| Stability Type |
Log Requirement |
Catch Way |
| 1.Crash |
Full crash dump |
|
| 2.SystemReboot系统启动 |
Logcat, kmesg, tomestone |
如下： |
1.Logcat logs(main, events, radio)
2.Dmesg/kernel logs
3.bugreport and “dumpstate" log
adb shell bugreport > bugreport.txt
adb shell dumpstate > dumpstate.log
(this command will produce trace log about all process then u need adb pull /data/anr to collect the trace log) adb pull /d/binder/ .
4.Trace file /data/anr
5.adb pull /data/tombstones
(All log file time must be consistent with issue occurred time, it needs to clear /data/anr & /data/tombstones after stability issue occur)

| 3.System Freeze/ Touch panel freeze系统卡死/屏幕卡死 |
Logcat, kmesg |
如下： |
1.Logcat logs
2.Kernel logs: “ adb shell getevent” 实时事件log
open echo w > /proc/sysrq-trigger when capture dmesg and bugreport log as follows:
adb root
adb remount
adb shell
echo w > /proc/sysrq-trigger
& then exit adb shell, then collect bugreport
adb shell bugreport > bugreport.txt
adb shell kmesg > kmesg.txt 没有kmesg
3.Key events log
adb shell getevent -rtl /dev/input/event0 按键事件
4.bugreport and “dumpstate " log:
adb shell bugreport > bugreport.txt
adb shell dumpstate > dumpstate.log
adb pull /d/binder/ .
5.Dumpsys window log:
adb shell dumpsys window > dump_window.txt
6.Meminfo log:
adb shell cat proc/meminfo > meminfo.txt
7.Procrank log:
adb shell procrank > procrank.txt
8.Top log:
adb shell top > top.txt
9. Add below information:
•Adb workable or not, ANR or not
•CTP workable or not ->
touch screen and observe
the output of "adb shell getevent".
•Display driver workable or not ->
Use the screencast to see
if the screen can be displayed
•Power key/volume key work or not?
Menu/back/home key work or not?
10. It's better to trigger a ram dump
Before test:
adb root
adb shell "echo 0x843 > /d/spmi/spmi-0/address"
adb shell "echo 0x80 > /d/spmi/spmi-0/data"
Then long press power key more than 10~30s
could trigger a dump.
If device is rebooted, it needs to set again.

| 4.Black screen 黑屏 |
Logcat, kmesg |
如下： |
Main, events, radio, bugreport, sumpstate, Procrank,
meminfo, top log
1.Logcat logs(main, events, system, radio)
2.Kernel logs
3.bugreport and “dumpstate " log
adb shell bugreport > bugreport.txt
adb shell dumpstate > dumpstate.log
then capture traces log :
adb pull /data/anr , after about I min ,
clear /data/anr and capture traces log once again
adb pull /d/binder/ .
5.Meminfo log:
adb shell cat proc/meminfo >meminfo.txt
6.Procrank log:
adb shell procrank >procrank.txt
7.Top log:
adb shell top >top.txt
