This post will allow you to download and install OneUI 2.1 on Samsung Galaxy A51, which is based on Android 10. The device is now one year old. Despite being released before the Galaxy S20, it has many similarities in design elements with the most recent flagship. Galaxy A51 is one of the best selling Samsung phones in recent days. To improve user experience, the brand has released One UI 2.1 for this device. You can download it from the link given below. We also have a tutorial on installing it manually; read ahead!
Samsung Galaxy A51 comes with Android 10 out of the box. The Android version remains the same on this new firmware, but there are several tweaks and improvements from Samsung, including the One UI 2.1. Most of the features, like revised text sizes and icon placements, are derived from the Galaxy S20 series. Moreover, the camera modules are also getting new modes inspired by the Galaxy S20. As Android 11 is still under Google’s development phase, the system version is not updated yet on the Galaxy A51. But we hope Samsung will bring that soon for their devices once it gets released for the manufacturers.
Samsung Galaxy A51 One UI 2.1 Update
Based on Android 10, this new firmware brought many UI tweaks on-board and updated the One UI (Samsung’s proprietary skin) from 2.0 to 2.1. Being a decimal bump, One UI 2.1 has tons of refreshments over the previous build.
Here are some of the key highlights of what’s new on One UI 2.1:
1. One UI 2.1: This latest UI carries various changes such as better icon placements, font size refinements, and other tweaks to improve the overall design. New notification pull-down button to improve accessibility as well.
2. Quick Share and Music Share: Quick Share is similar to AirDrop, which will let you send files to other compatible devices. On the other hand, music share lets you play music on Bluetooth devices.
3. Live Caption Mode: This is an exciting feature in One UI. Live Caption Mode gives you subtitle of whatever your device is playing, translates podcasts and other content into subtitles for easier referencing.
4. AR Emoji Update: AR emoji is to have some fun with your photos and videos. It got refined with the new build in One UI 2.1. It’s a feature that hasn’t been much discussed, but it still serves its purpose.
