What Does Optimizing Apps Mean 1

Did you update your Android phone, and now it says, “Android is Starting… Optimizing Apps”? Have you observed this notification when you reboot your Android device while clueless about its meaning? Well, we have figured it out for you.

Quick Answer

When your device says “Android is Optimizing,” the operating system prepares an optimized version of pre-installed apps to be compatible with the updated software. This notification appears when an Android device reboots after a firmware or software update.

For once, you may think the word “optimizing” is good since it upgrades apps. Well, it’s not suitable when you’re stuck on the same screen every time you reboot your phone.

This article will elaborate on optimizing app notifications and how you can tackle this problem by following three effective methods. We will also state three main reasons this notification appears on your device screen every time.

Reasons for Optimizing Apps Notification

Are you wondering why you see an optimizing apps message every time you reboot your Android device? Here are the three main reasons for this issue.

Reason #1: Android Software Update

If you have recently updated your Android, the device is optimizing applications to make them suitable for the newer version

Optimizing after an update is to make the apps run faster with the new software version. And sometimes, it might optimize apps by asking to update them individually.

Reason #2: Incompatible App

Installing an application on your device is supposed to be compatible with the operating system. 

But after updating the software, some applications may constantly crash, having compatibility issues. Therefore, Android optimizes the old applications to make them compatible with the new software system.

Reason #3: Developer Mode

Installing third-party applications on your Android device may require running it in “Developer Mode”. The notification saying “Android is Starting… Optimizing Apps” may appear on every reboot if the developer mode is enabled on your device. Because the software checks for new changes in custom apps.

Fixing App Optimization

Don’t know what optimizing apps mean, and are you irritated by this notification appearing on your phone’s screen? Here are three easy methods to prevent your device from app optimization.

Method #1: Uninstall Apps

App optimization takes up to 10-15 minutes on every reboot, and it might take even longer depending on the number of apps on your phone. If any applications are crashing after the Android update, try uninstalling them with this easy process.

  1. Go to the “Home” screen and find the app that is not working correctly after the update.
  2. Keep holding the app icon until you see a pop-up menu that says “Uninstall”.
  3. Tap on the “Uninstall” option and then tap “Confirm” to remove that app permanently.
  4. You can also hold and drag the app icon until the “Uninstall” option appears on the screen.
  5. Keep holding the icon while dragging it to the “Uninstall” option on the screen.
  6. Finally, see if you see the app optimization message on the next boot.

Method #2: Factory Reset Device

This method may seem extreme, but it can help bring your device and its operating system is the most compatible position. You can “Factory Reset” your Android device by following these steps.

  1. Go to “Settings” > “System” > “Reset Options”. Here you’ll find different reset methods.
  2. Tap on “Factory Reset” to erase all data to bring your phone to its default state.
  3. Finally, tap “Confirm”, and your device will reboot after a few minutes without an app optimization notification halting your screen.

Before performing Factory Reset, remember that all the data, including apps, contacts, photos, and logs, will be deleted. So, back up your device before going for Factory Reset.

Method #3: Boot in Safe Mode

The safe mode can assist your device with compatibility mode, which can help you investigate problems with incompatible apps. You can safely boot your Android device with this step-by-step process.

  1. Hold the “Power” button on your Android device until the “Power Menu” option appears.
  2. Hold the “Power Off” option until the “Reboot to Safe Mode” pop-up appears.
  3. Tap on “OK”, and your device will reboot in safe mode within seconds.
  4. If you don’t see optimizing messages in safe mode, uninstall the apps one by one to find the one causing the issue.
