How to change size of logcat buffer in Android?

Question

I noticed that the size of the logcat buffer varies on different devices. Assuming I have root permissions on my device, is there a way to change the buffer size of the main

Answer 1

See current buffer size

adb logcat -g

Set all type buffer size (main, system, crash)

adb logcat -G 16M # 16M can be replace by (128K ~ 16M)

Set specific type buffer size (main, system, crash)

adb logcat -b system -G 8M # system can be replaced with 'main' or 'crash'
