Programmers from Google, who successfully converted the Linux operating system to Android, constantly emphasize the optimized mechanism for working with storage devices in the description of their development. In particular, it is indicated that, thanks to a number of improvements, the user is unlikely to ever see the message “low RAM”. In fact, fabulous promises were embodied only on paper. In reality, owners of devices running Android are in some way or another able to decide how to free up memory on Android. In this paper, we will give a number of recommendations to partially eliminate this problem. But first, take a short tour of the terminology of the operating system from Google.
RAM specifications
If you do not go too deep into the nuances of the system, then in android devices two types of storage modules are used: RAM (operational) and ROM (permanent). For example, we open the description of the characteristics of the MultiPhone 3540 smartphone and read: the amount of RAM - 512 MB; built-in - 4096 Mb. Here, the first number indicates RAM, and the second indicates ROM. Operational is very fast, but when you turn off the power or reboot, all its contents are deleted. The larger the volume, the more applications can be launched at a time. This is currently the most important feature. The type of chips used (DDR-1,2,3, etc.), as in desktop computers, has not been disclosed by manufacturers, therefore you cannot select a smartphone by this parameter. It is not yet possible to increase the volume by installing additional microcircuits or slats in the device, as is done in full-fledged computers.
Checking available megabytes
The question "how to look at RAM" is quite natural. In the Android system, this can be done in several ways. We list them:
1. Call the application menu and proceed to the "Settings". Here, in the “Applications” section, you should open the “Working” tab and add up the two numbers below, marked as “Busy” and “Free”.
2. Read the specifications for the device, which indicates the amount of RAM.
3. Use third-party applications. For example, the Antutu Benchmark test suite information block shows RAM. You can also recommend the Clean Master program , which, when you click on the inscription “RAM”, not only displays the available and total volumes, but also allows you to free up RAM on the “Android”.
In general, listing applications that can show the megabytes of RAM installed in the device is a thankless task, as there are hundreds of them. The last two programs are quite enough.
Memory Check Features
We consider it our duty to warn that in some cases owners of android devices who know how to look at RAM have problems trying to solve this problem on cheap Chinese-made smartphones and tablets that externally copy brand models. Craftsmen from the Middle Kingdom managed not only to change information about the installed version of the operating system, but also to correct data from memory. As a result, a device with 256 MB of RAM is in the vast majority of programs defined as a model with several gigabytes, which often causes application malfunctions. In such cases, the characteristics of RAM can be determined only by alternately installing information programs, hoping that one of them will gain access to real data. Or, through the test launch of "heavy" applications, which for their work just require all that huge declared volume.
The nuances of using
If the owner plans to simultaneously launch several applications, actively using multitasking, it is important for him that as much RAM as possible is installed in his smartphone model. Otherwise, you may encounter a message stating that the Android RAM is full, or with a significant drop in performance due to the need to automatically remove / launch unused programs. For example, the popular Viber telephony solution, when installed and running, constantly takes at least 30 MB of memory for its work. Various "ICQ", "Skype", mailbox questionnaires and even the "Market" client itself - all this "hangs" in the RAM, "eating off" its piece from the common pie. If there is a lot of memory, then no problems arise. However, with its lack, the performance of the operating system is seriously reduced. The cleaning mechanism begins to unload unused sections of code, but since the user needs all running applications, the release process does not stop even for a minute. In “running” cases, an error and overflow message may even be displayed.
How to free up valuable device resource with settings
One of the most effective ways that answers the question “how to free memory on Android” is to use the provided capabilities of the operating system itself. Many programs can be disabled by the user through the settings. It is important to understand what can be turned off and what is required for the system itself to work.
To access the function, you need to go along the path "Settings - Applications - Application Management - All". A list of programs appears. Some of them work in the background, consuming device resources. For example, even such a seemingly harmless application as the JetAudio audio player, without being specially launched, works hiding from the user. Perhaps this decision of programmers allows you to speed up the launch or implement some other functions, but for devices with a small amount of memory, this is simply wasteful. Justice can be restored in a few seconds. How to free memory on Android in a similar situation? Very simple! It is enough to click on “JetAudio” in the list, and then, on the screen that appears, on the “Stop” button. This operation can be done with all unwanted applications. The advantage of this method is that you do not need any root-rights that are necessary for the work of many third-party cleaning programs. True, after a reboot, everything will return to its original settings, which should be remembered.
Alternative to basic settings
Of course, the above method is not the only answer to the question of how to free memory on the "Android". So, the program "Autostart" expands the possibilities of configuration. After its launch, the user will see a window in which the sections are given, when you click on each of them, access to the correction is opened for him. The most interesting item is “After Boot Boot”. Opening it, you can see a list of programs that automatically start and, with a high degree of probability, are further partially located in RAM. By clicking on the “liked” record, you can prohibit its downloading by the corresponding command. Again, you need to understand the tasks of applications and utilities, and not mindlessly disable everything.
Great cleaner
Perhaps no less well-known solution that allows you to release valuable RAM in real time is the free application for Android - Clean Master. After installation, you need to run the program through the shortcut in the "Applications". Next, you need to select the “Acceleration” item and follow the recommendations issued, carefully reading the warnings, otherwise you can easily erase movies from the memory card or disable root access (if any).
Warning
Some programs that can be disabled through the basic settings or in another accessible way are part of the operating system, and when they are unloaded from memory or disabled, malfunctions can occur. Thus, we recommend that you perform such manipulations primarily with your own installed software packages. In any case, with a lack of RAM, the best solution is to purchase a device in which more memory is initially installed.
