My V20 works flawlessly. However, I just noticed the other day that the phone is not perfectly flat, but rather appears to be twisted. If I set it on a table (which is known to be flat and true) it will rock slightly from the NW corner to the SE corner. The same thing happens if flipped onto its screen side. It rocks corner to corner. This indicates that my V20 must not be flat. It is twisted a bit. Anyone else notice this?
