Samsung tablets have a sleep/wake function that is activated by a magnet embedded in the tablet case's interior. When the case is opened or closed, the tablet turns on or off. This function is available in the Samsung Galaxy Tab 4 8.0 and 10, the Tab S5e, the Tab S7 plus, the Tab A 10.1, and the Tab A 2019. However, some users have reported issues with the sleep/wake function, such as the tablet turning off when the case is folded back or the tablet not turning on or off at all. To troubleshoot this function, users can try adjusting the settings by going to General or Advanced Features, then Accessories, and enabling the Book Cover/Auto Wake or Automatic lock option.

What You'll Learn
Samsung tablet models with auto wake/sleep functions
The auto wake/sleep function is a feature in many tablet cases. This function is typically facilitated by a magnet embedded in the cover, which activates a sensor in the tablet. The magnet must be strong yet nearly invisible.
It is worth noting that some aftermarket covers for the Tab A 2019 claim to offer an auto wake/sleep function, but it seems that these cases do not work as intended. Additionally, the Samsung OEM official keyboard cover for the Galaxy Tab S3 has an "auto sleep/wake" function, but it works differently from the standard auto wake/sleep function; the tablet turns on/off when connected/disconnected from the pogo pins on the keyboard.
When purchasing a tablet case with an auto wake/sleep function, it is important to ensure that the case is specifically designed for your tablet model, as the feature may not work otherwise.

Samsung tablet models without auto wake/sleep functions
Many Samsung tablets have auto wake/sleep functions, which are usually enabled by a magnet in the cover. However, there are some models that do not support this feature. Here are some examples:
Samsung Galaxy Tab A 2019
The Samsung Galaxy Tab A 2019 is one such model that does not have the auto wake/sleep function. This is due to the absence of a proximity sensor, which is surprisingly included in older models like the Galaxy Tab A 2016. Users have tried multiple cases for this tablet, but none seem to enable the auto wake/sleep feature.
Samsung Galaxy Tab 4 7.0
Some users have reported that the Samsung Galaxy Tab 4 7.0 does not automatically wake or sleep their device when the cover is opened or closed. However, it is worth noting that the larger Tab 4 models (8.0 and 10) seem to have both auto wake and sleep functions.
Samsung Galaxy Tab S3
While there are some covers that do enable the auto wake/sleep function for the Samsung Galaxy Tab S3, there are also reports of certain covers, like the original keyboard cover, that do not have this functionality. It is possible that this is due to a bug in Samsung's software or the absence of a magnet in the cover.
Samsung Tablets Without Keyboard Covers
In general, it seems that Samsung tablets without keyboard covers are less likely to have the auto wake/sleep function. This is because the keyboard cover connects to the tablet via pogo pins, and the tablet turns on and off based on this connection.
It is important to note that in some cases, users may need to enable the auto wake/sleep feature in their tablet's settings or ensure that there is no screen lock set up, as this can interfere with the function. Additionally, the strength and placement of the magnet in the cover can also impact the functionality.

How to enable the auto wake/sleep function on Samsung tablets
To enable the auto wake/sleep function on Samsung tablets, you will need a compatible tablet case or cover. The auto wake/sleep function is typically activated by a magnet embedded in the interior of the tablet case. When opened and closed, the tablet should automatically turn on and off.
If you have a Samsung Galaxy Tab 4 7.0, your tablet case will likely only have an Auto Wake setting and not Auto Sleep. To enable this, go to "General" settings, then tap "Device Manager" on the left side of the screen. Tap "Accessories", then "Book Cover", and check the box to enable Automatic unlock. This will unlock the screen when you open the cover, but it will not put the device to sleep when you close it.
For the Samsung Galaxy Tab 4 8.0 and 10, you can follow the same steps as above, and your tablet will have both Auto Wake and Auto Sleep functions.
If you have a Samsung Galaxy Tab A 2019, your tablet does not have a proximity sensor, so it is unlikely that any tablet case will enable the auto wake/sleep function.
To check if your tablet case supports auto wake/sleep, go to your tablet settings and scroll down to "Advanced Features". Tap "Accessories", then enable "Automatic Lock". If this doesn't work, your case likely does not support auto wake/sleep.

Samsung tablet cases with auto wake/sleep functions
For example, the Samsung Galaxy Tab S3 has a Smart Cover that enables the auto wake/sleep function. Aftermarket covers for the Samsung SM-T820 model have also been found to support this function. Additionally, the larger Samsung Tab 4 models, such as the 8.0 and 10, offer both Auto Wake and Auto Sleep settings, providing a seamless experience for users.
To enable the auto wake/sleep function on a Samsung tablet, users can follow these general steps:
- Go into the tablet's settings.
- Locate the "General" settings or Advanced Features" section.
- Select "Device Manager" or "Accessories".
- Look for a Book Cover" or "Automatic Lock" option and enable it.
It is worth noting that not all Samsung tablets support the auto wake/sleep feature. For instance, the Samsung Galaxy Tab A 2019 model lacks a proximity sensor, which is necessary for this functionality. Similarly, the Wi-Fi-only version of the Samsung Galaxy Tab 4 7.0 has been reported to have only an Auto Wake setting without Auto Sleep.
When purchasing a tablet case with auto wake/sleep capabilities, it is essential to consider the strength of the magnet and its discreet placement. A strong magnet ensures reliable function, while a nearly invisible magnet maintains the aesthetic appeal of the case.

Samsung tablet cases without auto wake/sleep functions
Some Samsung tablet models, like the Tab A 2019, do not support the wake/sleep function due to the absence of a proximity sensor. Similarly, the WiFi-only version of the Samsung tablet also lacks a proximity sensor and, thus, the auto wake/sleep function.
For Samsung tablet users who want to disable the auto wake/sleep function, one possible solution is to root the tablet and use a framework like Xposed to disable the smart cover sensor. Alternatively, one can modify the hardware by cutting open the case, removing the magnets, and gluing the case back together.
It is worth noting that the auto wake/sleep feature is more commonly found in Apple iPad cases, and even some aftermarket cases for Samsung tablets may have this feature. However, for those specifically seeking a Samsung tablet case without the auto wake/sleep function, it may be necessary to explore cases designed for older Samsung tablet models or opt for a universal tablet case that does not include this feature.
