[General Questions and Answers] Felix.lutaya:
I stay in africa(uganda) I sold my nokia n900 to buy a used unlocked tmobile samsung S 4G vibrant which has become my worst nightmare...the phone drops network signal and sometimes when I pull it outta my pocket it will show (searching) but will connect after 30minutes else i have to reconnect it my self in network setup..all that was not a problem to me because I work in the capital were network is always up in 5bars both 3G&2G but loses it quickly in some building..

Problem:

When I leave the capital just 15 minutes away it starts to drop signal from 5-0 but will regain in some places...it does this in areas that other people on the same network as me won't get a problem so do my previous 3G phones including the previous n900 I owned.

Things get bad when I reach home in that I barely get a bar in 3G and only 5-4-3bars in 2G it keeps on playing and in that process it will go to (searching) until I reconnect manually which forced me to look for a solution on the internet.

Solution I got:

Connect magnet wire in the back external antenna input at the back of the phone, guess you all have seen that hole, in the video the guy got 3bars from 0-1 bar which convieced me that my network problem is now solved.

Starting the trick:

I cut my tv antenna wire in two pieces, removed three thin silver wires and tested one by one.

The first two failed but the third one brought the network down from 0bars of 3G upto 3bars 3G.

Going on with the test now very happy I try a more fitting object I inserted the niddle which I used to remove the rubber cover which covered the external antenna input.

My nightmare begins:

Immediately after I removed the niddle, the signal bars all went off to X but mine shows a circle and a line touching both sides.

When I reinserted the niddle I got the signal back but this time only 2bars for 2G which was 4-5 bars before and 0bars for 3G which could dare 1bar.

finally:

Now I just removed the niddle, network went off again now my phone was relying on the niddle maybe the internal antenna was now disabled or ruined by me.

I hard reseted the phone, cleared cache but all didn't work..i put back the niddle in the hole It all came back.

Yesterday I took it to a local repair shop and today when I picked it I had -79dbm 2G and -53dbm 3G but when I left the shop 15 minutes away I got an X then 5-2-3 bars of both 3G and 2G..thaugh i got the network back without niddle support. The network is badder than how it was when I first bought the phone.

What the repair guy did:

He rolled a copper wire around the external antenna input and soldered it to an object just near th ext antenna input.

Finally:

What could have been the problem in the first place?

How can I solve the problem?

my last say: I have tested 3 different 3G phones with my simcard and all have performed well in my house with full bars and I don't remember having network issues with my previous 3G nokia phones, my brother who has a galaxy pocket doesn't face network problems either..i have tried all network operators with no success but still the same problem and now come for your help because after the niddle night, alk has become was! I like the phone soo,much cause its my first android but am afraid I can't have it like this, friends call me and it has already disconnected from the network even when the bars are still there in full swing..........
