Standard GPS and Assisted GPS (A-GPS) serve the same purpose — positioning — but work differently. While GPS relies purely on satellite signals, A-GPS uses mobile network data to speed up the initial location fix. Most smartphones use both systems together. When either fails, location accuracy and lock time are affected.
What Is A-GPS?
A-GPS is an enhancement to standard GPS that uses data downloaded over mobile or WiFi networks to predict satellite positions, dramatically reducing the time to first fix. Without A-GPS, your phone may take minutes to get a GPS lock rather than seconds. A-GPS faults are often software or network related; GPS hardware faults are more likely to require physical repair.
Common Causes of A-GPS Failure
- Disabled mobile data or location services — A-GPS needs a data connection to function
- Outdated A-GPS data — stale assistance data causes slow or failed fixes (resolved by clearing GPS data in settings)
- Failed GPS IC — if both standard GPS and A-GPS fail together, the hardware chip is suspect
- Corrupted firmware — a failed OS update can break location service APIs

At Pro-Logic Technologies, Kangari Building, Nairobi, the technician first addresses software and settings causes before proceeding to hardware diagnostics. Many A-GPS issues are resolved without any physical repair.
