Maps (GPS) is showing inaccurate location in iphone 16pro max

Its been 4 months since I purchased the Iphone 16 pro max. But I am unable to use the most basic feature which is Maps. The map is not showing accurate location whether its Iphone Maps or google maps. Already registered a case for this and visited the service centre .Formatted the phone multiple times in service centre and waited for multiple updates but the issue still persist.

Being a flagship phone and unable to help me with the most basic and important feature is disappointing for me. I use my 5 year old realme

phone for location while travelling as this phone doesn't help me there.
