I use a Samsung SGH-x427, and sometimes when it's around other electronics it will make them make a rhythmic 'dun tchk dun tchk dun' (best I could describe it in typing) noise (happens with speakers) and if it's by my monitor, it makes the monitor go all jumpy and screwy. Also, if that occurs and I open it, the screen will be black and the keypad doesn't light up (as if it's frozen) and won't come up for a long while (sometimes happens anyway).
Is my battery messed up, or is it my phone? Help?
