Update Galaxy S20 (all models) to One UI 2.5 Official Firmware

From this post, you will be able to update your Samsung Galaxy S20 to OneUI 2.5 Android 10 official firmware. Not many expectations over many things in terms of updates on the Android market, but a few years ago, Samsung started trying to change its bad image with its new version of OneUI.

This fork of its operating system released its version 2.5 to the Note 20 series, and there was no clarity of when it would drop for the S20 series. But by surprise, it has already begun to arrive.
Obviously, it hasn’t happened around the world, but users in Europe already reported receiving the update, which includes several new features, the ability to use DeX desktop mode wirelessly, and simply share WiFi credentials.

The company announced it through their Blog, bringing to the S20, S20+, and S20 Ultra a new, improved version of Single Shot, as well as new capabilities in the video recording, ability to choose the microphones.

The device capable of recording in 8K can now record at 24 frames per second, giving a more cinematic touch.

It’s definitely fantastic news that Samsung tries to change the Android ecosystem that takes a longer time to receive the latest updates.

We’ll see how they’ll do it when it’s time to release on to multiple non-flagship devices, from different ranges beyond the premium to OneUI 3, based on Android 11.

The new version 2.5 of the Samsung’ User Interface has been official since the beginning of August 2020, whose release came alongside the Galaxy Note 20. Today, the company has already started rolling OneUI 2.5 updates to a number of devices in its catalog, highlighting Galaxy S20 Series mobiles, but many other devices are also on the update list.

Features of OneUI 2.5

Although the company itself did not give prior knowledge about any update date, the update with all the new features of the new version of OneUI is rolling right now. In that sense, the features of OneUI 2.5 that we have seen on Galaxy Note 20 will now also be available in other high range phones of the manufacturer, starting with the iconic Galaxy S20 series.

For example, in Europe, the update is coming with the builds G981BXXU4BTH5 (Galaxy S20 5G), G986BXXU4BTH5 (S20+ 5G), and G988BXXU4BTH5 (S20 Ultra 5G); although 4G variants should also be receiving the software in the next few days. In addition, these updates have been detected in countries such as Holland, Hungary, Italy, Germany, and Portugal; so Spain will soon get it.

What’s new in OneUI 2.5

However, we cannot be so happy; So, although the list of mobiles available to receive the new software is a bit long, not all features of OneUI 2.5 will reach your systems. So the update will not be the same in all cases, as the functions will vary according to the device.

Still, here’s what’s new in this new version of OneUI based on Android 10; and that in theory, they should get most of the devices:

Camera

  • Pro video mode with the ability to control the microphone. It can be linked with the Galaxy Buds to use as a “professional style lavalier microphone.”
  • 8K video recording 24fps.
  • 21:9 aspect ratio video recording

Samsung Notes

  • Audio bookmarks in Samsung Notes. This allows you to synchronize your notes with audio recordings from conferences or meetings.
  • Import and write to PDF files.
  • Auto-save and sync between your phone, tablet, and PC.
  • New background and template color options.
  • Add handwritten text to typed documents.

Samsung DeX

  • You can now connect to your smart TV wirelessly if it supports duplication of your phone screen.
  • You can use multi-finger gestures on your phone to control DeX on your TV or monitor. Swipe up 3 fingers to see recent apps, down to return to the home screen, or left or right to switch between apps.

Connectivity

  • Easily share the password of the WiFi network connected to nearby Galaxy devices in your contact list.
  • View WiFi connection speeds in your environment before connecting to them.

Samsung Reminders

  • You can pre-set the time and location information for upcoming meetings and tasks.
