CPU-Z is one of the best android application for advance users. It gives us hardware/software details like Sensors/CPU/GPU, etc. of phone in which the app is installed. These types of details are generally not mentioned in phone.
we use different apps to check the phone’s root accecc, bootloadet but using this app we can directly check the root access as well as bootloader.
So friends if you are a advance user , I highly recommend you to use this app.
Thanks
