[Xperia10][3.3.0.16] Phone is unusable while biking

I've had my phone for a couple months and just started for the last few weeks to go biking with it. After just a few minutes of biking, the phone becomes unusable. The front LED is switched on with a green, blue or red light (I think I've seen them all). Nothing can be done until a reboot happens. This is major problem for me as I'm normally (outside Coronavirus confinement) commuting by bike every day :/

I suspected an issue with the fingerprint scanner getting activated in the pocket. But disabling the service didn't change anything. Or I thought maybe the sensors are getting wild due to the vibrations.

Here attached are the systemd logs from today. I started biking just after 16H13. I'm not sure what to look for in that amount of logs.

journal.txt.gz

The most suspicious item with its massive amount of occurences starting after that time is

dbus-daemon[2051]: [system] Connection ":1.34" is not allowed to add more match rules (increase limits in configuration file if required; max_match_rules_per_connection=512)

I'm not sure where this comes from exactly and how to investigate this further. Any help would be greatly appreciated.

Thanks

I can also confirm a problem the the Fxtec Pro1 while cycling. With the phone in a rear cycle jacket pocket, and attempting to obtain a PR on a long downhill, the phone can become ejected from the jacket pocket, resulting in bunch of phone parts on the road.

I can confirm some similar problem - it only affects the Xperia 10 but nuo the XA2. I am commuting with the bicycle 40km every day and the phones are either in my pocket or in a bag on the bicycle - in the pocket, they get wet and in the bag they are exposed to a lot of vibratoio. From time to time, the Xperia 10 ceases service during the ride (reboot, switching off, sensors (proximity and environment light sensor) cease working), while the XA2 is not affected. I know that there are subtle differnces between the OS of the two phones but the problems may also be caused by mechanical or electric problems.

The red/green led is associated with log lines like "compositor_stm_panic_timer_cb(): panic led triggered". Basically lipstick is too busy with something to respond in timely manner to display power up/down handling.

Also, those max rules warnings: in the log that Connection ":1.34" is lipstick, and the warnings could be related to lipstick <--> connman related ipc. At least I think some issues that caused such problems were recently identified/fixed, but as those have not been released yet - you could try if disabling wlan helps.

Just came back from biking and disabling WLAN beforehand did help! I think it is the first time I went biking without having any issue with my phone. I'll check in the coming days with more biking if this is a reliable workaround.

This would definitely be good enough for me until the next release which should fix it properly. I'll test it once it is out and update this thread with the result

Thanks a lot for your quick and correct reply!
