Many users confuse the model number with the firmware version. It is important to distinguish between these concepts: the model is the “hardware”, and Android is the “soul” of the device. We will help you understand the nomenclature and understand how to make the most of the capabilities of your smartphone.

Determining the current version of the operating systemThe first thing you need to do before any manipulation is to find out exactly what is installed now. Often in the settings only the build number is displayed, but not the Android version. To get complete information, you need to go to menu Settings → About phone → Software information.

Here you will see the line “Android version”. It is this number that tells you what applications are available to you. If you have an older version, many modern banking applications may no longer work correctly. The check takes only a few seconds, but gives a complete understanding of the situation.

Also pay attention to the date of the security update. Even if the Android version does not change, security patches may arrive regularly. This is important for protection against viruses and network vulnerabilities.

⚠️ Attention: The build number (for example, A750FNXXS5CTK1) contains encoded information about the firmware release date, but does not always match the Android version. Look specifically at the "Android Version" field.

Write down the current build number before updating. If the new version turns out to be buggy, you can find the exact version to roll back through Odin.

Software evolution in different generations of Galaxy A7

The line Galaxy A7 was released in different years, and each generation received a different number of updates. Samsung revised its support policy, so older models remained on earlier versions, and new ones received more attention.

The 2015 model (A700) was originally released on Android 4.4 KitKat and received an update to 6.0 Marshmallow. This was the limit for this device. Owners of this model should already think about replacing the gadget, since support has long been discontinued.

The situation with the 2016 model (A710) was similar: it started with 5.1 Lollipop and ended with 6.0 Marshmallow. But the 2017 model (A720) became more successful: it received the Samsung Experience interface. This allowed the device to remain relevant longer. Android 8.0 Oreo and the Samsung Experience interface. This allowed the device to remain relevant longer.

The most advanced was Galaxy A7 2018 (A750). It came out on Android 8.0 and has been updated to Android 10 with One UI 2.0 skin. This is the maximum version for the entire A7 line. Further OS updates are not expected.

Compatibility table of versions and models

So that you do not have to look for information on the forums, we have prepared a summary table. It shows which Android is the latest for each modification of the Galaxy A7.

As can be seen from the table, Galaxy A7 2018 is the only device in this line that received Android 10. All other models stuck to earlier versions. This is important to consider when purchasing a used device.

If your model is not listed or has a different index (for example, the Chinese version), the information may differ. Always check the device region in the service menu.

Instructions for updating the system

If you find out that an update is available for your device, you can install it in two ways. The first and easiest is via the Internet. Make sure the battery charge is above 50% and Wi-Fi is connected.

Go to Settings → Software update → Download and installation. The system itself will check Samsung servers. If an update is found, follow the onscreen instructions. The process may take from 15 minutes to an hour.

The second method is through a computer and a app Smart Switch. This method is more reliable if the over-the-air update is interrupted or an error occurs. Connect the phone to the PC with a cable, launch the app and click "Update".

⚠️ Attention: When installing the update, do not disconnect the cable or remove the battery (if it is removable). This may lead to permanent damage to the system partition.

Features of the One UI shell on the Galaxy A7

For owners of the 2018 model, updating to One UI was a significant change. The interface has become more convenient for one-handed operation. The main elements have moved to the bottom of the screen.

One UI brought night mode to all applications, improved gesture controls and a new notification center. Visually, the system began to look more modern and lighter. Animations have become smoother, although this is not felt everywhere on 2018 hardware.

Also a function appeared (later renamed Modes), which allows you to automate the phone's actions. For example, turn on silent mode when connecting to your home Wi-Fi. This is a powerful tool for increasing productivity. Bixby Routines (later renamed Modes), which allows you to automate phone actions. For example, turn on silent mode when connecting to your home Wi-Fi. It's a powerful productivity tool.

However, it is worth remembering that new features require resources. On older versions of hardware, One UI may be slower than the lightweight Samsung Experience. If you notice slowdowns, you can try reducing the animation in the developer menu.

What to do if there is no update

If you are the owner of a Galaxy A7 2015, 2016 or 2017, official major OS updates are over for you. This doesn't mean the phone can't be used, but you need to be careful.

• 📱 Clean up memory: Older versions of Android don't cope as well with full storage. Keep at least 10-15% of memory free.
• 🛡️ Security: Without the latest security patches, do not open suspicious links and do not install applications from unknown sources.
• ⚙️ Optimization: Do this periodically resetting the settings to factory settings to remove accumulated software garbage.

There is an alternative way - installing custom firmware (Custom ROM). Enthusiasts are porting newer versions of Android to older devices. However, this requires unlocking the bootloader, which will void the warranty (if it is still valid) and may lead to malfunction.

For most users, the best solution would be to carefully use the current version and promptly replace the device with a more modern one when the necessary applications stop working.
