Have you noticed in the list of applications or in the “For Developers” menu a strange item with the name com.android.dreams.basic and don’t know what it is responsible for? This system component is built into the Android operating system and is responsible for the functionality known as Daydream. When your smartphone is connected to a charger or docked, the screen can switch to a special mode that shows a clock, photos, news or animations.
For most users who use their phone normally without a dock, this feature seems useless and even harmful, since it can consume battery power in the background. Understanding what this is com.android.dreams.basicwill help you decide whether to leave this service active or whether it is better to deactivate it to save device resources.
In this article we will analyze in detail the purpose of this package, its impact on performance and security, and also provide step-by-step guide for managing it through system settings. You will learn why it may appear in the list of active processes and how to correctly disable it without disrupting the operation of other system services.
Purpose and functionality of the system service
The component com.android.dreams.basic is part of the Android framework, which is responsible for the visual design of the screen during periods of inactivity of the device. Called "Daydream" by Google, the feature was originally envisioned as a way to turn a smartphone or tablet into a dashboard when connected to a power source. Instead of just showing a black screen or lock screen, the device can display useful information.
In its basic implementation, this service provides minimalistic screens such as colored shapes, a clock, or a photo slideshow. However, on modern smartphones from Samsung, Xiaomi and other manufacturers, this functionality is often expanded or replaced with their own solutions (for example, Always On Display), but the system core com.android.dreams.basic often remains in the firmware for compatibility.
It is important to understand that this is not a virus or malware. This is legitimate system processsigned with a digital certificate from Google or the device manufacturer. Removing it or forcing it to stop will not lead to a system crash, but may make it impossible to set screensavers in the device menu.
⚠️ Attention: On some custom firmware, disabling this component may affect the operation of the “Sleep Mode” function or specific energy saving modes that use the same libraries for output images.
If you have never used the Screen Saver feature and your phone is not docked, it is safer to disable this service to prevent background activity.
Impact on battery and performance
One of the main questions that worries users: does it drain battery? com.android.dreams.basic battery? The process itself in sleep mode consumes negligible resources. The problem only occurs if the screen saver feature is activated and set to start when charging is connected or in standby mode.
If the screen lights up and starts playing an animation or slide show while the phone is in your pocket or bag (due to false alarms from sensors or settings), this leads to significant energy consumption. In such cases battery consumption can increase by 5-10% overnight, which is critical for mobile devices.
In addition, the constant operation of the graphical screensaver interface creates a load on the processor and RAM. On older or budget smartphone models with a small amount of RAM, this can cause micro-slowdown of the system immediately after exiting screensaver mode.
- 🔋 An active screensaver prevents the screen from going into deep sleep by keeping the backlight or OLED pixels on.
- 📉 Background process activity is minimal if the function is disabled in the settings display.
- ⚡ On devices with AMOLED screens, screensavers with bright colors can accelerate the wear of the matrix.
Where to find the settings and how to manage the process
To check the work status com.android.dreams.basic and change its parameters, you will need to go to system settings. The path to this menu may differ depending on the version of Android and the manufacturer's shell (MIUI, OneUI, ColorOS), but the logic remains the same.
Usually the required section is located in the menu Settings → Display → Screensaver. In some versions of Android this item is hidden deeper: Settings → System → For developers → Launch screensaver. If you cannot find this item, the manufacturer may have hidden it or replaced it with its own solution.
Inside the menu you will see a list of available screensavers. This is where the process is active com.android.dreams.basic. You can choose what exactly will be displayed: colors, clocks, photos, or third-party applications that support this mode. Disabling the Screensaver switch completely stops the service.
⚠️ Attention: The settings interface may change with Android security updates. If you do not find the “Screen saver” item, check the “Screen and brightness” section or use the search in settings.

Security and virus scanning
Often, users start to panic when they see an unfamiliar package name in the task manager or in the list of application permissions. The question arises: is it not com.android.dreams.basic a disguise for a miner or a Trojan? In the vast majority of cases, this is a false alarm.
A real system process has certain characteristics that distinguish it from a fake. Firstly, it is located in the system memory section, where regular applications cannot access without root access. Secondly, it does not ask for suspicious permissions, such as access to contacts, microphone or SMS.
