Input.location GPS issue

Hello, I am using Input.location to get longitude and latitude on Android devices. It perfectly works on a Galaxy S7 (Android 7.0) but not with OnePlus 6 (Android 8.1). They both had GPS enabled, same permissions, I try FINE_LOCATION and COARSE_LOCATION but it returns completly wrong longitude and latitude on the OnePlus 6 and the right coordinates on the Galaxy S7 (it's the same build/APK). It's it an Android issue ? Am I missing a permission ? I don't know where to look anymore.. Thanks
