Do you have any custom rom installed? I had exactly the same issue on my Samsung Galaxy S2 with SentinelROM. That problem dissapeared after flashing AOSP NeatROM on my phone. You could also try unrooting your phone, again reset factory settings and test it. If it's working fine, you could try rooting your phone again.
