Modern mobile devices are becoming increasingly resource-demanding, and the issue of free space comes to the fore for most users. When your smartphone starts to run slowly, apps crash, or the system reports critically low storage levels, the first thing you need to do is diagnose it. Understanding where to look for memory on Androidallows you to quickly free up space and extend the life of your gadget without purchasing new equipment.
Many owners confuse two completely different types of memory: random access (RAM) and internal (ROM). The first is responsible for the performance of running processes here and now, and the second is for storing your photos, videos, applications and system files. In this article, we will analyze in detail the paths to settings on different versions of the operating system and shells from manufacturers, so that you can easily find the information you need.
Menu interfaces may differ significantly depending on whether you have Xiaomi, Samsung or pure Android from Google. Despite the visual differences, the logic behind the layout of the settings remains similar, and knowledge of the general principles of navigation will help you navigate any device model released in recent years.
Main differences between RAM and built-in memory
Before delving into the settings, it is important to clearly distinguish between concepts, since optimization methods for them are radically different. Random Access Memory (RAM) works as a short-term buffer: the more it is, the more applications can run simultaneously without rebooting. When you close the app, the data in RAM is erased.
Internal memory (ROM or ROM) is your digital warehouse. The operating system itself, instant messenger cache, gallery and downloaded files are stored here. It is this type of memory that is most often filled to capacity, causing error messages when trying to take a new photo or install an update.
⚠️ Attention: Never try to clear RAM with third-party “task killers” on an ongoing basis. The Android system itself effectively manages RAM, and forced unloading of processes only increases battery consumption when they are restarted.
Some budget models use virtual expansion technology, when part of the internal storage is reserved for RAM needs. This can be confusing during diagnostics, since the available ROM capacity will be artificially reduced for the sake of performance.
If your phone starts to slow down, first check how full the internal memory is. When less than 10% of the space is free, the system automatically slows down the operation of the data storage controller.
Checking storage in pure Android and Google shells
On line smartphones Pixel and devices with minimal interface changes, the path to memory information is as simplified as possible. Manufacturers strive to make the settings intuitive, hiding complex technical details from the average user.
To access statistics, you need to go to the menu Settings. Next, scroll the list down to the Storage (Storage) section. In some firmware versions, this item may be located inside the tab System, but most often it is included in the main list of settings.
Opening this section, you will see a visual chart showing the distribution of space. The system automatically categorizes data: applications, images, video, audio, etc. By clicking on any category, you can study in detail what exactly is taking up space and delete unnecessary files.
- 📊 A general summary shows the percentage of occupied and free space.
- 🗑️ The "Free up space" button suggests deleting duplicates and rarely used files.
- 📂 Folder detailing is available through the additional settings menu.
It is worth noting that in pure Android the cache system is considered separately from application data, which allows you to more flexibly manage cleaning without losing important information such as logins and passwords.
Interface features in the Samsung One UI and Xiaomi MIUI shells
Large manufacturers often rework the standard settings menu to suit their corporate style, which is why finding the right item may take longer. In the ecosystem Samsung with shell One UI the logic is slightly changed for ease of use with one hand.
Galaxy owners need to go to Settings, then select item Device maintenance (or Device care). Inside this section there is a tab Memorythat shows the status of both the internal storage and RAM in one place. This is convenient for a comprehensive assessment of the health of a smartphone.
Users Xiaomi, Redmi and Poco with a shell MIUI or HyperOS face an even more aggressive optimization system. Here the section is called About the phone or is available through the app Security -> Cleaning. The system immediately offers to delete “garbage”, but it is important to carefully look at what exactly it is proposed to erase.
| Brand / Shell | Path to settings | Features display |
|---|---|---|
| Samsung (One UI) | Settings -> Device maintenance -> Memory | Single dashboard for RAM and ROM |
| Xiaomi (MIUI/HyperOS) | Settings -> About phone -> Storage | Aggressive cleaning recommendation |
| Google Pixel | Settings -> Storage | Detailed breakdown by file type |
| Huawei (EMUI) | Settings -> Memory | Separate tabs for internal and external memory |
It is important to understand that item names may change with firmware updates. If you do not find an exact match, look for synonyms: “Storage”, “Storage”, “Disk” or the chip icon.
Hidden system partitions
In some shells, up to 10-15 GB can be occupied by the “Other” or “System” section. This space is reserved for updates, swap files and the system cache, which cannot be deleted manually without root access.
Diagnostics of random access memory (RAM) through the developer menu
The standard settings menu often shows only the total amount of free RAM, without revealing details about which processes are consuming it. For deep analytics, you need to activate the hidden section for developers.
