Recently I have noticed my device if often very slow to wake up, the screen remains blank for several long seconds (maybe tens of seconds, I never measured it) and the notification LED turns yellow.
I am not sure if this is related to the recent EA release of 5.0.0.73 or some other issue, I have tried to observe what happens over a USB cable with htop but was unable to catch the behaviour like that.
Any pointers on how to investigate this more are very welcome.
(I have rebooted and hard reset the phone all to no effect)
I have that sometimes on my XA2.
Rarely, like once over 2 month.
I panic, frenetically press everywhere, it does nothing, i wait, it works .
No idea from where it comes, though.
Currently it is happening multiple times every day, my gut says that it happens when the phone is not plugged in an there is no program running preventing deep sleep, but I can’t prove that without knowing how I can document what was running when I was trying to unlock the phone.
Wait, during phonecalls? How does that work? How do you even know there’s a problem?
If you did not reset the device it could well be that some stray, maybe recurring process is taking up all resources. The battery drain would speak for that, too. Use something like Crest or htop+ssh to analyze.
I use a bluetooth headset, wanted to see the time or activate the flashlight during the call for whatever reason.
I tried to turn on htop and nothing happened while it was running, the paranoid in me is starting to get worried about malware, the other side says I didn’t do any meaningful changes to the phone recently to incur this.
And it doesn’t tell you what causes these wakeups?
In that case - in any case really - you might want to enable persistent logging (I’d reboot just to be sure) and check what is happening there.
FWIW, lipstick is usually the #1 consumer on my phone, at least while idle.
Not voicecall-ui -prestart though. It just sits in the background at basically 0% CPU/RAM.
So unless you were using it while measuring - hmm, how does powertop work actually? Does it collect data over a long time?
WRT journalctl, yes, it logs a lot of uselss crap and it’s really hard to see the relevant stuff sometimes. I recommend using | grep -v ... to filter some of it out. Should work for journalctl -f too.
