There are few things more annoying than when you’re paying attention to something on your cell phone and the screen turns itself off because you haven’t touched her in a long time. And, if you don’t have Smart Lock or similar, you may have to enter the PIN code again or use the fingerprint.
To solve it we will see how you can keep your Android phone screen on First, by changing the settings in Android and from the developer settings Then, I’ll show you how to do it with an application to make it easier to switch between the always on and normal display mode.
Increases waiting time
Ideally the mobile would keep the screen on until you turn it off, like the TV, but there’s a problem: is the component that drains the battery the most. The way to tackle this problem that most operating systems have encountered is to set a timeout from which the screen will turn off by itself. On Android, this timeout is usually 30 seconds.
If you don’t touch the screen during standby, it turns off by itself.
That is, Android keeps the screen on even if you don’t touch it for those 30 seconds, although from the second 20 the brightness is reduced. If you touch the screen at any time, the countdown starts over. This setting can be changed in the settings, and is sometimes called waiting time or time out.
To change the timeout you need to open the Android Settings application and then go to Display section. It should appear there, although the setting in question may change place in other customization layers. If you have trouble finding the setting, use the search box within the settings.

The configurations can vary from one mobile to another, but generally you can choose a band that goes from 15 seconds to 30 minutes. Choose the one that suits you best, although if you choose a high number, remember to turn off the screen manually, because it not only uses up the battery quickly, but it can also burn the image.
Keep the screen on while it is charging
The normal Android setting does not allow you to keep the screen always on, but you can from the developer settingsat least while the phone is plugged in. These settings are hidden by default, so you must activate them first. The way to do this has not changed for years: go to Android Settings, section device information, y play seven times over the compilation number.

A text alert warns you that the developer options are activated, and to enter them you need to retrace your steps, in the Settings, this time entering the System. Here you will find the Options for developersand one of the first on the list is Display always on when loading.

It’s not possible to enable this option without loading the device, so if that’s what you’re interested in, you’ll need a third-party application like the one below.
Use Caffeine to keep the screen on
If none of the previous sections solves your ballot, you will always have Google Play. There are plenty of applications there whose sole purpose is to allow you to keep your screen on. One of the most up-to-date is Caffeine, which can be used as a quick fix on phones with Android Nougat or higher.

Caffeine
After installing it you will notice that, surprise, it does not appear in the application drawer. That’s because it only works as a quick fix, allowing you to keep the screen on more easily. In order to use it, you need to add your quick fix firstby displaying the notification panel and tapping on the pen icon (note: the method may be slightly different on customization layers). Then, drag its icon, which is a coffee cup.


Now, the screen will remain active indefinitely and regardless of whether the mobile is charging or not. If at any time you want your phone to behave as usual, that is, the screen turns off by itself, just retrace your steps and deactivate it in the quick settings of Android.
