S3 Charging issue - Help needed

[alifkaf]

Samsung Galaxy S3, bought - June 2012

I was facing charging problem with main socket as well as with USB cable.. I zeroed in to the fact that my s3 charging pins are faulty after trying all possible combination of different battery, charger, USB cable, phone etc. I have also done factory reset but it didn't solve the issue. I even bought a battery and separate charger to confirm my findings and they did.
I called up Samsung repair center(3 June) as my phone was still in warranty, they lodged the complaint and will be sending somebody to collect the phone tomorrow(10 June).
I wasn't using my phone for the last 3-4 days, last night I just thought to give my phone charging a try and hey it started charging perfectly fine. I tried the USB cable and it is all good. I charged it again in the morning today and all set. No issues.

And I am all confused now. My dilemma -
1 - Now that my original issue looks to be resolved, should I still send my phone to Samsung repair center (which means that I will be without my phone for next 3-4 weeks, I cant expect Samsung to be more quicker than this)
2- if it is working fine, what Samsung will do with that phone?
3- Is it okay to send a working phone to repair center?
4- has my charging problem been just temporarily resolved?

Please suggest at the earliest as I have time till today only to decide whether to send this phone to Samsung or not.

Many Thanks en avance

catch 22. i see more and more of charging issues. i think the hungry phones and cheap manufacturing are to blame. if its the main socket you need them better now than later. simple cable is main link in circuit. i would return it all an let it be checked. an interment issue would present its self as a working phone sometimes. good luck
