GPS inaccuracy since beginning of May?

Please tell us some basic information before asking for help:
Model Name: Zenfone 7
Firmware Version:
Rooted or not: No
Frequency of Occurrence: Frequent
APP Name & APP Version (If your issue relates to the app): Google Maps, GPSTest, Strava
In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.
========================================
Since roughly the beginning of May, seemingly after a device update, I've had issues with GPS precision and accuracy. In the past, I was thrilled with how well the phone handled challenging circumstances, including Strava activity tracking through deep slot canyons (with strong track matching in both directions).
Now, I have major issues with tracking, which also extends to activities like using navigation in Google Maps: it sometimes hangs at an intersection and then I don't know how to proceed, being well past it. GPSTest will also show that it can't get a lock on location despite sattelites being all over the place.
Has anyone else experienced this? Thanks!

(here is a screenshot showing a failed Strava track as I walked down that street. You see that the track line jumps up and down and back and forth, when it should have just been a single, clean line to the right of the street.)

I don't know if that would help but if I were in such issues I'd try some GPS Test app which would "reset" GPS stuff, download correct AGPS data etc, I don't understand this area that well but I used to do that in the past on different phones, you can also use such apps to see sattelites visibility, GPS signal strength etc...if nothing you would at least have evidence for ASUS's devs that signal was fine 😉
I assume that you all have high accuracy set for positioning system, if not, switch it to this mode
I had issues with gmaps in the past on other phone/s and it was isolated to only a few apps, other were working fine and it was because of Google Play Services package (some versions were fine, some were causing issues you described) so if you somehow updated that package (sideloading etc) I'd downgrade it to "factory version" by uninstalling its updates and while you're there, disable battery optimizations for this package, for Google Services Framework and Android system, I did that for bunch of apps (also system apps as you can see) and I don't have any issues with GPS...I did that to get rid off missing notifications which somehow partially works
it all seems to me that ASUS fights with battery optimizations and many apps/processes gets affected by that and never/rarely ever wakes up and because of that we are facing different kind of issues

I have tried your method and have done so many tests but it doesn't work.
I still lose the gps signal with maps and waze.
It is hopeless, this phone is such a mess and asus doesn't give a damn about it.
Thanks anyway.
