I recently made a couple of hard resets on my Samsung Galaxy S4 Mini.After the last one, on the screen for writing my SIM pin code, when I started to type, the screen freezed and after a couple of seconds the following appeared: "Process system isn't responding.Do you want to close it?".I chose "OK" instead of "Wait" and everything went fine afterwards.In curiosity, I made a couple of more hard resets but the problem didn't appear again.Any idea what the problem might be?My smartphone is new (1 month old), but I have made many hard resets to it.Have the system started to fail because of these hard resets or this is just a random error and there is nothing to worry about?Thank you.
