The growing conversation around the missing app icons on Android issue has caught our attention. While it seems confusing, it’s a problem that some Android users have encountered.

After all, the presence of app icons on our Android device’s home screen is important for convenient access to our frequently used applications. When your OnePlus Ace 2V’s icons suddenly disappear, it can leave you feeling lost about how to use and access your apps.

No worries, though. We’ve got you covered with a simple guide in this article. Just follow the steps, and you’ll get those missing app icons back on your OnePlus Ace 2V.

Part 1: Make Sure if the Missing App Is Installed

Before proceeding with troubleshooting the missing app icon on your Android device, it’s essential to confirm whether the app is still installed or if it has been accidentally deleted. To do it, you can have a quick check on Google Play:

  • Step 1: Go to the Play Store.
  • Step 2: Tap your Google profile at the top right and find Manage apps and devices.
  • Step 3: Open Manage and select the “Installed” tab.

Check if the missing app is installed

Now, see whether you can find the app icon that disappeared on your Android. If you can’t find it, it means the app has been accidentally deleted, and you can install it back on your device. However, if it’s confirmed to be installed on your Android but remains missing from your home screen, you can continue the following practice.

Part 2: How To Find the Missing App Icon on Android

If you’ve confirmed that the missing app is installed, but its icon is nowhere to be found on your home screen, don’t fret—there are several solutions you can take to locate and restore the missing app icon on Android.

1. Check hidden apps

How could the Android phone icon be missing? Well, app icons can disappear from your home screen for different reasons. One of the common reasons is you might have accidentally hidden it in your phone. To find and check whether the app is hidden, the steps can be different depending on the phone model you are using.

However, as a general guide, you can follow these steps:

  • Step 1. Go to your phone’s Settings.

If your app icon disappeared on your Android, you can also easily restore it by adding the app to the home screen from the app drawer. Follow the step-by-step guide below:

  • Step 1. Open the App Drawer on your Android. To do this, swipe from the bottom to the top, starting from your home screen. The App Drawer is where all your installed apps are neatly listed.
  • Step 2. Once you open the App drawer, locate the app icon that has disappeared from your home screen. For example, you lost the phone icon on Android. Then, look for the phone icon from the App Drawer.

App icons can also disappear on the Android home screen if you unintentionally or intentionally disable them. Certain phone models even offer a functionality known as ‘Freezer,’ allowing users to temporarily halt the apps.

To re-enable the disabled app, you can follow the steps here:

  • Step 1. Open the Apps & Notifications on the Settings.
  • Step 2. Select the app which icon is missing on your home screen. For example, tap the phone app if the phone icon disappears on your Android.
  • Step 3: In the App Info, tap Enable.

4. Reset Android to factory settings

If the previous methods don’t work, you might need to do a factory reset on your OnePlus Ace 2V. But before doing that, it’s important to back up your data first because a factory reset will clear all your data and cache when you press the reset button.

How to reset Android to factory setting:

  • Step 1: Go to your Android Settings.
  • Step 2: Select Backup and Reset > Factory data reset. Then, choose to erase all data.

Please be mindful that performing a factory reset on Android will reset your Android completely to its initial state.
