In Tomtom App for Android, is there anyone else who has encountered that the GPS location is off by 20 or 30 feet? I have tried downloading a GPS app and then downloading GPS data but its not really working, has anyone got a solution?

The accuracy depends on number of satellites used/ found, and most dedicated GPS units state an accuracy of between 3 to 10 metres.
You will have to use a theodolite to get the accuracy you may be looking for.

What type of location are you at when you see the discrepancy? A more rural area will be less accurate due to fewer cell towers, etc. A very dense urban area with many buildings will also be less accurate due to the buildings interfering with the satellite reception, etc.
