First few seconds for unlocking the phone

[Wastelands]

HI! My phone doesn't react to drawing unlock symbol. I have to wait 2-3 seconds when LED will blink and then I can unlock phone. Is it bug?

Try booting into Recovery Mode and wiping the cache partition, which won't erase any personal data: http://forums.androidcentral.com/sa...ing-into-recovery-mode-galaxy-s2-s3-tab2.html
