Choosing between Android 6.0 Marshmallow and Android 7.0 Nougat today is not just a matter of personal preference, but a fundamental decision that affects the security and compatibility of your device. Although both systems are already considered outdated by modern standards, understanding the differences between them is critical for users who are not yet able to upgrade to more recent versions or are buying used smartphones.
At first glance, it may seem that the difference between the generations is minimal, but under the hood operating system there are colossal changes hidden. The seventh version brought revolutionary innovations in multitasking, power management and a graphical interface, which were sorely lacking in Marshmallow.
In this article we will analyze in detail the architectural differences, analyze performance and find out which of these platforms copes better with modern tasks. You will find out whether it is worth bothering with searching for firmware or whether it is better to stay on the stable but limited sixth version.
Evolution of the interface and ease of use
Visual changes in Android 7.0 were not just cosmetic, they changed the very principle of interaction with the device. Unlike Marshmallowwhere notifications simply hung in a list in the curtain, in Nougat it became possible to respond to messages and perform actions directly from the notification panel without unlocking the phone. This saved users thousands of clicks per day.
Another revolutionary change was the split-screen mode. Now you could launch YouTube at the top of the display and open the messenger at the bottom. On the sixth version, this was impossible without obtaining superuser rights and installing third-party modules.
The settings have also undergone changes. In the seventh version, the menu became more structured, and search by parameters worked faster and more accurately. This is especially important for those who like to delve into the details of the configuration of their gadget.
⚠️ Attention: Split screen mode works correctly only on applications adapted by developers to the new version of the API. Old apps may not display correctly or be forced to close when trying to multitask.
It is worth noting that the transition to the new interface required getting used to. The clear recent apps button has moved, and the logic for working with quick settings has changed. However, after a week of use, most people no longer wanted to return to the old scheme.
Performance and optimization of resources
One of the main advantages Android 7.0 Nougat was the embedded compiler ART (Android Runtime) with JIT (Just-In-Time) support. The sixth version used only AOT (Ahead-Of-Time), which led to long application installations and took up a lot of space. The new compilation system made it possible to speed up the launch of apps and optimize the use of RAM.
Thanks to these changes, smartphones with 2 GB of RAM on the seventh Android worked noticeably smoother than similar devices on the sixth version. The system more effectively managed background processes, preventing them from “eating up” resources unnecessarily.
Technical details of the ART compiler
In Android 7, the application profile is collected in the background, and then the system decides which parts of the code to compile natively for maximum speed, and which to interpret. This reduces the load on the processor during installation.
The graphics subsystem also received an update to Vulkan API. This gave game developers the ability to create more complex visuals using less CPU power. If you love mobile gaming, then the difference in FPS between versions can be noticeable.
However, you should understand that optimization greatly depends on the device manufacturer. Some vendors changed the shell so much that the advantages of a clean system were offset by heavy interface add-ons.
Energy consumption and saving mode
The function Dozethat appeared in the sixth version, in Android 7.0 was significantly improved. Now it was activated not only when the phone was lying still, but also at any time when the screen was turned off, even if the device was in a pocket or bag.
This led to a significant increase in battery life. Users noted that smartphones began to live 15-20% longer in standby mode compared to the previous generation. Background synchronization of mail and messages was delayed until the screen was turned on.
| Characteristics | Android 6.0 | Android 7.0 |
|---|---|---|
| Doze mode | Only at rest | When the screen is off |
| Code compiler | AOT (slow installation) | JIT + AOT (fast operation) |
| Multitasking | None | Split screen |
| Graphics API | OpenGL ES | Vulkan + OpenGL |
In addition, in the seventh version it became possible to manually limit background activity for specific applications. You could go into the battery settings and prevent an unnecessary app from running in the background, which previously required installing special “freezers.”
For maximum energy savings on Android 7, go to Settings → Applications, select the unnecessary app and turn off the background mode. This will extend the battery life without uninstalling the application.
Security and data protection
The issue of security is where the gap between versions is most critical. Android 7.0 Implemented full file system encryption by default for all new devices. In the sixth version, this was optional and was often disabled by manufacturers to reduce the cost of devices.
A function was also introduced Scoped Directory Access, which allowed applications to access only certain folders, and not the entire storage. This significantly reduced the risk that malware could steal your personal photos or documents.
Security updates for the seventh version were released more often and contained more critical patches than for the sixth. Google was actively closing vulnerabilities in the system kernel that could allow attackers to gain full control of the phone.
⚠️ Attention: On devices with Android 6.0, support for most modern banking applications has already been discontinued due to the low level of security of encryption protocols.
It is also worth mentioning the “Find Device” function, which is in the seventh version began to work more stable and accurately determine the location even with a minimum battery charge. This is an important argument in favor of updating for those who often lose gadgets.
Compatibility with modern software
The compatibility gap is growing every year. Many popular instant messengers, social networks and banking applications are gradually increasing the minimum requirements for the OS version. If Android 6 still somehow manages basic functions, then Android 7 support lasts longer.
Game developers are also focusing on new APIs. Heavy projects may simply not run on an old system or run with critical graphics errors. Libraries required for modern services often require functions available only in Nougat and higher.
☑️ Check compatibility before purchasing
However, there is a nuance here. Some lightweight applications optimized for older devices can run even faster on the sixth version, since they are not overloaded with functions designed for powerful hardware of new systems.
Technical limitations and update nuances
Moving from one major version to another is always a risk. The firmware update process requires free memory space, which may not be enough on older devices with 8 or 16 GB of storage. Before installation Android 7 often you need to clear the cache and delete unnecessary files.
In addition, after a major update, the system optimizes applications, which can take from 30 minutes to several hours. During this time the telephone cannot be used. In the sixth version, this process was less resource-intensive, but also less efficient.
adb shell pm grant com.example.app android.permission.READ_EXTERNAL_STORAGESometimes after updating, users are faced with the fact that some functions no longer work correctly. This may be due to a driver conflict or incompatibility of custom shells. In such cases, a full reset to factory settings often helps.
⚠️ Attention: Before updating the firmware, be sure to back up all important data to your computer or to the cloud. The flashing process can lead to complete loss of information if there is an error.
Updating to Android 7 gives an increase in performance and security, but requires careful storage preparation and data backup.
Final summary: what to choose in 2026
To summarize, we can say that Android 7.0 Nougat is the undisputed winner in the duel with the sixth version. It offers the best balance between performance, functionality and security. Split screen, improved Doze and a new compiler make using a smartphone much more comfortable.
Staying on Android 6.0 makes sense only in one case: if your device does not physically support the update, and buying a new phone is not yet in your plans. In other situations, the desire for a newer version is justified.
Remember that the world of mobile technology does not stand still, and what was relevant a couple of years ago may become a bottleneck today. Choose the system that will provide you with access to the necessary services here and now.
Is it possible to officially update Android 6 to 7 on any phone?
No, the possibility of updating depends on the device manufacturer and model. Many budget smartphones have not received official updates to the seventh version due to weak processor characteristics or company policies.
Will the phone run slower after updating to Android 7?
On very old devices with 1 GB of RAM, the update may lead to slower performance due to increased system requirements. On devices with 2 GB of RAM and above, performance usually improves.
Is it safe to use banking apps on Android 6?
Most major banks have already stopped supporting Android 6.0 due to security vulnerabilities. Using financial applications on this version carries high risks.
What is Project Treble and is it available in these versions?
Project Treble is a modular architecture that simplifies updating Android. It was introduced only starting with Android 8.0 Oreo, so neither the sixth nor the seventh version of this technology is present.
