Android users need to uninstall these apps ASAP as they are a security risk

Google is creating a new notification to warn you when you might have a risky app on your phone.

When it comes to older apps that you don't use anymore, do you uninstall them from your phones or do you leave them installed on the off chance that they might come in handy one day? In some cases, the developers of these apps might have dropped support for them, and Google might have removed these titles from the Play Store. If you weren't informed about any of these actions, you could end up with these apps and their icons remaining on your device, creating a security risk.

Google will soon inform Android users when an app they installed has lost developer support


Google is reportedly working on a way to inform Android users when apps they have currently installed are being delisted or removed from the Play Store. Android Authority discovered some strings of code in version 51.4.19 of the Google Play Store app warn Android users that apps removed from the Play Store will no longer receive software updates.

Currently, Android users are only warned via Play Protect when a serious security threat forces Google to remove an app from the Play Store or to label it a "potentially harmful app." When an app is removed from the Android app storefront by a developer, no warning or notification is issued. 

Google Play Protect scans your apps every day and also scans your device when you install a new app via the Play Store or by sideloading it.

The hidden strings of code all have something in common


The only way you might find out whether an app you have installed has been delisted from the Play Store would be if you read about it in PhoneArena or tried to install it on a new phone. But as noted earlier in this article, this might be about to change.

The strings of code that were found in the latest version of the Play Store say:

  • webp was removed from Google Play and will no longer receive updates.
  • webp and %2$d other apps were removed from Google Play and will no longer receive updates.
  • webp and type="image/webp" were removed from Google Play and will no longer receive updates.

It seems pretty obvious that Google plans to inform Android users when apps installed on an Android user's phone have been removed from the Play Store. Based on the strings of code, it would seem that the main point of these alerts is to inform Android users that apps that they had downloaded on their phones have been delisted from the Play Store. These apps will no longer receive updates.

At that point, Android users can determine whether they want to keep the apps on their phones or uninstall them.

Abandoned apps, when they stay on your phone, can be a security risk


Abandoned apps that remain on your phone can be a major security risk. The Black Duck Cybersecurity Research Center has discovered three apps that contain multiple vulnerabilities. These apps had been installed over two million times.

The problem is that these apps, which turn Android devices into a remote mouse and keyboard, all contain critical remote code execution (RCE) vulnerabilities. This is a major issue because an attacker can steal data (including personal data), install malware, and more.

Even though these apps are abandoned by the developers, if they haven't been uninstalled from your phone, they are still unpatched and offer attackers a way to get into your devices and grab your personal information. If you're wondering how this fits with Google's new feature, it is quite simple.

Why Google created the new warning about abandoned apps


By sending a notification to Android users telling them that apps they still have installed on their phones no longer receive support, it might give them incentive to delete the apps. Remember, these apps can be used by bad actors to access personal information, including credentials used by device owners to access their financial apps.

You don't have to wait for Google to release this new feature. If you have apps still installed on your Android phone that have been pulled from the Play Store by Google, they can be a security risk. Uninstall them now.
