Hey everyone,

A while ago I bought a Samsung S8000 jet and it had to suffer some minor water damage. Samsung and their repair centers did not offer any warranty (which doesn't surprise me) but they also refuse to repair the phone outside the warranty.

Now, there, warranty void anyways I decided to open up the phone myself. There is hardly any visible water damage inside the phone. The chipsets were all intact, the phone works just fine, there's just one 'small problem'. I do not get any reception.

After some more looking about I discovered that there are 3 'batteries', namely the main accu. 3.7 volt which you can remove from the back of the phone, a back-up battery on the main print itself (6.4 volt which, among other things, will ensure the time and date are not reset every time you remove the main battery) and another battery attached to the main print but not directly a part of it. This last battery was corroded and is dead.

The problem with the reception is as follows. At very specific places I get a perfect reception, but at other places I never have any reception. And most of the time I get no reception at all.

Now, there is this thing about passive and active antennea; an active antennea being powered thus receiving more signal, and a passive antennea just being a chunk of metal (I know it is not really that black & white but ok...) that receives signal. Could it be, that because of this dead battery the antennea now is a passive antennea instead of an active one (which explains the reception problems...)? Or is my theory full of flaws? I know that it is rather unusual to have the antennea powered by a battery other than the main accu, but considering that the Samsung Jet has a powerful 800mhz processor, I believe it might be very logical that they chose for this construction as a more powerful processor requires more power to function properly, and they did not want to make any concessions to their universal Samsung Charging devices. (Which gives a solid ~4 volt output) so they had to choose for this 'triple battery system' to fully satisfy the power needs of the phone.

So summarized my questions are;

1) Is this theory viable? Does it make sense or can anyone argue/prove it is totally wrong?

2) Does anyone know what battery (type, voltage etc) is used to 'power' this antennea?

Any advice is absolutely welcome! Thanks in anticipation!
