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 Oppo A18’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 Oppo A18.

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.

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

“All my apps disappeared from my home Android screen. What should I do?”

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.
• Step 2. Use the search bar to look for “Hidden app.”
• Step 3. Once you find the “Hidden app” settings, watch the list to see if the missing app is there. If it is, you can toggle off the switch to unhide it.

2. Move the app to the home screen from the App Drawer

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.
• Step 3. Long-press the Icon of the missing app and move it to the desired location on your home screen. You can drag it to an empty space or a specific folder.
• Step 4. Release to drop the app icon onto the home screen.

3. Re-enable disabled app

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. While in a frozen state, the app remains inactive and doesn’t appear on the home screen until you unfrozen it.

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.

How to reset Android to factory setting:

• Step 1: Go to your Android Settings.

2.2 Restart Android and turn on Bluetooth again

One of the most common solutions in technology is simply to turn it on and off again, which is the case to happen here. By restarting your device, you can clear out any problems you may be suffering from to help it get up and running again. Here’s how;

1. Turn your Oppo A18 off by holding down the Power button

By clearing the cache, you can restart the service and hopefully clear up any issues or problems you may be experiencing.

1. On your phone, navigate Settings > Application Manager, and you’ll see all the apps and services on your phone. Locate and select the Bluetooth service.
2. Select the Storage option
3. Tap the Clear Cache option
4. Go back of the Menu and restart your phone
5. Now turn your Bluetooth feature on and turn connecting it to your preferred device

2.4 Remove paired devices

Sometimes, you may have a problem with the Oppo A18 device you’re trying to connect to via Bluetooth, especially if this is a device you’ve updated. To counter and repair this, you’re going to need to remove the paired devices saved with your device and then reconnect them.

Here’s how;

1. From the Main Menu of your Oppo A18, head to Settings > Bluetooth > Connected Devices.
2. Turn Bluetooth on, and you’ll see all the connections your Oppo A18 is paired with
3. Go through these settings and remove/delete/forget every connection on your device
4. Now when you go to connect to a device using Bluetooth, repair the Oppo A18 device, enter the passcode, and use a fresh paired connection.

2.5 Use Bluetooth in safe mode

If you’re having problems with your connection and paired devices, sometimes you may have conflicting software faults in your device that are causing the problems. If this is the case, you’ll need to boot your Oppo A18 in Safe Mode.

This is an operating state in which your phone will run the bare minimum services it needs to perform. If your Bluetooth works in Safe Mode, you know you have an app or a service that’s causing the problem.

Here’s how to find out;

1. Hold the power button down, so the Android power menu turns on
2. Long-press the power button again and the restart in Safe Mode option will come up
3. The phone will automatically boot into Safe Mode
4. Wait a minute on the Main Menu
5. Now turn on your Bluetooth and connect it to your preferred device

2.6 Turn on the discoverable feature

To ensure your Bluetooth can connect to other devices, it’s important to make sure you’re making your device discoverable to other Bluetooth devices. If it’s hidden, other devices won’t be able to find it, and sometimes it can bug and prevent connections.

Here’s how to turn on your Bluetooth discoverable feature;

1. From the home screen of your Android, navigate to the Menu> Settings > Bluetooth
2. Toggle the Bluetooth switch, so it’s on
3. Under the available settings, tick the box that allows your Bluetooth device to be discoverable
4. Turn your Bluetooth feature on and connect to the Oppo A18 device you’re trying to connect too

Sometimes, you might not even have a problem with your Oppo A18, but rather the Bluetooth device you’re trying to connect to, whether that’s a Bluetooth speaker, an in-car entertainment system, or any other kind of Bluetooth device.

By testing out another Bluetooth device to see if it will work with your preferred device, you can rule this out from being the issue.

1. Disconnect your Oppo A18 from the Bluetooth device and turn your Bluetooth off
2. Now take another Bluetooth device and connect this to the Oppo A18 device you’re trying to connect too. This could be another Android device, or even a computer or iOS device
3. If the new device doesn’t connect to your Bluetooth device, you’ll know there’s a problem with your Bluetooth device, not your Oppo A18
4. If the Oppo A18 devices connect, you’ll know there’s a problem with your Oppo A18

2.8 Place both devices within close proximity

One of the common misconceptions of Bluetooth is just how far the wireless range is of the service. You need to make sure your devices are well and truly close to each other to make sure a stable connection can be formed.

The further away the Oppo A18 devices are from each other, the less likely the connection will remain secure. As a rule of thumb, Bluetooth can work up to 100 meters, but to play it safe, always try and keep your devices under 50m apart.

2.9 Avoid interference of other Bluetooth sources

The final consideration you’ll want to think about is that Bluetooth radio waves, or wireless waves, can interfere with each other. This means they can bounce off each other or get muddled up and make things confusing from your devices.

With this in mind, you’ll want to make sure you’re limiting the amount of Bluetooth activity in the area where you’re trying to use a device. While uncommon, this could be the problem.

To fix this issue, turn off all the Bluetooth connections in the area. This includes computers, laptops, mobile phones, tablets, and any other Bluetooth devices you may have. Then, try connecting your Oppo A18 to the Oppo A18 device you were trying to use. If it works, you know you were experiencing Bluetooth interference.
