GPS not working - everything else is fine

WiFi and Cellular work fine. GPS does not work. Location services are on. I have recently upgraded to iOS5 and replaced the mid frame assembly... Connector 6 is secure and not broken.

Could it be because this part is not inside the phone? :)

I don't know where it came from and can't find out what it's supposed to do from any of the photos on this site...

Answered! View the answer I have this problem too

Is this a good question?

Hello,

The part is from the camera. It sits above it to secure it down. The teardown guide will show you exactly how to put it in.

What I would check:

1) Make sure you are getting a strong wifi connection. Sometimes you will get a strong reception very close to the source, but as you walk a few feet out it will drop to no reception. If so, let use know.

2) If still strong, I'd do a simple check for all connections on the board.

Hope this helps,

WiFi works very well. Even at extended distances. The connector for the GPS snaps in in a very promising and strong fashion. Maybe I damaged the antenna somehow?

Hello,

Only two possible solutions I can think of:

1) Check inside the iPhone, near the bottom right of the board, there is two metal "wings" that stick up and touch the metal frame. Are these intact? Are these touching the frame? Be careful if you have to adjust these wings that you do not snap them off.

2) Did you happen to have this unit unlocked? In my experience, I have never seen the GPS not work, when WIFI does. Do push notifications work on the phone? This is likely, if not surely, a software based problem. I would do a complete restore, and setting up the phone as a new device.

Hope this helps,

I think the little prongs you're talking about are for wifi/cell - the GPS antenna is a all by itself at the top of the phone. I asked the same questions over at the apple forms and it turns out a lot of other folks have the same issue.

Yes. I didn't upgrade. I always start clean. I have also wiped and reloaded and reset on several occasions.

Hello, lately I was disassembling my iPhone 3GS (only motherboard was disassambled) after reassembly everything works but GPS. Wi-Fi signal is really strong - just fine. Same with Bluetooth.

My 6 connector is sitting well. When I unplug it, Wi-Fi and Bluetooth signal are very poor.

Small pins in bottom right corner of the phone also seem to contact well.

There is some GPS signal (not Wi-fi or cellular assists, but acutal GPS signal) but it is really poor comparing to my brother's iPhone. Too week to use turn-by-turn navigation, which was always working extremely well.

I even bought a new GPS/Wi-fi antenna and I connected it without mounting and it seems to behave exactly the same, so I doubt it's because antenna - I tried to be very gentle to not broke anything while disassebling motherboard.

Have you guys any ideas? I really need GPS in my iPhone since it is my only navigation system.

Please forgive my bad english.
