Track recording inaccurate despite high accuracy of GPS
I have an issue with the track recording on my phone:
When I cycle with my bike and record a track and my display from the phone is off then I got very wrong track lines. (Screenshot LocusMap 1.png)
On the Screenshot you can see I have good GPS Signal all the time (max was 5,5m). But the trackpoint is so inaccuracy. I mean it shows an GPS accuracy of 3,3m but my trackline is around 100m away from the real path which I drove.
How is this possible that my GPS accuracy is 3,3m at this trackpoint but my trackline is so much far away from the real path?
I drove the same track again but this time with Display always on. And the Track was perfect in my eyes. (Screenshot LocusMap 2.png)
Now I´m asking you what can I do that my Trackline is always like the Screenshot LocusMap 2.png but with display turned off. I mean I need to save battery for longer trips.
I think it is maybe something with the battery managment of Android (HyperOS)-
My Phone settings and LocusMap 4.29 settings:
Phone: Poco X6 Pro 5G
OS: HyperOS 2.0.104.0 (Android 15)
Track Recording:
distance interval: 8m
time interval: 5s
distance AND time
required GPS accuracy: 20m
Auto Pause: off
recording only during motion: off
GPS Settings:
Location filter: small filtering.
NMEA Recording: only for track recording
I did everything as described in the article:
https://docs.locusmap.app/doku.php?id=manual:faq:gps_lost_fix_android6
Autostart: ON
Battery restriction: OFF
App permission Location: all the time on
every permission for LocusMap is activated/allowed
LocusMap is locked in RAM with the lock
LocusMap runs as Service
In the developer settings of the phone I also activated "force full GNSS measurements"
I tested A-GPS reset many times.
I also tested it with the GPS Locker app. Also this app has all permissions and no battery restrictions. but unfortunately without success.
I googled a lot and also ask ChatGPT a lot for Tipps what I can do to get better accuracy tracks. But without any succes.
maybe someone can help me please?
The same problem 
I remember my Huawei Tab M5 was BRUTALLY violating all seetings you mention above, just to be perfect in battery savings - which it was.
Maybe HyperOS is "HYPER" in this regard, too?
With Galaxy (very old, old and latest Androids), LG (older Android) and Moto (older Android) I did not see differences between screen on and off.

I can see your "Battery restriction" setting is turned off but your inaccuracy sounds exactly like when I forget to turn off "Battery restriction"/ sleep apps/ deep-sleep apps etc.. Find there very detailed Locus knowledge base page on turning off power saving and check twice. It took me a long time to find all the related settings on my phone. Best of luck.
