the lcd touch screen brightness cannot adjustment factory

Adaptive Brightness uses the sensors in your Android phone to detect changes in ambient light and adjust the brightness of your screen accordingly. However, sometimes, the auto-brightness stops working, forcing you to make manual brightness changes.

In this article, we take a look at a few troubleshooting steps to help you diagnose the problem and restore auto-brightness on Android to its working state.

Every phone is different, but you can often enable or disable Adaptive Brightness from the Notifications panel. To do this on a Samsung phone, swipe down the notification panel and tap on the See more tab (down arrow icon). Then, toggle the switch to enable Adaptive Brightness.

Adaptive Brightness keeps track of your manual brightness adjustments and applies them automatically in similar lighting conditions. However, issues with your brightness preference data can cause the auto-brightness to malfunction.

An easy solution here is to reset Adaptive Brightness to its factory default settings. You can do this using Google’s Device Health Service app that comes pre-installed on most Android phones.

Tap on the Reset adaptive brightness settings button and then confirm the action. This will reset your auto-brightness settings to their factory default.

Once the reset is complete, you may see your display dim a little or more depending on your current brightness level. Now Adaptive Brightness should start working as normal and learn from your inputs on the go.

If it is a prevalent issue, your smartphone manufacturer may release an update to fix the bug. Check if a new update is available for the device and install it to see if it helps fix the problem.

Your phone will scan for available updates and prompt you to install any if available. Your phone will restart after the update is installed. After restart, check if the auto-brightness feature is working again.

While you wait for a bug fix, consider using a third-party auto-brightness app such as Velis Auto Brightness. It replaces your phone’s default auto-brightness function and allows you to customize the brightness graph to fit your need.

Furthermore, Velis Auto Brightness allows you to create multiple user profiles, add apps to the exception list, and choose between different sensors such as the brightness sensor or proximity sensor to measure light levels.

A malfunctioning sensor can cause the auto-brightness feature to stop working. You can perform a routine test for the light sensor to detect hardware issues.

Now, move your palm closer to the light sensor. If the value decreases as your move closer to the light sensor, then your light sensor is working correctly.

Adaptive Brightness in Android can stop working for several reasons. To troubleshoot the problem, reset Adaptive Brightness settings in the Device Health Service app. If not, perform a routine sensor test to detect hardware issues.

When you update the Bios version to 1.5.0 on your Dell XPS 15 7590 system, you may not be able to adjust the LCD brightness. Open the Device Manager, you would find that multiple entries under the Monitors(See Figure.1). At that time, you can not increase or decrease the brightness in the following ways:

Try to adjust the brightness from the Display Settings/Windows Mobility Center(See Figure.2). The value can adjust but the display is stuck at a certain brightness, there is no effect if you adjust it to 0 or 100.

To test everything with your screen i suggest you launch the test menu and see if everything works there, there is a special button called "dimming" there to test as such;

I tried all the troubleshooting that Advance 23 stated except this - "You can also change the screen brightness by going into the *Setup* tab on the front panel of the printer and then into *Preferences* and choosing *Screen Brightness*." The problem with this is that I cannot access my front panel of the printer because my screen is blank!!

I attempted to access the firmware to which you referred - when the screen asked me to choose my printer, it stated under status "unavailable". My printer is on, and I can print to it, so the printer is not unavailable to my system. I presume that this means the firmware is not meant for my printer.

This is rather frustrating, and I appreciate your help. But it appears that this problem is prevalent and might need more than just a "reboot" of my printer.

When you need to use your notebook frequently for business, you need to be comfortable to be productive. The Lenovo ThinkPad features a brightness control function that enables you to make the screen dimmer or brighter. For example, looking at a bright screen in the dark will strain your eyes, but dimming the screen increases your viewing comfort. Dimming the screen also helps save battery power, so you can use the laptop longer before you need to charge it.

Select the Networkicon on the right side of the taskbar, and then move the Brightnessslider to adjust the brightness. (If the slider isn"t there, see the Notes section below.)

Some PCs can let Windows automatically adjust screen brightness based on the current lighting conditions. To find out if your PC supports this, select  Settings >System>Display. Select Brightness, look for theChange brightness automatically when lighting changes check box, and then select it to use this feature. This automatic setting helps make sure your screen is readable wherever you go. Even if you use it, you can still move theBrightness slider to fine-tune the brightness level for a built-in display.

