Updating apps without the Play Store is possible on Android devices but requires a bit of setup and effort. Here are the steps you need to take:
Enabling External Sources: Your Android device has a feature called “Unknown Sources” that needs to be turned on for the method to work. This will allow apps from external sources (other than the Play Store) to be installed on your device. To turn it on, go to your device's settings and under the “Security” tab, check the box labeled “Unknown Sources”.
Download Updated Version of the App: You can search for the updated version of the app you want to install. While downloading, make sure that you trust the source of the download.
Install the Updated App: After you have downloaded the updated version of the app, locate it on your device and tap on it to install. The installation can take a few minutes depending on the size and type of the app.
With these steps you should be able to update your apps without the Play Store. It is not a recommended method as using the Play Store is more secure and reliable, but if you ever find yourself in a situation where you must get an updated version of an app without the Play Store, then following these steps should make your job easier.
