There are cases where the previous version of an Android app was performing better, and after an upgrade you would like to downgrade it.
Unfortunately, the Play Store does not allow you to downgrade an Android app directly, so if you have not kept the apk file of the previous version, you are forced to stay in the latest version.
Also some applications are automatically updated without leaving you the margin of choice on the subject. But even without having to have access on rooting your phone you can always run an older version of an app. Below you will find a guide that shows you the best method to do downgrade one application.
Οι εφαρμογές στο OS Android είναι συνήθως ένα και μοναδικό συμπιεσμένο αρχείο με κατάληξη APK. Για κάθε έκδοση της κάθε εφαρμογής υπάρχει και ένα διαφορετικό αρχείο. Τα αρχεία των παλαιοτέρων εκδόσεων δεν τα προσφέρουν δυστυχώς οι κατασκευαστές τους με αποτέλεσμα να είστε αναγκασμένοι να τα αναζητήσετε σε χώρους τρίτων προσώπων. Όμως θα πρέπει να είστε πολύ προσεκτικοί κατά τη λήψη αρχείων από το διαδίκτυο, δεδομένου ότι μπορεί μερικές φορές να έχουν ενσωματωμένα malware. However unfortunately this is the only way to get your hands on the older versions for free.
The site APK Mirror is a free repository of old versions and has a reputation for being safe as the site was created by Android Police (but never be sure of anyone). The website claims to provide "clean" files, especially for application degradation.
Its operation is relatively simple. You can search for the application you are looking for and then choose the version you are interested in through a range of publications.
Once you've found the right file, download the APK file on your phone. Uninstall the original app from your device (the latest version you no longer care about). Open File Manager on your phone and navigate to the space where you have the APK file (usually in downloads).
Tap on it to open it and it will install on your device. You may need to allow installation of apps from unknown sources. This is done from the Settings > Security > Unknown sources menu. Of course, make sure you have turned off automatic information of applications
Finally keep in mind that older versions of apps are more prone to hacking and support, so be sure to keep your personal data to someone backup. Also make sure to scan the APK file and the entire phone with an antivirus application after installation.
