How to clean your Android phone thoroughly: erase all trash safely

New year, new life, they say. And this also concerns the mobile: nothing like doing a thorough cleaning to leave it glowing in the face of 2020. Now, it is convenient to know the operation of the phone to perform the cleaning safely, if there can be no problems. And that we have proposed today: we will eliminate all the garbage so that your Android is as clean as if it were new again.

We will proceed step by step to adapt the level of cleanliness to your needs. As we ascend the cleaning will be deeper; And, with it, there will also be certain side effects. So, before proceeding with the deletion, you should make a backup of your smartphone, including photos, messages, and contacts.

Our first recommendation is clear: do not install applications that promise to wipe out all the garbage on your phone. Much of these apps get the opposite effect: instead of wiping your phone will end up dirtying advertising, they will slow down and can even infect you with malware. Go very carefully.

Remove apps you don’t use

This point is basic: the first step of any cleaning must be to end the superfluous. That is all those applications that you installed “just in case” and that in the end are occupying unnecessary space on the phone. They can even consume data and battery even if you have never opened them.

Do not have contemplations: finish with everything you do not use. Apps that have become unused, games you tried one day and ended up staying on the phone, take out everything that has no direct utility for you. Your phone will thank you (and you too).

Goodbye to the WhatsApp gallery

After unused applications, the gallery left by WhatsApp and company messages is the element that accumulates the most trash of the entire phone. Because does that ton of photos with funny memes that send you from the three hundred groups in which you signed up really serve you? The same goes for videos: to the garbage container. And without going through recycling.

To delete the WhatsApp gallery you have to do the following:

  • Access the reel of the application (it is in a folder called the same as the messaging app, inside the gallery) and review the content in case there is something you want to save. It is always good to make sure.
  • Once you have saved what is important (if there is anything), do not have mercy and delete the folder. In case you can’t do it from the gallery, use a file manager.
  • To prevent WhatsApp from automatically downloading multimedia content to the gallery, preventing it from being filled again with “garbage”, you just have to go to its settings and enter Data and storage. Leave “No file” selected to download with mobile data, Wi-Fi and roaming. This will only save what you download manually.

Remember to make frequent cleaning of the folders in the gallery where the photos of the chats are stored: they tend to become huge.

Delete unwanted photos and videos

At the previous point, it’s time to take a look at the gallery to eliminate everything you don’t want to keep. Screenshots (it is a must-see folder), images that you only used to share promptly and videos that have lost all meaning: if you do not think they are really worth it, it is best to remove them from your mobile. Also, if you have a cloud backup of all the content you can also delete some photos and videos that interest you from the phone. Having a secure backup will free up a lot of mobile space.

Make sure that after deleting the photos and videos, they do not remain in the recycle bin: there are custom layers that do not directly delete the content just in case you would like to recover it (the quarantine is usually one month). Enter the settings of your gallery, access the recycle bin and completely eliminate what you do not want.

Clear cache yes or no?

Usually, the application cache is usually considered as system garbage, but this is not entirely true: thanks to that cache all apps can boot faster since they store content that they do not have to generate again. Now, not all apps behave correctly with the cache as there are real storage eaters. Google Chrome and Facebook are two good examples.

Our recommendation is that you do not delete cache unless the application has saved too many MB and you really need the space. Check the settings of the most controversial apps (Chrome, Facebook, Instagram or Twitter, for example) and, if spread, delete your cache: the option is in the storage settings.
