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.)

That's interesting to hear that it's happening to you too. What version are you running now?
It seems that someone else also mentioned the issue on XDA a few weeks ago. I apparently am too new to post links, but it's a thread called "Bad GPS signal with Zenfone 7" from user Meuro986.

This is not a know issue
First you should factory reset your phone without restoring a backup file. You may still backup your images, SMS and so on but don't restore any backup file.
If it's still not working, then downgrade to A10.
If it's still not working, then send in for repair.
if it works with A10, then upgrade to A11 again and check if it's working.
if it works after A11, then install all your apps
if it stopped working with A11, then please let me know and we will try to find out why

Hi Anders,

Thanks for the reply. I did a factory reset and had the impression it was okay again, but that turns out not to be the case.

How do I downgrade to A10? Happy to check that next. Cheers!
