Your Samsung Galaxy S10 was made to change the brightness of the display, depending on ambient lighting conditions, using a feature named Adaptive Brightness. In Power Saving mode, how bright the screen is can be affected by the battery level of the device.

How Can I Turn Off Adaptive Brightness On My Galaxy S10 If I Don’t Like The Feature?

- Launch the Settings application.
- Click “Display.”
- Disable Adaptive Brightness by scrolling its button to the left.

More Information About Your Samsung Galaxy S10
Samsung Galaxy S10 is a line of Android-based smartphones manufactured, released and marketed by Samsung Electronics. The Galaxy S10 series is a celebratory series of the 10th anniversary of the Samsung Galaxy S flagship line, its top line of phones next to the Note models. Unveiled during the “Samsung Galaxy Unpacked 2019” press event held on 20 February 2019, the devices started shipping in certain regions such as Australia and the United States on 6 March 2019, then worldwide on 8 March 2019. It is the tenth generation of Samsung’s Galaxy S series of smartphones.
As has been done since the Galaxy S6, Samsung unveiled flagship Galaxy S10 and Galaxy S10+ models, differentiated primarily by screen size and an additional front-facing camera on the S10+. In addition, Samsung also unveiled a smaller model known as the Galaxy S10e, as well as a larger, 5G-compatible version, the Galaxy S10 5G.
The Galaxy S10e, S10 and S10+ launch prices started at $749, $899 and $999, while the S10 5G’s launch price is $1299.
The S10 line comprises four models with various hardware specifications; the main S10 and S10+ respectively feature 6.1 and 6.4-inch 1440p “Dynamic AMOLED” displays with HDR10+ support and “dynamic tone mapping” technology. Or the user could decide to switch the display resolution to 720p or 1080p. The displays have curved sides that slope over the horizontal edges of the device. Unlike previous Samsung phones, their front-facing cameras occupy a rounded cut-out near the top-right of the display, and both models utilize an ultrasonic in-screen fingerprint reader. While providing better performance over the optical in-screen fingerprint readers introduced by other recent phones, they are not compatible with all screen protectors (due to this, the S10 and S10+ are both supplied with a pre-installed plastic screen protector).
The S10 range ships with Android 9.0 “Pie”. They are the first Samsung smartphones to ship with a major revamp of Samsung’s Android user experience known as One UI. A main design element of One UI is intentional repositioning of key user interface elements in stock apps to improve usability on large screens. Many apps include large headers that push the beginning of content towards the center of the display, while navigation controls and other prompts are often displayed near the bottom of the display instead.
The fingerprint scanner has a security flaw that allows anyone to unlock the phone (this also affects the Note10). Samsung is aware of the issue and working on a fix. Samsung issued a patch on October 23 which is intended to resolve the issue. Initially, the update will only be available in South Korea, but will soon be available for other regions.
