I need to view my device kernel info, in particular the architectures. The device is not rooted, therefore uname command isn't available in local terminal, but cat /proc/version doesn't have an option to increase verbosity (that I'm aware of) like -a for uname. Is there any other method I can use to see this information?

  • What device are you using? In most phones I have used, uname is installed by default. What information about the architecture do you want to access? – Reddy Lutonadio Aug 16 '19 at 17:25
  • The getprop command has a number of values that are related to the architecture. Check out getprop | grep abi. – Robert Aug 16 '19 at 18:13

If it's the architecture that you are looking in particular, then from the terminal you can type arch command.

You can also try CPU-Z to check the kernel architecture on its System tab.

Note : The assumption that uname is only found on rooted devices is unfounded. I have a device not rooted on Android 8.1 that has uname thanks to toybox.

  • arch is not available via adb on my phone (Sony XA2, Android 9). – Robert Aug 16 '19 at 18:09
  • @Robert toybox is not installed on your phone? Or is toybox installed but arch has not been packaged with it? – Reddy Lutonadio Aug 16 '19 at 18:27
  • Arctiic's question is about an unrooted device. Mine is unrooted, too. Therefore of course "toybox" is not installed. Installing such executables system wide plus PATH require a rooted device. – Robert Aug 16 '19 at 19:22
  • @Robert I think toolbox and toybox are part of stock Android, how would you get getprop and setprop without them. Nothing restricts apps executing /system/bin/uname -m or the uname syscall (including SELinux and seccomp). Also uname is part of every busybox release. Get one with Termux or place in /data/local/tmp and execute from adb shell. Multiple options. – Irfan Latif Aug 16 '19 at 19:46
  • @Irfan OK, you are right, there is a toybox and toolbox, however neither of them supports arch on my device (Sony XA2, Android 9 security update 2019-08-01). – Robert Aug 16 '19 at 19:53
