Galaxy note 2 - N7105 GPS not working - No satellites detected

Hello,

I've noticed that my GPS was taking too long to fix my position on GPS App.

I used high precision (GPS+Wifi+3/4G).

I've installed from market GPS Test App to see if it catches satellites and confirmed that the Phone is not able so detect and connect to any satellite.

I'm using a custom FW stock based with simply don't have the operator App's and trash.

The GPS allays worked well.

Maybe 8 month's ago i had accidentally dropped water from a glass into phone and it was cleaned on that moment.

The phone continued working well with no issued.

2 weeks ago, before this GPS issue, the phone fall out from my pocket to the ground form a high of just 10cm with is nothing.

I have disassembled all the phone.

No Hardware problems detected on the motherboard and cables.

No dirty inside.

No sight of water inside.

The board and contacts are clean and shine.

I have re-assembled the phone again but the GPS still continues not seeing satellites.

I have rolled back to an oldest stock FW and upgrade it via android, with no effect.

All the phone works perfectly, except the GPS!

When turning GPS On there's no error/alert.

I didn't detect the GPS antenna with i think it is between the lCD and the front chassis both are glued and i was not able to access it.

What else can i do in order to solve this GPS problem ?
