If youve picked up a new Galaxy S25, Galaxy S25 Plus, or Galaxy S25 Ultra, you might miss some of the most useful new features. Here are some tips and tricks to help you get the most out of your new device.1. Turn on Galaxy AIThere are numerous AI tools to try.

Before you get going, you need to turn all of this on, and register for a Samsung account at the same time (if you havent already), which is free to do.Open Settings, then tap Galaxy AI and Continue, and sign up for a Samsung Account (or sign into an existing one). You then get full access to the Galaxy AI apps, including Interpreter (for live translations) and Browsing assist (for website summaries).2. Configure the Edge PanelSamsung phones come with an Edge Panel of shortcuts you can access at any time by swiping across the thin bar on the right of the display. This feature lets you create persistent shortcuts to commonly used apps and untilities. It can make your typical navigation process much quicker. To change the available shortcuts, or change the Edge Panel position, tap Display then Edge Panels from Settings.3. Adjust advanced camera settingsYou can dig deeper into the camera settings.

For more options, including ISO speed and white balance, swipe across the camera modes under the shutter button, then tap More and Pro.4. Choose your assistantBy default, Galaxy S25 phones use Google Gemini as the digital AI assistant that pops up when you press and hold the power button. To change this to Samsungs own Bixby, open Settings and pick Advanced features > Side button > Long press to make the switch.5. Customize the lock screenYou get plenty of control over lock screen widgets.

From Settings, tap Lock screen and AOD to change the clock position, for example, and set how the always-on display (AOD) works when your phone is locked.More settings live in the Wallpaper and style section of Settings. Not only can you customize the lock screen wallpaper from here, you can always tap on the editable areas to change which widgets and which shortcuts are available from the lock screen.6. Transform your drawings with AIGalaxy AI can produce great pictures even if your art skills leave a lot to be desired. Open the Edge Panel from the side of the screen, then tap Drawing Assist: Draw out an image on screen with your finger or the S Pen, then tap Generate to have AI bring it properly to life. The results are somewhat inconsistent, but you can try repeatedly until you get something that fits your needs. 7. Create ambient wallpaperAmbient photos are one of your wallpaper options.

Create a secure folderYou cant necessarily be sure no one else will ever have access to your phone, but you can lock away the most sensitive apps and files behind another lock screen. Think of it like another layer of security. From Settings, open the Security and privacy menu, and tap More security settings > Secure Folder.9.
