PSA: remove bottom screen protector if you have one and your console is unresponsive

So I bought N3DS which had a protector film applied. There were a couple of dust specs under the film. It worked fine for a while but then it started to act up. It became unresponsive. Nothing except ZL, ZR, C-stick and power button worked. Resetting sometime helped but less and less often. After some research I found out that this can be caused by faulty touch screen. Before digging further I removed the protector. That fixed it. That’s all folks.
