In the world of mobile operating systems, two years is an entire era. The gap between Oreo, released in 2017, and Oreo, released in 2019, seems insignificant only at first glance. In fact, this period was marked by fundamental changes in the way we interact with a smartphone: from gesture control to a deep redesign of the privacy system. Android 8.0 (Oreo), released in 2017, and Android 10, which was released in 2019, seems insignificant only at first glance. In fact, this period has seen fundamental changes in the way we interact with our smartphones, from gesture controls to a major privacy overhaul.
Many users still operate devices on the eighth version of the system, fearing updates or simply not seeing the point in them. However, the transition to Android 10 brings not just new wallpapers, but critical improvements in the security architecture and optimization of background processes. Let's see why the difference between these versions can be a decisive factor when choosing a new gadget or deciding to update the current one.
Android 10 became the first version to officially abandon sweet names in favor of digital numbering, which symbolized the maturity of the platform. If the eighth version focused on stability and the implementation of Project Treble to simplify updates, then the tenth version relied on user privacy and intuitive control without buttons.
Interface evolution and navigation
The most noticeable difference that the user encounters immediately after the update is the navigation system. The classic three-button layout reigned: “Back”, “Home” and “Applications Menu”. It was convenient, familiar, but it took up precious space on the screen and required a mechanical press (or its emulation). Android 8 The classic three-button layout reigned: “Back”, “Home” and “Applications Menu”. It was convenient and familiar, but it took up precious space on the screen and required mechanical pressing (or its emulation).
With the advent of Android 10 Google introduced a full-fledged gesture navigation, which became the de facto standard for the entire industry. Swipe or buttons, freeing up space for content and making interaction on large screens more natural. Now going back is done by swiping from the edge of the screen, and switching between applications is a simple move up.
⚠️ Attention: Switching to gestures in Android 10 requires an adaptation period. If you are updating from an old version, you may experience difficulties with your usual actions in the first couple of days.
In addition, in the tenth version, the power menu has been completely redesigned. Long pressing the lock button now causes not only shutdown, but also quick access to smart home and digital wallets. In the eighth version, this functionality was either absent or implemented through third-party add-ons from manufacturers.
The visual style has also undergone changes. Android 10 brought a system dark themethat works at the level of the entire interface and supported applications, saving battery power on OLED screens. In Android 8 dark theme was rare and depended solely on the goodwill of the developer of a particular application.
Notification management and communication channels
Notifications are the nervous system of a smartphone, and this is where Android 10 made a huge leap forward compared to its predecessor. In the eighth version, Google introduced notification channelsfor the first time, allowing you to sort alerts by category. However, managing them remained quite cumbersome and required a deep dive into the settings of each application separately.
In Android 10 management became instant and contextual. Now, when you receive a notification, you can long press on it and immediately choose: hide such messages, mute the sound, or completely block notifications from this application. This radically changes the user experience, eliminating information noise without the need to climb into the jungle of menus.
- 🔔 Priority notifications: Android 10 now has the ability to mark conversations as priority so that they are displayed above others even in Do Not Disturb mode.
- 🎨 Live replies: the system offers contextual actions directly in the curtain notifications, for example, copy a confirmation code or open a link.
- 🔇 Flexible sound control: The volume sliders have become more detailed, allowing you to separately adjust the sound of media, calls and alarms.
Another important innovation is pop-up windows for calls. In Android 8 an incoming call often covered the entire screen, interrupting the current task. In Android 10 calls from third-party applications (messengers) are displayed in the form of a neat banner on top, without interfering with the use of the phone.
If you are annoyed by constant notifications from games, in Android 10 you can configure them to automatically hide after 15 minutes of inactivity, which was not the case in Android 8.
Privacy and data security
Privacy issues have become central to the development Android 10. If Android 8 just began to introduce restrictions on background activity of applications, then the tenth version put strict barriers to access to personal data. Now, apps can't access your location, camera, or microphone unless you're currently using them.
