How can I check which CPU chipset do I have? I want to check if I have a Snapdragon or Exynos chipset. How could I check this quickly? I need this info because I plan to root my phone, and it matters, exactly which chipset the phone has.
I have tried to find this info inside the phone, but no luck.
Do I need to install some app, or can I get this info without additional software, by reading it somewhere inside the phone?
First you'll need to find your device's Model Number.

You can find this in Settings > About Device, under the field Model Number.

It may look something like: SM-G930F.

If your device is in a state where you cannot navigate to Settings > About Device, please refer to the bottom of my post for alternative methods to lookup your model number.



Once you've found your model number, you can look up its chipset in my source, or in the tables below:
