Google Pay is Google’s answer to reducing the reason to have cash on you all the time. This is an age of technology and now security has finally stepped up its game to allow the opportunity of using a virtual representation of money we own. That doesn’t mean it always wants to work.

You go into a store, take out your wallet and give the cashier money. Transaction over. With your phone, however, you’re introducing hardware and software that could go haywire at the worst possible moments.

You may receive an error saying, This may be because your device is rooted, has an unlocked bootloader or is running a custom ROM. As a result, Google can’t confirm that your device meets Google Pay’s security standards.

Luckily, it doesn’t happen often and even when it does, there’s plenty of solutions to try.

1. Reposition your Device

A minor inconsistency somewhere might be interrupting the signal between the NFC antenna and the terminal. You may have to fiddle with the position of your device. Silly, but worth mentioning. Technology doesn’t always work the way you want it to.

2. Test on a Separate Terminal

You don’t have to buy another item, you just have to use a different terminal. This will single out whether or not it’s from your end or the terminal’s end.

3. Recently Installed Apps

Think back to when the problem started. Did you recently install any new apps? If you recently installed a third-party app, they can cause software issues. Make a list of all the ones you installed. If there’s a third-party app you desperately want to keep, install one at a time until the problem is recreated. When it does, then you’ll know which app was the culprit. Here’s how:

  1. Open Settings.

2. Open Apps.

3. Scroll up and down and locate every recently installed app. Select each one.

4. Select Storage in the app’s settings.

5. Tap Clear Data and Clear Cache. You don’t want any app data left behind.

6. Go back by tapping the arrow at the top-left corner.

7. Select Force Stop.

8. Tap Uninstall.

4. Update your Device

You can count yourself unlucky if an update was available just as you were about use Google Pay. Depending on the update, it can make Google Pay unusable until your phone is up-to-date. All you need to do is update your device. Here’s how:

1. Open Settings.

2. Select About Device.

3. Afterwards, select System Updates.

4. Finally, tap Check for system updates near the top.

5. Is Google Pay your Default Payment App?

Google Pay isn’t the only payment app out there. There’s plenty out there, but what matters is which payment apps cashiers do accept. You might be using one the cashier doesn’t use. Since Google Pay is widely used, double-check the payment app you’re using is Google Pay. Here’s what you do.

1. Open Google Pay.

2. Tap Payment.

3. Choose your preferred payment method.

4. Select Default for in-store purchases.

6. Clear your Cache Data

1. Open Settings.

2. Select Apps.

3. Tap on Google Pay.

4. Select Storage.

5. Tap Clear Cache and tap Clear Data.

7. Allow Near Field Communication

NFC, or “Near Field Communication,” shares information between two devices. Without NFC enabled on your device, you can’t use Google Pay properly. Here’s what you do:

1. Open Settings.

2. Tap on More.

3. Select NFC, near the top. The slider to the right should be blue and shifted to the right.

8. You’re Using a Rooted Device

If you’ve been happily enjoying your rooted device, but all of a sudden Google Pay doesn’t want to play nice, then Google Pay was recently updated. Your rooted device is out of date.

Having a rooted device does have its perks, unfortunately, that means you’re often barred from using certain apps when an update is available for that particular app. You’ll have to wait for your rooted device to get an update of its own before you can use Google Pay again.

Alternatively, you can use SuperSU or Magisk, to name a few.

9. Factory Reset

Before considering a factory reset, it should be noted what this does to your phone. Factory reset completely wipes your phone. Pictures, videos, apps, updates, data–everything– gets completely deleted. Your phone is rolled back to its original state when you first brought it home from the store. First, backup your data. Here’s how you do it:

1. Open Settings.

2. Select Backup & Reset.

3. First, select Back up my data. The slider to the right should be blue and turned to the right.

4. Tap Backup account. This will prompt you to choose which account the data is backed to.

Now that your data has been backed up, your Gallery is next.

1. Open Google Photos.

2. Select the Cloud Icon near the top-right corner.

3. Turn on Back up & sync. Turn the slider to the right to turn on. It should be blue.

4. Confirm the sync when prompted.

When all of your photos and videos have been backed up, you can reset your device. You’re nearing the point of no return. If you didn’t backup your data, your device will be purged and you can’t retrieve it. You have been warned.

1. Open Settings.

2. Select Backup & Reset.

3. Tap Factory Data Reset.

4. Confirm by selecting Reset Phone. When the process is finished, your phone will restart and you can initiate your new setup.

After All That and It Still Doesn’t Work

Factory resets don’t fix hardware issues, unfortunately. If there was something wrong with the internals all this time, it’ll still be present even after a hard factory reset.

It looks like you’ll need your smartphone fixed.
