Newbie here, so be kind! :)

Got a new Android phone (a China-made G9 4G, not a very popular brand, claimed to be running "stock" Android 7.0). I've been looking at its logcat output to see if there is anything I can improve - like bad settings, frequently erring-out apps, etc.

I'm a bit concerned right now because I've seen quite a few errors that recur rather frequently; specially this one, that appears every 5-10 seconds or so:

231 512 E MAL-RDS : ( rds_ru_3gpp_status_ind, 1603) [RDS-E][RU][EVENT_RU_DM_3GPP_STATUS_IND] Invalid u43gpp_status:0x8

Googling showed me that this is quite common as background noise (in samples like this, this and this); however I yet didn't come up with anything that discusses this particular error.

Just wanted to know if any of you know what this error means, and how to remedy it.

Here's a considerable chunk of my logcat, in case the rest of the context would help (although often there's no context between two of the above error instances):

Oh, and would certainly appreciate it if you can point out the causes for any other errors appearing in the above as well :) The stacktraces are from a known data usage tracker app, but the crashing EasService was something I noticed just now (before posting this).
