How to Prevent Screenshot Or Screen Recorder in Android?

In some situations, we don’t want to allow to take screenshots or screen recordings of our android application. Here we are going to explain how to prevent Android from taking a screenshot or screen recording when the app goes to the background. Generally, when we take a screenshot, we will see a Screen Capture notification in the notification bar and you can see that screenshot in the Gallery app if you click that notification. And some of the android application we can’t take a screenshot of the visible screen because of the screen secured by the developer. In this situation, we’ll see the message in the notification bar or in the Toast over the screen. Some of the payment transfer apps or course-containing apps have this feature. In this article, we’re going to create a simple project to demonstrate how this feature works. A sample GIF is given below to get an idea about what we are going to do in this article. Note that we are going to implement this project using the Java language.

3 Ways to Stop Android Phone Screen From Turning Off Automatically

How many times it happened to you when you try to read something on your phone and the screen goes off? Screen timeout is the setting on your phone which automatically turns off the display in order to save the battery. Since Android phones are completely customizable this setting also has some options to choose from, and on some phones, you can even completely turn it off. So, here I am telling you the ways to stop the phone screen from turning off. Read on!

Stop Phone Screen from Turning off Completely

Table of Contents

If you want to completely turn off this setting then there is an option in the display setting. If you don’t find the option to turn it off, don’t worry we have another trick up our sleeve to tell you about.

1. Via Display Settings

1. Pull down the notification panel and tap the little setting icon to go to Settings.
2. In the Settings menu, go to the Display and look for the Screen Timeout settings.

3. Tap the Screen Timeout setting and select the duration you want to set or just select “Never” from the options.

If you won’t see the Never option in the settings but you still want to keep your device awake for longer then follow the next method.

2. Via Developer Options

1. Go to Settings > About Phone > tap on Build Number 7 times.
2. Navigate back to Settings > System > Developer Options.
3. Look for Stay Awake option and enable it.

Now while your phone is on charging, the screen will not turn off automatically unless you remove the charger. In that case, the default setting will enable which you selected in the display setting.

3. Via Third-party Apps

You can also prevent your phone screen from turning off completely using a third-party app. There are plenty of such apps available on the Play Store, and we are using “Caffeine”. Here’s how to use it:

1. Download and install Caffeine – Keep Screen On from the Play Store.

2. The app works via a toggle, so you will need to add this to the Quick Settings panel.

3. Pull down the Quick Settings panel and tap on the Pencil icon to edit it.

4. Now look for the Coffee Mug icon among all quick settings.

5. Move this “Caffeine” toggle to the Quick Settings panel by holding and dragging it.

7. When the toggle is in the main Quick Settings panel, you can use it anytime.

Whenever you want to change the screen timeout time, swipe down to open the Quick Settings, and tap the Coffee Mug icon. By default, it sets screen timeout to Infinite, but it also has a number of other customization options.

Wrapping up

This is how you can make your smartphone screen never go off while you are reading something important on it. Tell us in the comments, which of the above-mentioned ways will you use to increase screen timeout on your phone.

How to Prevent the Screen from Turning on with Notifications on Android

One of the biggest drawbacks for many mobile phone users occurs when the screen turns on when receiving notifications . An option that in some mobiles is deactivated but in many others it is activated, where the problem comes and causes that even if we do not touch the mobile, when a message or notification from any apps reaches us, the screen wakes up.

In many aspects this will depend on the user’s tastes, if we prefer that the screen is activated with the notifications or not, but nevertheless we must take into account several things that happen on our mobile when having the option activated. A better possibility may be the Always on display mode, although not all of them are smartphones that integrate it.

Is it bad that the screen turns on with notifications?

There are no serious drawbacks for which we decide to stop having the screen activated with each notification , although nevertheless there are small buts that can encourage us to remove the option. All these reasons are the following, which you will have to put on a scale to choose if you prefer to activate or deactivate it.

The first and most important thing is that by turning on the screen continuously it consumes more battery and in turn, it is causing it to wear out, which in the long run will end up taking its toll. On the other hand, it can also be annoying for the entire screen to light up in the dark.

How to turn off the screen with notifications on Android

By default on Android phones that do not have any customization layer, the option is very simple. It does not usually come activated, although in some cases we can come across this or have configured it this way by mistake. Once decided to change it, we just have to do the following:

• We access the Android mobile Settings.
• We touch on Screen.
• Now we look for Lock screen.
• And finally we deactivate the option called “Activate screen if there are notifications”

Prevent the screen from turning on on Xiaomi phones

The Xiaomi brand is one of the manufacturers that for years had the option to wake up the screen with alerts activated by default, although little by little it has been modifying in MIUI 12. To modify it in our smartphone, we will only have to enter Settings > Lock screen and uncheck the option “Activate lock screen for notifications”. Something quick and easy that has changed in recent times.

Configure Huawei phones to not turn on the screen

Another of the manufacturers that from the beginning usually turns on the screen with each notification is Huawei, although we will also be able to deactivate it with a quick option in all versions of EMUI. In this chaos you just have to go into Settings> Notifications> More notification settings and we have an option that affects the entire system to Activate or deactivate the screen.

Options in Samsung to not turn on the screen

By default in Samsung mobiles with One UI there is no option that causes the screen to turn on when receiving notifications, which is a reason for joy so that we do not have the aforementioned problems. However, they will appear on the Always On Display screen that is present in so many Samsung smartphones and more and more.

If we want to remove the notifications from the Always On Display screen of our Samsung mobile, we only have to do these steps:

• We enter Settings.
• Click on Notifications.
• We deactivate the option “Show in Always on Display”.

Prevent the screen from turning on on other mobiles

In the rest of Android mobiles such as Motorola, LG, Vivo or Realme smartphones, this option is not activated by default and in many of them there is also no option that activates the screen with each notification . In some layers of customization it is being added, but removing it is as simple as we saw in the first step. We can also choose to write “activate screen” in the Settings in the search bar and the option we are looking for will appear directly.
