DIY Android cleaning: tips and apps

Who has never had to deal with slowing down their phone ? It is known, after a few years, any smartphone begins to send signals of failure, mainly caused by constant use and by the high number of files saved inside.

The causes of a slow phone, however, can be different and it is not always necessary to resort to extreme remedies, such as changing the battery or even the whole device. Actually, small tricks are enough to free up some memory and lighten everything!

The most common solutions
The Android operating system , as well as all the others on the market, with the passage of time can suffer some blows, slowing down. The reasons can be different:

a large number of installed applications;
applications that run in the background and consume continuous resources;
little free memory left available;
an unoptimized update.
Any device, despite not just leaving the store, can be speeded up . Surely the first useful step is to make a nice internal cleaning , starting with moving applications and data to a MicroSD card . Since not everything can be moved, what is not needed is better to eliminate it.

The first apps to evaluate are, in fact, those that work in the background, or the main ones responsible for the sudden interruption of some games . To check which ones have the greatest impact on the use of batteries, you can request the help of Wakelock Detector , which has the precise function of identifying those applications that weigh most on the speed of the operating system. Once detected, simply delete them and the problem will be partially solved.

To stop, however, the functioning of the apps in the background, you can use Greenfy , which allows you to identify the apps in the background and to stop their operation when they are not used. Finally, for those who are passionate about games and can’t stand being slowed down or stopped, the best remedy is Game Booster , an application that puts the operation of the apps in the background in standby while you are playing .

Other small tricks can concern the widgets running : if you don’t really need them, it is always useful to delete them, because they take up space and slow down the other operations. Even the animations can be a problem that can be solved by going to Settings> About phone> Build number , and click until it shows the message “Now you are a developer” . At this point, you have to go back to Settings> Developer option again and deactivate the three items corresponding to Drawing .
In general, however, the best solutions always remain the same:periodically empty the cache, delete unnecessary files and applications, move some of them to the Cloud or MicroSD to optimize space and make use of valid apps. Let’s go into detail.

  1. Periodically clear the cache
    All Android devices maintain a cache that allows you to more easily access the data most frequently viewed and retrieved by the installed apps. The more time passes, the more the cache size increases : apps like Spotify , for example, also take up more than 1 GB of memory for cache management, since they can also be used in offline mode.

Getting rid of the contents of the Android cache, so annoying, is really easy: just go to Settings> Storage> Cached data . Obviously, this is a short-term solution, since the data will continue to be displayed and, therefore, the cache will grow again. Periodically emptying it, however, certainly helps to improve the situation.

  1. Delete unnecessary files and applications
    On an Android device, the space available seems to be never enough : between system updates, installed applications, the amount of photos and videos saved in memory, often even a 64 GB capacity can be insufficient.

One solution would be to delete unnecessary files and unnecessary applications , starting with evaluating what takes up the most space. Finding out is simple: just go to Settings> Memory . The space occupied is grouped by type of content and, by clicking on it, it will be possible to view how much space each individual app occupies.

The new Android 8.0 allows you to leave the operating system itself the task of identifying those superfluous elements that, therefore, can be safely removed. All this makes the operation easier and you will have no doubts about the usefulness of what you are going to delete.

DiskUsage for checking the available space
In the event that you are no longer able to synchronize e-mail (an almost complete saturation index), just go to Memory> Cached data and empty it completely.

To check how the space is occupied , it is useful to rely also on the DiskUsage app which, at startup, performs a complete scan of the contents of the internal memory of the device. It is not recommended, however, to delete unnecessary files using the app itself, opting for other solutions; DiskUsage, in fact, is designed to provide an idea of ​​the state of things and not to intervene directly on it.

Remove the preinstalled app
Generally, apps installed by default on a device are not removable, unless you root the device . If this last step has been done, then you can install the free System App Remover app , useful for uninstalling the pre-installed apps. If root has not been done, pre-installed apps can simply be disabled by following these steps:

install the Driver ADB and Minimal ADB and Fastboot software on a Windows system;
restart the system and connect the Android device via USB;
open the Minimal ADB and Fastboot folder (C: \ Program files (x86) or in C: \ Program files) on the Windows system;
hold down the SHIFT key , click with the right mouse button in a free area of ​​the Minimal ADB and Fastboot folder and select Open command window here ;
type adb devices to make sure that the device has been recognized;
type adb shell pm list packages to view the names of the installed apps;
once you find the app name, type adb shell pm hide package_name and reboot your mobile device.
If in the future you would like to make the disabled app available again, simply repeat the procedure using the command adb shell pm unhide package_name .