The key difference is access to storage. A Android 8 applications often requested access to the entire internal storage, which allowed them to scan all your files. Scoped Storage (limited storage) Android 10 isolates application files from each other. The photo editing app will only see photos, but will not be able to read your documents or correspondence in instant messengers.
| Security function | Android 8 (Oreo) | Android 10 |
|---|---|---|
| Access to location | Only “Always” or “Never” | “Only when using” |
| Access to background | Partially limited | Complete blocking of access to camera/microphone |
| Device identifiers | IMEI and serial number available | Access is restricted, resettable ID is used |
| Encryption | Full disk encryption | File-level encryption (FBE) |
In addition, Android 10 restricted access to immutable device identifiers such as IMEI and serial number. Apps are now issued a resettable ID number, which is reset to zero when the settings are reset, making it difficult for ad networks to create a permanent digital footprint of the user.
⚠️ Warning: Some older apps developed for Android 8 may not work correctly on Android 10 due to tighter file permissions.
What is Project Mainline?
This is a Google initiative launched with Android 10 that allows key security components to be updated through Google Play, bypassing smartphone manufacturers. This means that critical security patches arrive faster, even if the phone manufacturer has abandoned support for the model.
Performance and power management
Under the hood Android 10 lurks a significantly more advanced resource management system. The eighth version used a mechanism Doze to save energy, but it only worked when the phone was lying still. In the tenth version, the algorithms have become more aggressive and smarter: the system forcibly limits the background activity of applications that you rarely use.
Adaptive battery - a feature that debuted in Android 9 and was brought to mind in Android 10, uses machine learning to analyze your habits. If you open an app only once a week, the system will severely limit its running in the background, saving battery. In Android 8 such intelligent energy distribution did not exist in principle.
It is also worth noting the work with RAM. Android 10 better manages unloading applications from RAM, storing in memory only what the user really needs right now. This leads to the fact that even on devices with 4 GB of memory, multitasking feels smoother than on similar devices with the eighth Android.
☑️ Checking battery optimization
Compatibility and application support
The compatibility gap is growing every year. Although most popular applications still support Android 8, developers are increasingly focusing on the API of new versions. This means that the latest features in instant messengers, banks or games may simply not appear on your device if it is stuck on an old version of the OS.
Android 10 brought native support for foldable smartphones and improved work with external displays. If you plan to use the phone in conjunction with a monitor or docking station, version 8 may not provide correct interface scaling or audio transmission.
In addition, new security standards in banking applications often require fresh security patches, which are practically no longer released for Android 8 . Using an outdated OS for financial transactions becomes risky.
⚠️ Attention: Check the list of supported applications in the official Play Market. Some new apps may require a minimum version of Android 9 or 10 to install.
Android 10 provides more stable operation of modern applications thanks to up-to-date libraries and security standards that are missing in Android 8.
Final comparison and recommendations
To summarize, we can say that Android 10 —this is not just an evolutionary update, but a qualitative leap in convenience and security. Upgrading from version 8 will give you a dark theme, convenient gestures, smart notification sorting and, most importantly, protection of your personal data from intrusive applications.
If your device technically supports updating to Android 10, it is definitely worth installing. The only reason to stay on Android 8 is the use of specific industrial equipment or very old hardware that physically will not support new processes, but in the segment of consumer smartphones there are almost no such cases left.
Remember that support Android 8 from Google has officially ended, which means there are no security patches for vulnerabilities, discovered after 2020. In today's digital landscape, this is an unacceptable risk.
Is it possible to downgrade from Android 10 to 8?
Technically this is possible through flashing (Flash), but the process is complex, requires unlocking the bootloader and leads to complete data loss. In addition, this will void the warranty and can turn the phone into a “brick” if there is an error.
Frequently asked questions (FAQ)
Will I lose data when upgrading from Android 8 to 10?
When updating over the air (OTA) through the phone settings all your data (photos, contacts, applications) are saved. However, before any major update, it is strongly recommended that you make a backup to your Google Account or to your computer in case of unexpected failures.
Will the phone run slower after the update?
In the first 24-48 hours after the update, the system indexes files and optimizes applications in the background, so there may be slight heating and increased battery consumption. After that Android 10 usually runs faster and smoother thanks to improved memory management.
Is it possible to bring back navigation buttons in Android 10?
Yes, it is possible. Go to Settings → System → Gestures and select classic navigation mode. However, you will lose part of the screen space that the buttons occupy.
Does Android 10 support split screen mode?
Yes, in Android 10 Split Screen mode has become more convenient and accessible through the recent applications menu. Android 8 also had this feature, but it was more difficult to activate.