You might also see another check box displayed: Help improve battery by optimizing the content shown and brightness. Some Windows PCs can automatically adjust the screen brightness and contrast based on content that’s displayed on your built-in screen. For more info, see Adaptive brightness and contrast in Windows.

You might not see the Brightness slider on desktop PCs that have an external monitor. To change the brightness on an external monitor, use the buttons on it.

If you don"t have a desktop PC and the slider doesn"t appear or work, try updating the display driver. Select Search on the taskbar, type Device Manager, and then select Device Manager from the list of results. In Device Manager, select Display adapters, then select the display adapter. Press and hold (or right-click) the display adapter name, then select Update driver and follow the instructions.

Laptops are designed to be portable, which means that they have different components and programming than a standard desktop PC. That portability makes them great business tools, but laptop displays are more difficult to troubleshoot than a desktop monitor, since the presence of a battery and of power-saving modes in Windows mean there are more possible reasons for a screen to go dim.

Adjust Brightness Settings Most laptops have brightness controls on the keyboard, and it’s possible that bumping one of these keys has dimmed the screen. Look on your keyboard for a sun icon; if the icon is in blue or gray, you need to use the “Function” key to access it. Tap the key to adjust the brightness. If the screen dims further, tap the key beside it to raise the brightness.

Power Saving Mode Your laptop has different power profiles to prolong battery life once you disconnect the computer from AC power. A basic power-saving plan will, by default, immediately dim the laptop’s screen in order to save power when your computer is running on battery. Your screen going dim could be as simple as that -- the power cord connecting the laptop to the wall isn’t connected properly, and the computer is running on battery. Sometimes, a computer can get stuck in its power-saving mode, which would mean that your screen would remain dim after you wake the computer up; reboot your computer to reset power saving mode.

Changing Power Saving Modes You don’t need to leave the power-saving mode configured to dim the screen while running on battery. Click in the top right corner of your screen and type “Power,” then click “Settings” and “Power and battery” to open the power-saving profiles. Most battery mode profiles are called “Power saver” -- click this profile to edit its settings and then click “Change plan settings.” Change the value on “Dim the display” to “Never,” then click “Okay.”

Hardware Issues Occasionally, a laptop screen’s hardware can fail. If your screen is getting increasingly dim as time goes on, the liquid crystal display may need a new backlight or need to be replaced entirely. You can check by connecting an external monitor to your computer and seeing if the display is also dim on the monitor. If it is, a software setting is dimming your display; if the external monitor is bright and clear, the laptop’s screen is likely damaged. In instances of hardware issues, it’s best that you check your computer’s warranty and return it to the store from which you purchased it for service.

If the display is flickering: Make sure your Mac and display are connected to one another with good quality cables and adapters. You may also be experiencing interference from a nearby power line, a fluorescent light, a radio, a microwave oven, another computer, or another electrical device. Try relocating nearby electrical devices, or moving your Mac and display.

If you see bright or dark spots on a flat-panel or Mac laptop screen: Your display may have pixel anomalies. If you suspect your Apple display contains a high number of anomalies, contact Apple or an Apple Authorized Service Provider for service. Repairs performed by untrained individuals or using non-genuine Apple parts may affect the safety and functionality of the device.

If none of these solutions work: If you have an Apple display and can’t correct the problem, contact Apple or an Apple Authorized Service Provider for service. Repairs performed by untrained individuals or using non-genuine Apple parts may affect the safety and functionality of the device.

Slowly drag your finger to the bottom right corner without lifting. Try to move your finger slowly enough that you can count to 10 before reaching the opposite corner of the screen.

Under your Pixel 5 phone’s screen, at the top center, you can see a white dot. This white dot is your proximity sensor. When your proximity sensor is on, the dot shows through the display. The dot can blink or stay solid.

Your proximity sensor keeps your phone’s screen off while you hold your phone near your face during a call, when your screen is locked, and when used by certain apps. Keeping the screen off helps save battery and avoid accidental taps on the screen.

All Pixel phones have proximity sensors. Because the Pixel 5’s display goes almost to the edge, you can see the Pixel 5’s sensor under the screen. Check our Pixel 5 phone diagram.

IMPORTANT: A factory data reset will remove all data from your phone. While any data stored in your Google Account will be restored, all apps and their associated data will be uninstalled. Before you perform a factory data reset, we recommend backing up your phone.
