Ryske

DUDU-Meng

You can only refresh one at a time. You can try both.

DUDU-Meng first one with 1 in the name works for 2 days then gps went off after. Second one installed never worked

What does “valid for 2 days, GPS off” mean?
Does it mean the GPS will work fine for two days?

Ryske

DUDU-Meng its worked for 2 days, mean gps could connect and weather service. Then it stops after 2 days without me doing anything

The system version you are currently using is the November 2025 release. After upgrading the display driver, the GPS functioned normally, but two days later it could no longer acquire satellites. Is that correct?
When satellites cannot be acquired, does restarting the system restore functionality?
Prior to upgrading the display driver, did the GPS consistently fail to operate properly with the new system version?
Could you please capture the ylog for me?

Ryske

DUDU-Meng yes it stops and doesn't work since that. Restart doesn't fix the issue, even a reflash doesn't fix the issue.
Before updating gps worked for a week after fresh rok install. Then one day it stopped and never worked back again.
I can capture any Log you need i did that before i can redo it.

DUDU-Meng

Ryske Could you please provide the YLog? Thank you.

Ryske OK

Ryske

DUDU-Meng no feedback?

The log has been analyzed by FYT, and the results only indicate weak GPS signal. The specific cause cannot be determined.
We also reviewed all system modifications made to 7862 within the past year and found no unexpected changes.
Do you have any additional evidence or patterns of occurrence for the issue?
Is this intermittent or consistently weak?

@Ryske - does your head unit network connectivity run off hotspot or cell sim?

I don't have a GPS issue but there's definitely a network related bug in the weather service widget. Although I don't pay much attention to the root cause, I believe it usually fails when cell service from dudu7 sim gets dropped while driving. It does not revive weather connectivity when cell service magically reconnects again 3-5mins later. When i start my car in the morning i will first be connected to home wifi so I don't think widget stability is an issue at that point. Im running 905 OS version.
