Samsung tablet users have reported issues with their devices going into sleep mode while in use. This issue has been observed in the Samsung Galaxy S6 Lite and the Samsung Tab A, which has a default screen timeout of 30 minutes. Several factors could be causing this problem, such as the use of a Samsung cover with a magnet/sleep feature, S-pen usage with AirView enabled, or specific software settings. To prevent the tablet from automatically going into sleep mode, users can adjust the 'Screen timeout' in Settings > Display, enable ''Stay awake' in Developer Options, or use apps that keep the screen on during charging.

What You'll Learn
The Samsung Tab A has a limited screen timeout by default
The maximum screen timeout setting for the Samsung Tab A is 30 minutes, and this cannot be extended beyond that timeframe. However, there are a few workarounds to keep the tablet active for longer. One way is to enable the "Stay awake" option in the Developer Options. To do this, you need to first enable Developer Options by going to Settings > About tablet > Software information and tapping on the Build number several times until you see a message that says "Developer mode has been enabled". Once Developer Options are enabled, you can find the "Stay awake" setting and toggle it on. This will keep the screen on while the tablet is charging.
Additionally, you can adjust the "Screen timeout" setting in Settings > Display to extend the timeout duration up to the maximum of 30 minutes. Regular software updates can also help optimise power management and prevent premature sleep activation.
Another option is to use third-party apps that are designed to keep the screen awake. Apps like Tasker (paid) or Automate (free) offer automation features to keep the screen active.
If the issue of unexpected sleep mode activation persists, it may be a glitch, and you might need to reset your device or contact Samsung support for further assistance.

The tablet case might be causing the issue
If your Samsung tablet is going to sleep while in use, the tablet case might be causing the issue. Some Samsung tablet cases have a magnet/sleep feature that can trigger the device to go into sleep mode when the cover is open and flat against the back of the tablet. This occurs when pressure is applied to the edge of the screen with the Samsung cover folded back.
If you are using a cover with a magnet/sleep feature, try removing the cover and see if the tablet still goes to sleep. If the tablet stays on, then the cover is likely the issue. You can try adjusting the position of the cover or using a different cover that does not have a magnet/sleep feature.
Additionally, some Samsung tablets have a "Stay awake" option in the Developer Options that can be enabled to keep the screen on while the tablet is charging. To access this option, go to Settings > About tablet > Software information and tap on the Build number repeatedly until "Developer mode has been enabled". Then, return to the main Settings menu and look for "Stay awake" under Developer Options. Toggle this on to keep the screen awake while charging.
Another possible solution is to use an automation app like Tasker or Automate to prevent the tablet from sleeping. These apps can be customised to keep the screen awake while the tablet is in use. Additionally, regularly updating your device software can help optimise power management and prevent premature sleep activation.

S-pen usage could be a factor
The S-pen is a standout feature of Samsung flagships and has been for many years. It is bundled with Samsung tablets, although not all models support the S-pen. The S-pen has various features, including Air Actions, which allow the S-pen to function as a remote control. It can be used to play and pause music and media, advance PowerPoint slides, and control other apps and features. The S-pen can also be used for note-taking, editing photos and videos, and annotating existing content. It can translate words or phrases by hovering over them and can magnify anything on the screen up to 300%.
The S-pen can be set up to unlock the device without a PIN or password. It can also be set up to warn the user if they walk away from their device without the S-pen. Additionally, the S-pen can be used to create notes while the screen is off by removing the S-pen and writing on the screen.
However, S-pen usage may cause the Samsung Tab A to go into sleep mode while in use. This issue has been reported by users who were using LectureNotes with Samsung's AirView enabled. Disabling this service resolved the issue. Therefore, S-pen usage, particularly with certain apps and settings, could be a factor in the Samsung Tab A sleeping while in use.
To address this issue, users can try disabling Samsung's AirView or other S-pen features that may interfere with the tablet's sleep mode. It is also recommended to test run the tablet in safe mode to determine if the issue is related to the S-pen or other factors. If the problem persists, resetting the device or seeking further technical support may be necessary.

Try adjusting the 'Stay awake' setting
If your Samsung Tab A keeps sleeping while in use, there are a few things you can try to adjust the 'Stay awake' setting and prevent this from happening.
Firstly, check if you are using a cover with a magnet or sleep feature. Some covers have a magnet that can cause the device to go into sleep mode when the cover is flipped open and placed flat against the back of the tablet. Try changing your cover or removing the magnet to see if this solves the issue.
Secondly, if you are using an S-pen with Samsung's AirView enabled, this could be causing the problem. Try disabling AirView or using a different stylus to see if this prevents the tablet from sleeping while in use.
Additionally, you can try adjusting the screen timeout settings to prevent the tablet from sleeping too quickly. Go to Settings > Display > Screen timeout, and set the timeout period to a longer duration or the maximum available.
If these solutions do not work, you may need to test run your tablet in safe mode to determine if the issue is caused by a glitch or a faulty app. If the problem persists in safe mode, it may be a hardware issue that requires servicing. Otherwise, resetting your device may resolve the problem.
By following these steps and adjusting the 'Stay awake' setting, you should be able to prevent your Samsung Tab A from sleeping while in use.

Use an app to prevent sleep mode
There are several reasons why your Samsung Tab A might be sleeping while in use. One possible cause is the use of a Samsung cover with a magnet/sleep feature. If you put pressure on the edge of the screen with the cover folded back, the tablet may interpret this as an attempt to activate sleep mode and respond accordingly. Another potential issue could be related to S-pen usage, particularly if Samsung's AirView is enabled.
To prevent sleep mode and keep your tablet awake, you can try the following methods:
Utilize the Settings Menu:
- Navigate to Settings > Display > Sleep and set the screen timeout to "never". This will keep your tablet from sleeping while it is in use.
- Alternatively, enable Settings > Developer Options > Stay Awake. This option may be located under Settings > About > Build Number, or it might be in another location such as Kernel Version.
Use an App:
- You can use automation apps like Tasker (paid) or Automate (free) to prevent your tablet from sleeping. These apps allow you to create flows or routines that keep your device awake.
- Another option is the Caffeine app, which is free, lightweight, and highly effective in preventing devices from sleeping.
Manage Sleeping Apps:
- Samsung devices have a feature called Sleeping Apps that puts unused apps to sleep to save battery life. However, this can interfere with apps you want to keep running in the background. Go to Settings > Battery and Device Care > Battery > Background Usage Limits and ensure that the “Put unused apps to sleep” option is disabled.
- Additionally, Samsung has an “Auto-disable unused apps” feature that will put apps back to sleep after a few days, even if you manually wake them up. To prevent this, go to Apps > Samsung App Settings > Game Booster and ensure that "Auto-disable unused apps" is turned off.
By following these suggestions, you can prevent your Samsung Tab A from sleeping while in use and maintain the functionality of your device.
