If your Samsung Tab A is not waking up from sleep mode, there are several things you can try. Firstly, check if your tablet case supports auto-wake; to do this, go to Settings, scroll down to Advanced Features, select Accessories, and enable Automatic Lock. If this doesn't work, you can try test-running your tablet in safe mode to see if the issue persists. If it does, your tablet may require servicing. If not, you can try resetting your device. You can also try adjusting the screen timeout settings to prevent your tablet from going to sleep mode too quickly. Additionally, Samsung's Lift to Wake feature allows you to turn on the display by simply lifting your device or removing it from your pocket. This feature can be enabled in the Settings menu under Advanced Features, Motions, and Gestures.

The 'Lift to wake' feature is not available on the 2019 Galaxy Tab A
The Lift to wake feature is a convenient way to activate your Galaxy phone's display without pressing any buttons. By simply lifting your device or removing it from your pocket, the display turns on. This feature can be especially useful if you have face recognition set up, allowing you to activate and unlock your phone in one swift motion.
However, it is important to note that the Lift to wake feature is not available on all Samsung devices, including the 2019 Galaxy Tab A. This particular model lacks a proximity sensor, which is necessary for the Lift to wake function. As a result, you will need to manually wake the device by pressing the power button or performing a specific action, such as swiping up from the lock screen.
While the 2019 Galaxy Tab A may not support Lift to wake, there are still ways to automate the process of waking and sleeping the device. For example, you can purchase a case or cover that supports automatic wake and sleep functions. These cases often have built-in magnets that trigger the device's sleep and wake modes when closed or opened. However, it is worth noting that not all cases are compatible, and you may need to try a few options to find one that works for your tablet.
Additionally, you can explore other features offered by Samsung to enhance your experience. For instance, the Double tap to wake feature allows you to wake your device by simply tapping the screen twice. While this feature is not the same as Lift to wake, it can still provide a convenient way to activate your device without having to press any buttons.
Although the 2019 Galaxy Tab A does not include the Lift to wake feature, Samsung continuously updates and improves its devices, and it is possible that future models may incorporate this functionality. In the meantime, users can explore alternative options, such as compatible cases or the Double tap to wake feature, to automate the process of waking their tablets.

The Tab 4 7.0 has an Auto Wake setting but not Auto Sleep
The Samsung Galaxy Tab A can be woken up by swiping up from the Clock screen and selecting the Do Not Disturb icon, followed by Sleep. However, the Tab 4 7.0 model has an Auto Wake setting but lacks the Auto Sleep function. This means that while the device can be set to automatically wake up when the cover is opened, it will not go to sleep on its own when the cover is closed.
To enable the Auto Wake feature on the Tab 4 7.0, users can go into the "General" settings and select "Device Manager" from the left-side menu. Under "Device Manager", they should tap on "Accessories" and then enable the "Book Cover" option. This will allow the case to unlock the screen or automatically wake up the device when opened. However, it is important to note that a screen lock setup will nullify the Auto Wake option.
The absence of the Auto Sleep feature on the Tab 4 7.0 means that users will need to manually put the device to sleep by setting a screen timeout or using the power button. This can be a minor inconvenience for users who prefer the convenience of automatic sleep when closing the cover.
It is worth noting that some third-party cases or flip covers for the Tab 4 7.0 may advertise automatic sleep and wake functions. However, these cases may not work as expected due to the lack of a proximity sensor on the device. As a result, users might need to manually activate the sleep mode or wake up the device using the power button or preset screen timeout settings.

The Tab A 2019 lacks a proximity sensor, which is available on older models
The Samsung Galaxy Tab A 2019 does not have a proximity sensor, unlike older models such as the 2016 version. A proximity sensor is a non-contact sensor that detects the presence of an object, often referred to as the "target", when it enters the sensor's field. This is used in phones to detect accidental touchscreen taps when the device is on a call and is held to the ear. The sensor emits a beam of electromagnetic radiation, such as infrared, or an electromagnetic field, and looks for changes in the field or return signal.
There are two main types of proximity sensors: inductive and capacitive. Inductive proximity sensors can only detect metal targets as they utilise an electromagnetic field. When a metal target enters the electromagnetic field, the inductive characteristics of the metal change the field's properties, alerting the sensor of the presence of a metallic object. Capacitive proximity sensors, on the other hand, are not limited to metallic targets and can detect anything that can carry an electrical charge.
Proximity sensors are available in models that can detect ferrous and non-ferrous metal objects, and in capacitive models to detect non-metal objects. They are also available with environmental resistance, heat resistance, chemical resistance, and water resistance. Proximity sensors are suitable for use in locations where water or oil is present, and they can be used in a wide temperature range, typically from -40 to 200°C.
To wake a Samsung Tab A 2019 from sleep, you can try using a tablet cover. Go into the settings, scroll down to advanced features, and then press accessories. From there, you will see Automatic lock, which you can set to "on".

Try test-running your tablet in safe mode to see if the sleep mode issue continues
If your Samsung Tab A is having trouble waking up from sleep mode, you can try test-running your tablet in safe mode to see if the issue persists. Safe Mode temporarily disables all third-party apps, so if the sleep mode issue continues, it's likely a hardware or firmware problem.
To enter Safe Mode, follow these steps:
- Power off your Samsung Tab A.
- Press and hold the power button until the Samsung logo appears on the screen, then release the power button.
- Immediately after releasing the power button, press and hold the volume down button.
- Continue holding the volume down button until the device finishes restarting.
- Once your device has restarted, "Safe Mode" should appear in the bottom left corner of the screen.
Now, test your device to see if it wakes up from sleep mode. If it does, the issue is likely caused by a third-party app. You can then restart your device to exit Safe Mode and begin uninstalling apps, especially those that you installed right before the sleep mode issue started.
If your tablet still won't wake up from sleep mode in Safe Mode, it's likely a hardware or firmware problem. In this case, you may need to bring your device to a repair shop or a Samsung service center for further diagnostics and repair.
Additionally, there are a few other things you can try to address the sleep mode issue:
- Check if you're using a cover with a magnet/sleep feature. Some covers have a magnetic sensor that will shut down the screen when closed or flipped open and flat against the back of the tablet. Try using the tablet without the magnetic cover or with a different case that doesn't have this feature.
- Ensure your tablet's settings are optimized. Go to Settings > Advanced Features > Accessories. Press it, and you will see Automatic lock. Set it to 'On'.
- If you're using an S-pen, try disabling Samsung's AirView service. This has been known to cause sleep mode issues when using certain apps.
If none of these solutions work, you may need to perform a factory reset on your device. However, make sure to back up your important data before proceeding with a factory reset.
