If you want to disable the auto sleep/wake function on your Android tablet, there are a few methods you can try. One way is to go into your tablet's settings and select Display or General, where you may be able to set the screen timeout to never. You can also try using an automation app like Tasker or Automate to prevent your tablet from sleeping. If the issue is caused by a magnetic tablet cover triggering the sleep function, you might need to return the cover or try rooting your tablet and using a framework like Xposed to disable the smart cover sensor.

What You'll Learn
Use an automation app
If you want to prevent your Android tablet from automatically going to sleep, you can use an automation app like Tasker (paid) or Automate (free). These apps allow you to create custom profiles and tasks to control your device's behaviour, including preventing it from sleeping.
Another option is to use an app like Timeriffic or Llama - Location Profiles, which are free solutions available on the Play Store. These apps might offer the capability to keep your device awake.
Additionally, depending on your tablet model, you may have the option to set the screen timeout to "never" under Settings > Display > Sleep. This will prevent your tablet from automatically sleeping.
If your tablet supports power management settings, you can also try going to Settings > Power and adjusting the sleep and wake-up times. Here, you can enable Scheduled Wake Up and Scheduled Wake, specifying the times for your device to sleep and wake up. However, if you have a screen lock enabled, it may interfere with the wake function, so it's best to turn it off in Android Settings > Security.

Adjust screen timeout settings
Adjusting the screen timeout settings on your Android tablet can enhance your user experience and optimise battery life. It can also be helpful when troubleshooting.
To adjust your screen timeout settings, first, open the Settings app on your device. From there, scroll down to Display. In the Display settings menu, look for the Screen Timeout settings option. Tap on it and choose the timeout duration that suits your needs. The default is usually 30 seconds or one minute, but you can adjust it to 15 seconds, two minutes, five minutes, 10 minutes, or even 30 minutes. Some devices may also include a "None" or "Never" option, which completely disables the timeout so that the screen stays on until you manually turn it off.
If your device doesn't have the option to disable screen timeout in the settings app, there is no guaranteed method to force the display to stay on. However, you can use Android Debug Bridge (ADB) to set the timeout to a very long duration or a custom duration not offered in the settings menu.
Please note that having no screen timeout enabled can drain your battery quickly if you forget to turn off your device. Additionally, certain apps, like video players or games, might prevent the screen from timing out.

Check for a strong magnet in the cover
If you are experiencing issues with your Android tablet's auto sleep/wake function, it is possible that there is a strong magnet in the cover. This is a common issue with some tablet covers, where the magnet used to activate the sleep function when closing the cover is too strong and triggers the function when the cover is folded back.
To check if this is the case, carefully open your tablet cover and inspect the inside for any visible magnets. Magnets are usually located near the edges of the cover, especially in the left or right corners when holding the tablet in landscape mode. If you locate a magnet, it is likely that it is the source of the issue.
One simple solution to this problem is to use a metal plate. Place a spare metal plate, such as a thin piece of aluminium or steel, between the tablet and the cover in the bottom left or right corner. This will block the magnetic field from reaching the tablet's sensor and prevent the auto sleep/wake function from being activated.
Alternatively, you can try disabling the auto sleep/wake function in your tablet's settings. This can usually be found under "Display" or "Connected Devices," but the exact path may vary depending on your tablet model and operating system. For example, on a Samsung Galaxy Tab, you can go to "Settings" > "Display" > "Lock screen" > "Ambient display" and toggle off "Use Ambient Display."
If you cannot find the option to disable the function in your settings, you may need to consider returning the cover and opting for one that is specifically designed for your tablet model, such as those made by Samsung, which are less likely to have this issue.

Try a different tablet cover
If your tablet has an auto sleep/wake function, it likely relies on a magnet embedded in the cover. This magnet activates a sensor in the tablet, which triggers the sleep/wake function when you open or close the cover. However, not all tablet covers are created equal, and some may not have this magnet in the correct spot or at all.
If you're having trouble with your tablet's auto sleep/wake function, one possible solution is to try a different tablet cover. Look for a ""smart" cover designed specifically for your tablet model. These covers typically include the necessary magnet and can help ensure the auto sleep/wake function works properly.
For example, if you have a Samsung Galaxy Tab S3, some users have reported that the Samsung keyboard cover/case does not include the necessary magnet. In this case, you would need to use the power button to turn the tablet on and off. However, Samsung's regular (non-keyboard) cover for the Tab S3 does have the magnet and works perfectly with the auto sleep/wake function.
Similarly, if you have a Samsung Galaxy Tab 4 7.0, it may only have an Auto Wake setting and not Auto Sleep. In this case, you might need to enable the "Book Cover/Auto Wake" option in the settings and ensure that the screen lock is not set up, as it will nullify this feature.
It's worth checking with the manufacturer or seller of the tablet cover to confirm if it is designed to work with your tablet's auto sleep/wake function. If not, you may need to purchase a different cover or consider using an automation app like Tasker or Automate to prevent your tablet from sleeping. Alternatively, you can set the screen timeout to "never" in your tablet's settings.

Return the cover
If you're having issues with your tablet case triggering the sleep/wake function, you may want to consider returning the cover and trying another one. This issue could be due to a design flaw in the cover, such as a magnet that's too strong, which may require you to root your tablet and use a third-party framework to disable the sensor.
To return the cover, you'll need to contact the retailer or manufacturer and follow their return process. Make sure to have your proof of purchase and original packaging ready. It's also a good idea to provide a valid reason for the return, explaining the issue you're facing.
Before returning the cover, ensure that your tablet's settings are not causing the issue. Check your screen timeout settings and ensure that you don't have a screen lock set up, as this can interfere with the auto-wake function. You can usually find these settings under "Display" or "Device Manager" in your tablet's settings.
Additionally, some tablets have a “General” settings tab where you can enable the Automatic Unlock feature. This feature allows the cover to unlock the screen when opened, but it doesn't always enable auto-sleep. Refer to your tablet's user manual or support forums for specific instructions on enabling this feature.
If you still encounter problems after checking your settings and trying a different cover, you may need to explore other solutions, such as using automation apps to control the sleep/wake function or contacting customer support for further assistance.
