Hi, I am not sure if this is a known problem, or maybe it just happens on mine. The physical keyboard sometimes would not work properly, and the same keys would not respond at all when it happens. from time to time, the "e", "y", "g", "i", ".", among other keys, would not work. it is really annoying... when this happens, i'll switch to the virtual keyboard and finish whatever i am typing... i switch back to the physical keyboard, and the problem would still be there. When I turn the phone complete off, then turn it back on, the problem will go away... then it will happen again at some point... i am not sure if it is a hardware or software issue. maybe there's an app affecting it? i highly doubt it though... i paid retail for this phone, and i still have time to return it if i have to... i just want to know if it can be fixed by maybe factory resetting the phone, or if i should just return it. i love the phone, and will get another one if returned... thanks for any suggestions!
