Well, I'm on my second device from the first week after the exchange. I traded since I met the problem that 70% of the owner of this plate will lock the device and requires unplugging completely. I thought the second working but it is not the same problem. So Peekton really sells batches of defective products and the only way to solve the problem and to change a component in their service that lasts 3 weeks. In short a shame to sell products knowing where will the fault systematically.
