Is my "hal_process_report_ind: Bad item quality: 11" something to worry about?

Question

I get this error in LogCat while doing dev work. Sounds like a hardware malfunction. Is it? What's it in relation to? I tried searching but found only people talking about cameras. It's on a Motorola Razr M. My device acts quirky a lot (feedback delays often when unlocking and freezing temporarily while playing games) and I wonder if this has something to do with it. Thanks!

Answer 1

I seem to be getting no network location where I am currently at, and this message popped up in my log so suspecting this is part of my problem:

12-16 09:07:19.739  1117  1500 V GmsNetworkLocationProvi: onSetRequest: ProviderRequestUnbundled, reportLocation is true and interval is 0
12-16 09:07:19.739  1117  1117 V GmsNetworkLocationProvi: SET-REQUEST
12-16 09:07:19.739  1117  1117 V GmsNetworkLocationProvi: in Handler: ProviderRequestUnbundled, reportLocation is true and interval is 0
12-16 09:07:19.849   594   607 E qcom_sensors_hal: hal_process_report_ind: Bad item quality: 11 

This sequence pops ups twice while opening Maps, so I am pretty sure the quality message pertains to the location somehow, likely throwing the network location away.

It seems that is a bug related with the location: http://www.reddit.com/r/Nexus5/comments/20g0vj/150_linessec_qcom_sensors_hal_logcat_spam_causing/ and it seems that this is only triggered if you have have chosen not to enable location reporting. And once it happens it only stops after rebooting the device.
