You can bet that if that bug was in that, it could be in other products.
I have a 3 year old Samsung SCH A970 Cell Phone.
I love it.
Recently the original battery hadn't been lasting as long as I'd like.
Thinking it was time for a new Battery, I bought the Samsung Brand "Extra Capacity" style.
I charged it up and put it in my phone.
All was fine for the 1st 8 hours or so.
Then that night, I went to check the Battery Condition.
When I opened the phone, the Keyboard was lit up but the screen wasn't. It was just Black.
I tried to turn the Phone off, but it wouldn't let me.
So I had to remove the Extra Capacity Battery which allowed the phone to turn off. I put the OEM Standard Capacity Battery back in and the Screen lit back up and everything was fine.
It did feel as though the Battery and Phone were a little "Warmer" than usual, but I don't know if this would be due to the Extra Capacity Battery.
Does anyone have an idea as to whats going on?