  1. Optimize space with MicroSD and cloud
    A simple, fast and effective method to optimize the space of a device involves moving apps and files to other “containers” such as MicroSD and cloud .

Move photos and videos to the cloud
Moving photos and videos to the cloud is a valuable contribution to freeing up space on a smartphone. The app that best manages this process is Google Photos .

The space available on Google’s servers is unlimited , as long as you accept a 16 megapixel scaling for photos and a reduction of 1080p resolution for videos. You can also make a backup keeping the original size, but it is evident that the space is destined to decrease considerably.

Google Photos is equipped with the Free Space feature , which automatically recognizes photos and videos that have already been backed up, deleting local copies and maintaining access to them from the app gallery.

Move apps from internal storage to MicroSD card
Another space-saving operation for Android phones is to move the installed apps from the internal memory to the MicroSD card . Before buying one, it is good to evaluate its specific techniques , so that it is quite capacious and offers another data transfer speed. Definitely, it is best that it is at least class 10 and UHS .

In addition, Link2SD is also very useful: it is a function that allows you to create a link with the app moved to the SD card , so that the operating system believes that it uses an app stored internally but, in reality, located elsewhere.

The most common apps
The cache has been emptied, files and apps have been moved to MicroSD cards and to the cloud, cleaning has been done correctly but the phone insists on going in slow motion. It can happen and there is no need to despair: Android has made available to users a series of easily downloadable apps that can come to its rescue in a few simple steps!

  1. SD Maid
    SD Maid is the ideal app for tidying up an Android smartphone and it’s free, simple and efficient.

The main screen contains 4 different functions , one of which is paid and not immediately visible:

Remnants of applications: scan the device and detect old files left by uninstalled apps;
System cleaning: quite explanatory, it completely cleans the system;
Clean: it is used to optimize the database.
Through a side menu you can view an overview of the device, from all the installed apps to the latest changes made, up to a tool that allows you to manage any duplicates in the address book.

  1. Files Go
    It is one of the applications made by Google thanks to which you can:

view the least used apps among those installed;
clean up the system cache;
eliminate duplicate or multimedia files of WhatsApp and Telegram that clog the memory.
It also enjoys a file manager that shows data divided by category and offers the possibility to send files between multiple devices with a simple click.

All-in-One Tool Box
It comes with modern and simplified graphics, which allows you to clean up and speed up in no time without a smartphone. The main screen immediately shows the percentage of space occupied on internal memory, RAM and SD card and, simply by clicking on Free , it will be possible to gain space by emptying the cache and deleting unnecessary files.

The All-in-One Tool Box app allows you to close the services running in the background thanks to the Speed ​​up option while, through the Tools function , you can manage the installed apps, make backups or reset files and disable previously installed apps.

History Eraser
It’s a handy enough tool to clear your app cache, clear recent calls, sms and browser history, and manage the settings of other Google apps.

The History Eraser interface is absolutely navigable and simple to use. By accessing the settings, you can activate the auto-start of the app when the smartphone is turned on, the app icon in the notifications menu and the Cleaning mode with a touch via widget.

Avast Cleanup
The application developed by AVAST Software in Prague, known for the free antivirus of the same name for various devices, is suitable for more thorough and accurate cleaning . The first screen performs a quick scan of the device memory looking for unused files and apps in the background. In the end, you have the option to start cleaning or select advanced settings to manually choose what to delete and what to keep.

With Avast Cleanup, you can also move files to the cloud instead of deleting them . Doing so is very simple: in a few steps you can configure online storage and keep your smartphone memory free. Unfortunately it is an app that provides a short free trial period: subsequently you need to sign up for an annual subscription in order to use it.

System App Remover
Another efficient Android cleaning solution is the System App Remover app ; requires the presence of a root (i.e. a permission) in the phone to access the most advanced settings of the device.

This small free software allows you to uninstall apps, manage applications in memory and delete unwanted files.

There is also a paid Pro version that does not require root: after installing it easily, it will allow you to scan the memory, find too heavy files, uninstall too old apps and empty the device cache.
