Have the smartphone received after about 3 weeks. First impression was really great. Sorry, no stable wireless connection can be established. In addition, the headphone jack and the supplied headphones had a loose connection. Then I wanted to return the phone and reported to the seller. The wanted me to send him a video that documents the malfunction. How does that work? After repeated correspondence in unintelligible German smartphone then could be sent back. Meanwhile, the money was refunded.
