Please tell us some basic information before asking for help: Model Name: ZS630KL Firmware Version: 18.0610.2106.156 Rooted or not: Nope Frequency of Occurrence: always when using GPS APP Name & APP Version (If your issue relates to the app): N/A ======================================== A while back I send my phone in for repair and the motherboard was replaced. Since I had a decent replacement phone for a while I didn't bother to switch back immediately after the repair. Last month I was on holiday/vacation where I traveled over 6500 km by car. I noticed the GPS was very slow to connect/fix, drop regularly and once connected the speedometer jumped up and down. I had to resort back to my backup phone for stable navigation. I noticed the accuracy is quite low and erratic (jumping between 10 and 30 or even 50 meters) and it doesn't seem to connect to a whole lot of satellites 10/12ish while my backup phone does 20-22+ under the same conditions. It's this perhaps a known issue with the software or is it more likely a hardware issue? I previously used GPS (before the repair) without any issue.
Hi @The PyroPath and @gabvigno, If you are still experiencing this here are some troubleshooting steps you can take: Make sure that Google Maps / Waze has location permissions set to 'Allow all the time'. Make sure Google Location Accuracy is enabled. (Settings -> Location) Clear cache files system-wide. (Settings -> Advanced -> Mobile manager -> Cleanup) Clear the cache of the LocationServices system app. Make sure both Wi-Fi and Bluetooth scanning is enabled in Location settings. If none of the steps above improve GPS performance and you haven't performed a factory reset, please do so.
