Informed that delivery would be 3-4 weeks after I ordered. Tried calling to cancel but unable to get through (queue always 15-20 long); waited 45 mins but couldn't wait any longer. Phone arrived after 2 weeks. A week later, phone suddenly shut down during use and wouldn't restart until put on charger. Been ok since but not a good start.
