[Update: Galaxy A40s too] Samsung Galaxy A40 gets Android 11 based One UI 3.1 update

Are you using a Galaxy phone? You are lucky as Samsung is releasing the latest Android 11 updates and there’s no stopping. After releasing the stable Android 11 update to a series of Galaxy phones, the update is now available for Galaxy A40. For the past couple of weeks Samsung is rolling out the latest Android 11 update with One UI 3.1 and Galaxy A40 will also get the same One UI 3.1 update.

This article was originally published on March 22nd.

Galaxy A40 is among some popular budget phones from 2019 and it was released with Android 9 Pie out of the box. Later the phone received Android 10 based One UI 2.0 update. And so, this will be the third major update for the device which will allow users to experience the latest features on their Galaxy A40.

The Android 11 based One UI 3.1 update is available for Galaxy A40 with firmware version A405FxxxU3CUC2 for model number SM-A405FN. And looking at recent Android 11 updates from Samsung this update will most likely bring the latest March 2021 security patch on Galaxy A40.

The latest Android 11 update comes with a bunch of new features along with bug fixes and performance improvements. If you have Galaxy A40 then you will be receiving Android 11 and One UI 3.1 features with this update. As of now, we don’t have the complete changelog, but we are guessing it will have similar features as Galaxy A50 Android 11 update. Some of these features include chat bubbles, improved notification controls, support for Google home controls, enhanced privacy settings, camera improvements, and more.

Galaxy A40 Android 11 update is currently available in Germany and Russia. But we know Samsung that they don’t delay updates so we can expect the update to be available in the remaining regions soon.

If the Android 11 update is available in your region, then you can expect the update over the air. But in case if you did not receive the notification, then you can manually check for the update by going to Settings > Software Update. You will see the latest update, where you need to click on Download & Install button to get the update.

But in case you didn’t get the update on your phone even when it is available for your regions. Well, in that case, you can always choose the manual upgrade option with Firmware. You can download Galaxy A40 Firmware from Samsung Firmware Downloader, Frija tool, SamFirm tool, or SamMobile website. If you are using one of the tools then enter your model and country code and download the firmware. Once downloaded, you can flash the firmware using the Odin Tool. I recommend you take a backup prior to diving into the process. That’s it.

May 14th – One UI 3.1 now available for Galaxy A40s

Samsung now starts pushing the Android 11 based One UI 3.1 update for the Galaxy A40s. The update hits the Galaxy A40s in China with A3050ZCU4CUE1 build number. The latest build comes with April 2021 monthly security patch along with a bunch of new features.

Visual Design

Motion is smoother and more natural than ever, with improved animations and haptic feedback for common interactions. And the interface responds to different screen sizes to provide the best experience on any device, whether it’s a phone, foldable, or tablet.

Accessibility for everyone

One UI Core 3 recommends useful accessibility features for you based on your usage. The improved Accessibility shortcut makes accessibility features easier to start and use. You can use the Speak keyboard input aloud feature to get voice feedback of your typing even when TalkBack is turned off.

Stronger privacy protection

You can now let an app access to your microphone, camera, or location just one time. Any permissions that an app hasn’t used in a while will be automatically revoked. You can no longer give apps permission to always see your location in the regular permission popup. To let apps access your location when they’re not in use, you need to go to the location permission page for the app in Settings.
