I just bought the Samsung Galaxy Note spare battery charging system and it came with an extra battery which is just the stock 2500mAh. When I put this new battery in my phone, it started acting strange. Every once in a while when I open an app the screen goes all black and the phone doesn't respond in anyway for about minute, then I hit the button on the side of the phone and the lock screen comes up and everything is fine again. The battery has all the same numbers on it as my original except for the serial number. Any idea why it would do this?
