Google Gmail has a wonderful feature of syncing your Android device with your Google account. But, for one reason or another, it refuses to sync. Now you’re left wondering why.

Oftentimes it’s as simple as reactivating your sync settings or updating your phone and the Gmail app itself. Other times it’s a minor issue like data corruption–an easy fix, for sure.

Are you Online?

Syncing your Android to Google Gmail requires a constant network connection; that’s how it transfers your information. Without it, syncing ceases to function until a network connection is available.

1. Open your Quick Settings Menu. Pull the taskbar down to reveal it.

2. Wi-Fi should be glowing if it’s turned ON. If it’s greyed out, tap it.

Important: If your data is turned on and your Wi-Fi is activated, it can cause a network connection conflict. Disable one or the other to avoid this problem.

Are You Logged Into Google Gmail?

A simple mistake that needs a simple fix. Double-check that you’re actually signed into Google Gmail. It can’t sync when an account isn’t logged it or linked. This prevents anyone from syncing data from a Google account for simply knowing the email address. Here’s how:

1. Open the Google Gmail app.

2. Log in, if you aren’t already. If you weren’t, you’ll be asked to log in with your account information or provide a password.

If You Aren’t In a Plane, Turn Off Airplane Mode

What is Airplane Mode?

When it isn’t causing panic, Airplane Mode is a helpful feature when you’re on a plane. Hence, “airplane mode.” Its purpose is to block off any signals your device is currently emitting as to not interfere with a plane’s own tools and communication.

Turning It Off

This sneaky little feature is always getting flak. Considering it’s often seen hugging the Wi-Fi option, you forget it’s there and wind up tapping it by accident. And now, it’s blocking Google Gmail’s syncing function. Here’s how you turn it off:

1. Open your Quick Settings Menu. Pull the taskbar down to reveal it.

2. Find the icon of a plane. It will say “Airplane Mode” if it’s labeled. When it’s lit up, it’s turned ON. When it’s greyed out, it’s turned OFF. You want it off.

Restart your Android Device

Technology needs a good reboot every now and then. Imagine running a marathon. Now, imagine running a marathon every day, all hours of the day, with no breaks. A smartphone, computer or tablet, experience a similar problem. Give your Android a break.

Don’t restart your Android device. Shut it down completely. Give it 60 seconds and boot it back up.

1. Hold the Power button.

2. When prompted, choose Shutdown or Power Off. It varies from manufacturer to manufacturer.

Keeping your Device Up-to-date

Update Google Gmail

Updates make the world go around. Apps, computers, phones, tablets–everything within the sphere of technology–are in a constant state of improvement. For computer-based technology, it comes in the form of updates. While the hardware may have been massed produced by machines, the code was written by developers, and errors were bound to find their way in.

Errors come in the form of corrupted data, or security holes, or glitches and bugs. With a simple update, it can write the mistake that was made.

On the other hand, updates for high profile apps are absolutely necessary considering they need to work with the servers. An outdated app is a security risk. Change that by doing this:

1. Open the Google Play Store app.

2. Open the menu. It’s the three horizontal lines located in the top-left corner of the screen.

3. Select My Apps & Games.

4. Under the Updates tab, select UPDATE on the Google Gmail app if there’s one available.

Update your Android Device

Following the same line of thinking as the previous section, “Update your Google Gmail App,” updating your Android device is just as important. Ignore enough updates for either phone or apps, and eventually they’ll no longer work together. Fix that by doing this:

1. Open the Settings app. It’s the GEAR icon.

2. Keep scrolling until you located System Update. Select it. Alternatively, depending on your phone, System Update can also be found in About Phone. Results may vary.

3. Update each individual component.

Give Google Gmail’s Permissions

When you use an app to, for example, edit a photo, you’ve given that app access, or rather “permission,” to your gallery. In this case, Google Gmail needs permission to more than just your gallery.

Without permissions, certain apps won’t function correctly. For example, a GPS app is useless if it doesn’t have access to your location. You need to give Google Gmail permission if you’d like to sync your Android device. And here’s how:

1. Open the Settings app. It’s the GEAR icon.

2. Head over to Apps. Select it.

3. Locate Google Gmail among your list of currently installed apps. Tap it.

4. In “App Info,” select Permissions.

5. Tap the slider, next to Storage, to the right to turn it ON. It will turn blue. While you’re at it, if you’d Google Gmail to sync other data, now is the time to do so.

Double-check your Sync Settings

Clear your Android’s Storage

Google Gmail won’t sync if your storage is nearing full. You’ll need to delete any unneeded media: pictures, videos, and apps. If you’re interested, rather than delete pictures you want, pull them from your phone onto a computer and save them or upload them to Google Drive via computer.

Clear Google Gmail’s Cache

It’s possible some data was corrupted at some point. Simply clearing the cache will do it some good.

1. Open the Settings app.

2. Locate Apps.

3. From the list, select the Google Gmail app.

4. Head into Storage.

5. Tap Clear Cache.
