Many times we complain about performance problems on our phones out of sheer ignorance. Today almost all Android-based customization layers allow us to alter certain settings in order to make the phone work much better. One UI, Samsung‘s personalization layer, is a good example of this.
When we have faced notification problems on mobile phones from Huawei or Xiaomi we have given you a trick that allows you to keep the affected app open in the background so that it continues to work normally. This also improves performance since you do not have to open the app from scratch every time you access it. Of course, if you have countless apps open in the background, the opposite effect will be achieved because the RAM consumption will be higher and the processes of the mobile will take longer to run.

This option is also present in Samsung mobiles, although much more hidden.
Block apps from multitasking
To keep apps open and blocked on Samsung phones , what we have to do is access the multitasking of the device, either by sliding your finger from the bottom to the center of the screen or pressing the corresponding button if you use the virtual controls.

Click on the icon of the app that you want to leave blocked in the background and, in the drop-down that appears on the screen, choose the last option, called “Keep open for quick start”. This way you will see that the preview of the app is fixed with a padlock.
This will mean that, for example, if you use WhatsApp, Chrome and the notes app at the same time, you can set them in the background and access them immediately thanks to the fact that they do not have to be opened from scratch continuously, improving the overall performance of the system.
To unlock them, all you have to do is open the multitasking panel again and click on the padlock icon. It will disappear and when you click on “Close all”, all the apps in the background will be removed from memory.
Aspects to consider
Of course, this is a great advantage as long as we use it wisely because, as the advertising slogan says, “power without control is useless.” As we have previously said, if we keep all the apps we use blocked , it will mean a greater memory consumption that, in the long run, will make the mobile work worse by having so many apps running in the background.

Of course, although the consumption is not very high, the more apps we keep open , the more battery they will consume on the smartphone. So again we recommend you use this tool with your head and, when you finish your activity, re-release the apps so that they close normally when cleaning them from multitasking.
It is possible that data consumption will also be affected if we continue with several of these apps running at the same time.