Activation occurs through the menu About the phone. Find the item Build number (Build Number) and quickly click on it 7 times in a row. The system will ask for your PIN code or pattern, after which a notification will appear that you have become a developer.
Now a new section will appear in the main settings For developers. Inside you need to find the item Memory or Running Services (Running services). Detailed statistics are displayed here: how much memory is occupied by the system, how much by applications and what is the average amount of free RAM for the last 3, 6 or 24 hours.
⚠️ Attention: Do not change the background process limit settings in the developer menu if you don't understand the consequences. Artificial limitation can lead to unstable operation of instant messengers and loss of notifications.
This tool is especially useful if the phone gets hot or discharges quickly. You will be able to see the parasitic application that is consuming resources even in the background and forcefully stop it.
The Developer Menu is a powerful diagnostic tool, but use it carefully. Changing parameters without understanding the essence can disrupt the stability of the OS.
Using third-party applications for monitoring
When the built-in tools are not enough, specialized utilities from the store come to the rescue. Google Play. They provide more flexible widgets on the desktop and advanced statistics in real time.
Popular solutions such as CPU-Z, AIDA64 or DevCheckshow not only the amount of memory, but also its type (LPDDR4X, LPDDR5), frequency and temperature of the sensors. This is critical for enthusiasts and gamers who monitor device throttling.
However, you should be careful with "All-in-one Cleaners" class applications. Many of them themselves consume a significant amount of resources and display intrusive advertising. It is better to choose highly specialized system monitors that work in the background with minimal energy consumption.
- 🚀 CPU-Z - a classic for checking hardware and current RAM load.
- 📈 DevCheck —provides detailed graphs and widgets in the style of science fiction.
- 🧹 Files by Google —the official application for smart storage cleaning without unnecessary garbage.
When installing such apps, always check the permissions. The memory monitor doesn't need access to your contacts or microphone. If an application asks for something unnecessary, this is a reason to remove it and find an analogue.
☑️ Safe installation of the utility
Working with an SD memory card and transferring data
If the internal storage is full, and the smartphone model supports microSD cards, this becomes a salvation. However, Android treats an external card in two ways: as portable storage or as an extension of internal memory.
In portable storage mode, the card is visible as a separate disk. You can transfer photos, videos and music there manually or through the settings of a specific application (for example, camera). But the applications themselves and their heavy data often remain on the internal drive.
The "Adoptable Storage" function allows you to format the card so that the system perceives it as one with the internal memory. This solves the problem of lack of space globally, but makes the card unreadable on other devices and slightly reduces the overall speed of the phone.
Settings -> Storage -> SD card -> Settings -> Format as internalBefore formatting, be sure to save all data from the card to your computer, as the process will completely destroy all information on it. Also, use only high-speed cards of the U3 or V30 class so as not to slow down the system.
⚠️ Attention: The speed of the memory card is always lower than the speed of the built-in flash chip. Do not install heavy games or applications that you use constantly on the SD card, otherwise you will encounter long loading times.
Regularly check the status of the card through the storage settings. Flash memory has a limited rewriting resource, and timely replacement of the media will protect your data from sudden loss.
For photos and videos, it is best to set up automatic saving to an SD card in the Camera application settings. This is the easiest way to save internal space without risking system operation.
Frequently asked questions about memory management (FAQ)
Why does the memory fill up by itself after cleaning?
This is normal system behavior. Applications create a cache for quickly loading pictures and content, and instant messengers save received media files. The system also creates log files and updates. It is recommended to clear the cache once every 1-2 months, and not every day.
Is it possible to delete the Android folder on a memory card?
It is strictly not recommended to delete the entire folder Android entirely. Application data (obb and data) is stored inside it. Deleting will reset game settings, loss of progress and map cache. Delete only specific folders of deleted applications.
How to learn how much memory is occupied by system files?
Go to the storage settings. Usually the "System" or "Other" item shows this volume. If it takes up more than 20-25 GB on a modern smartphone, there may be leftovers from old firmware updates that can be deleted through the Recovery Mode menu.
Does filling the memory affect Internet speed?
Directly - no. However, if the memory is filled to 100%, the browser will not be able to save the page cache, and applications may load data incorrectly, which is subjectively perceived as slow network operation. Freeing up space will improve the responsiveness of the browser.
Is it safe to use applications to speed up memory?
Most of these applications provide a temporary effect. They forcibly close processes, which the system immediately starts again. This wastes battery power. It is better to use the built-in optimization function in the phone settings.
