Are you trying to smooth up the Android experience on your Samsung Galaxy S7? If you are looking in speeding up your phone and in optimizing the battery life along with the general performance, we might have to best solution for you and for your device. Thus, we’re going to show you how to replace the default Android system with a new super-fast and minimal Android 8.0 Oreo based custom ROM – the new release of the Toxic platform that uses the framework-res APK of Android Nougat but is based on stock Android 8.0 Oreo.
Well, this new build of Toxic ROM can be now successfully installed on your Samsung Galaxy S7. So, in a few words you can test a new update opportunity that was made available by those of xda-developers – in that respect, we must thank xda senior member davecotefilm for this update tutorial. Anyhow, as already outlined above, this new Oreo powered firmware might be just perfect for your Galaxy S7 as it brings lots of tweaking possibilities along with a pure-like Oreo experience that can be now safely used on a daily basis.
Toxic 8.0 ROM for Samsung Galaxy S7 is a stable and smooth Android software that will help you receive better performance from your smartphone. Overall, the battery life will be optimized, the speeds will be increased and the Android UI smoothed up. You will get rid of unnecessary apps and bloatware and you will be able to use the latest Android 8.0 Oreo features, apps and capabilities along with extra tools that cannot be experienced by default within the stock Android OS. Bottom line, the Toxic 8.0 platform is a great alternative for the Samsung built-in system, especially if you are an advanced Android user.
Of course, this is not an official Android firmware related by your OEM – it cannot be OTA received on your Galaxy S7 and you cannot associate it with Samsung or with Google in any manner. In fact, the Toxic ROM represents a free aftermarket distribution of Android Oreo which is only based on the stock Android firmware. This is a custom ROM that’s developed by third party devs and which can be only manually installed on your phone – yes, Samsung KNOX will get tripped, so you risk in losing your phone’s warranty and access to built-in apps (the warranty flag can be restored only if you choose to reinstall the stock Android software via Odin).
Additionally, the Android 8.0 Oreo based custom ROM can be flashed only after you prepare a few other things on your Galaxy S7. You will have to gain root access on your Samsung branded device before doing anything else and you will have to install a custom recovery image within its system as the actual flashing process can be resumed only if a custom recovery environment can be used – note: we recommend TWRP recovery as your custom recovery choice.
A Nandroid backup should be considered as it can help you avoid further problems. This particular backup operation can help you secure the Android OS that runs on your Galaxy S7. Thus, if the new Toxic 8.0 ROM will not perform as you expected, you can afterwards choose to flash the Nandroid backup package and go back to stock.
Along with that particular backup solution you should also save your personal data, info, account and files – everything that wasn’t there from day one might get corrupted or wiped out while the update operation is completed. Therefore, choose to use Samsung’s built-in cloud storage services, sync your data with your Google Account or just download backup and restore apps from Google Play before doing anything else. Only in that way you can save your contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, EFS folder, IMEI / NVRAM data and so on.
For being able to apply the steps explained below you will have to use a computer. On this computer you must set up the right drivers of your Galaxy S7 – you can use the Samsung KIES toolkit for being able to do so. Also, on your smartphone you must become a developer which can be done by tapping repeatedly on Built Number: after 7 or 10 taps the ‘you are a developer’ message will be restored. Finally, on your phone you have to enable Developer Options, a field that’s located under ‘Menu – > Settings – > Developer Options’.
It’s imperative to verify the power that’s left on your handset before choosing to begin the Toxic 8.0 custom ROM update operation. If your Galaxy S7 is running low on power you can end up in soft bricking its Android system – it can happen only if you phone will get turned off right in the middle of the update process. So, be precautious and plug in the charger first, if the power that’s left is currently lower than 50%.
