N8 GPS can't find my position

Question

Hello
I have a big problem with my N8 GPS. I just use Integrated GPS in positioning methods and I disabled A-GPS, Network and Wi-Fi options. But Ovi Map 3.04 can't find my position. I compare my phone with an N79 and a 5800 in similar situation. They can easily find the position in less than a minute! But my N8 still searching and searching…. . It’s embarrassing!!!
Can anybody help me?! Any suggestion?

Grrr ! All that "experts" here...
1, Use AGPS if you want to get a coarse estimation of your position.
2. Use internal GPS only if you want to get a precise position.
3. There are no (NO !) differences in position fix speeds caused by software. GPS works in a sequential way: A sequential data stream is sent by the satellites. To get a full position fix, all of that data stream has to be received, from start to end. THIS causes speed differences: If you start the GPS application at the beginning of the data stream, fix is fast. If you start it in the middle of the stream, the device has to wait for the stream starting again from the beginning. This is for collection "almanach" data - data about where the satellites are at present - they're moving.
4. If that almanach data was received earlier and no too long ago, GPS fix is fast because the device does not have to wait for that almanach data stream. Again: It has NOTHING to do with different software.
By the way: This is what AGPS does - downloading that almanach data via internet instead of waiting to get that data via the air and trying to triangulate your coarse position with the help of comparing the signal strengths received by different cell towers. Again: This does NOT provide you with precise positioning data - just estimations. Never use AGPS if you need a reliable position fix. .
5. GPS signals are high frequency signals. Reception of such signals may vary greatly with the phone's position: One or two cm of placing difference may cause a big change in reception.
6. GO OUT ! Do NOT try the GPS module indoors. You MAY get sufficient signal strength inside buildings - but this is an exception, not the rule.
7. N8s GPS receiver is really fine, very sensitive. No problem with that.
In short: Go outside. Don't use AGPS or network-based GPS. Don't believe people saying "Precise (!) GPS fix is much faster with software blabla..." Don't get fooled by a quick display of an estimated position: The real position fix did not get calculated at that point of time; it's still running in the background. This is what's causing that constant change of your position right after the first fix got displayed. A minute later, your position appears stable; and that's the point of time where real positioning data are used - not just coarse estimations.
It all depends on that almanach data and a clear view of the sky.