However, attackers may try to disguise malware under system names. To ensure security, check the application details in the menu Settings → Applications → Show system processes. Find “Screensavers” or “Basic Daydreams” in the list and look at the application size and installation date.
| Option | Normal value | Suspicious value |
|---|---|---|
| Application size | Less than 5 MB | More than 50 MB |
| Date of installation | Date of phone purchase | Recent date |
| Permissions | Display on top of other windows | Access to SMS, calls |
| Location | System partition (/system) | User memory (/data) |
If you find inconsistencies, for example, the process requires access to geolocation or was installed yesterday along with some game, it is recommended to scan your device with an antivirus. Real com.android.dreams.basic never requests access to the user's personal data.
What to do if a process is using 100% CPU?
If you see in the battery monitoring that com.android.dreams.basic is consuming a lot of power, even when the screensaver is turned off, this may indicate a software glitch (bug). Try clearing the Screensavers app cache in the Apps settings menu. If this does not help, the only way out is to disable the application through ADB or the developer menu.
Instructions for completely disabling the service
If you decide that you do not need the screensaver function and want to be sure to stop the process com.android.dreams.basic, simply turning off the switch in the settings may not be enough to completely remove it from memory. For a radical solution, you can use disabling it through the developer menu or ADB.
The easiest way is to use the standard application menu. Go to Settings → Applications, click on the three dots in the corner and select “Show system processes”. Find “Screensavers” (or Basic Daydreams) in the list, click on it and select the button “Disable”. This will prevent the service from starting even after a reboot.
For more advanced users who want to completely remove the package (only with root access or via ADB without root), there is a disable command. Connect your phone to your computer, enable USB debugging and enter the command in the terminal:
adb shell pm disable-user --user 0 com.android.dreams.basicThis command “freezes” the application for the current user. It will disappear from the list of installed apps and will stop consuming resources. To get everything back, use the command with the parameter enable instead disable-user.
⚠️ Attention: Disabling system components via ADB requires caution. Make sure you enter the package name correctly, otherwise you may disable critical interface services.
Disabling through the app menu is the safest method, reversible at any time without connecting to a computer.
Possible problems and ways to solve them
Sometimes users are faced with a situation where, after updating Android, the screensaver starts to turn on by itself, ignoring the settings. This may be due to a conflict in energy saving profiles or a bug in the firmware of a specific manufacturer.
In such cases, it is recommended to reset accessibility and screensaver settings. Go to Settings → System → Reset settings → Reset accessibility settings (path may vary). This will return the settings com.android.dreams.basic to factory values, which often eliminates software glitches.
Also, the problem may manifest itself as a “flickering” screen or a black screen when trying to exit the screensaver. If this happens regularly, it is better to completely remove updates for the Screensavers application in the application management menu in order to roll back to the stable factory version.
- 🔄 Resetting accessibility settings often solves the problem of spontaneous activation.
- 🗑️ Removing application updates returns the stable factory version of the service.
- 🛡️ Checking third-party launchers: some shells may take over control of the screensaver.
Before resetting accessibility settings, write down your current settings for large text or invert colors if you are using them for the visually impaired, as these will also reset.
Frequently asked questions (FAQ)
Is it possible to remove com.android.dreams.basic without root access?
It is impossible to completely remove a system application without root access, since it is located in a protected section of the system. However, you can “disable” it through the app settings or using the ADB command, which essentially stops it from working and hiding it from the interface.
Why does the com.android.dreams.basic process run in the background?
It runs in the background to monitor the state of the device (whether it is connected to charging, whether it is in the docking station). This is necessary to instantly launch the screensaver when the conditions are met. If the screensaver function is disabled, its activity should be minimal.
Does disabling this service affect the operation of Always On Display?
No, these are different technologies. Always On Display is controlled by display drivers and individual manufacturer system services. Disabling com.android.dreams.basic should not affect the clock when the screen is off.
I deleted this process and the phone stopped charging. Is this connected?
No, there is no direct connection between the screensavers and the power controller. This is most likely a coincidence or a problem with the cable/connector. However, in rare cases, on specific firmware, a conflict in system services could cause a crash. Try rebooting your device.
Is it safe to use ADB commands to disable?
Yes, the disable-user command is safe and reversible. It does not physically delete files from the system, but only marks the application as inactive for your user. You can always turn it back on with the same command with a different flag.
