Google will soon block Android versions lower than Honeycomb (3.0) effective September 27, 2021. The main reason for the change is security as Google is no longer providing security updates for Android up to Gingerbread. This might be harsh but looking at Android’s history, you’ll note that Android 2.3.7 was released about 10 years ago.
“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 says. “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 cannot be upgraded further than Android 2.3.7 after the September 27th deadline, you’ll still be able to use some Google services via the browser.
