MIUI 2.1.6 Charging bugs


Jan 14, 2012
hi.i have a samsung galaxy s (GT-I9000).yesterday i installed new miui 2.1.6.it is perfect but when you connect it to charger it has some kind of bug (touchscreen doesnt work well).i was playing game when i realized it and i tought it may be a hardware problem . but when i disconnected my phone from charger it was working well(it also works well when you charge it with usb cable).
i don't know if the problem is mine or miui's.....
