Samsung Galaxy S 3 problem!!

ISTARI SG

I recently bought a s3. Now it’s giving me problems. Suddenly when I use, it will emit thissthis strange sound ” tleeng”. I’ve checked everything. Nothing seems to be the problem. Even did a reset to the system according to factory setting. Anyone know what’s happening?

if it's still under warranty then just bring it down to the customer svc ctr at PS or JP for a check..

Ok. I just realised the cause. The phone actually interferes with credit cards and ez link. Apparently there some disturbances that the chip inside can cause. I use the phone cover which has compartments. Once i remove the cards, everything went normal
