android users outnumber iPhone users quite significantly, and unless the data was collected by keeping that fact in mind, the sheer numerical superiority can definitely contribute to such an overwhelming difference in behaviour between the two groups.
The Play Store now officially has more apps than the App Store, but when it comes to quality, the App Store is still leading. The Play Store has a lot of buggy and broken apps on it, which might be the reason why Android users uninstall a lot of the apps just shortly after downloading and using it.
Finally, it could be the absolute low-end, outdated garbage which some of the sellers (including Samsung) still sells to their customer base in developing nations like India, Pakistan, etc. Some of these horrible outdated phones even have internal storage capacities as low as 4GB (Useable memory being anything in between 1.2GB to 2.2GB at most). Add to this the fact that these devices also sport ancient hardware that can't even start the modern games properly and you have an instant answer for a lot of those quick uninstalls.
