Just purchased this phone from lazada. Now I notice whenever I use the Google maps it doesn't shows my exact location. The blue dot will be very unstable and seldom shows my exact location. Is it my phone is defective or are they any other solutions for this. Other than that I'm happy with this phone performance. Thanks in advance.

Yup it's been set to high accuracy. Even while I'm standing outside its doesn't shows my exact location and driving also the same. Sometimes the big blue marker won't disappear even when it shows my exact location.
