Those who can't upgrade may still use the device's web browser to access Google services.

Google will no longer allow sign-in on Android devices that run Android 2.3.7 or lower starting September 27.

If you sign into your device after September 27, you may get username or password errors when you try to use Google products and services like Gmail, YouTube, and Maps.

"If your device has the ability to update to a newer Android version (3.0+), we advise you to do so in order to maintain access to Google apps and services on that device," the company said in an update.

"As part of our ongoing efforts to keep our users safe, Google will no longer allow sign-in on Android devices that run Android 2.3.7 or lower starting September 27, 2021," the company added.

Android 2.3.7 was released nearly 10 years ago.

When support ends for sign-in with a Google account on Android 2.3.7 and below, the users will receive a username or password error if they try to sign in to their devices or to add an email or calendar account.

"You will be able to sign into your account with a newer Android version (3.0 or newer). If your device has the ability to update to a newer Android version (3.0+), we advise you to do so," Google advised.

If you cannot update your device to a newer Android version (3.0+), you can try to log into your Google account on your device's web browser.

You can still use some Google services when logged into Google on your device's web browser.
