Please don't worry, we will help to solve it.
Please create a repair ticket ID first.（That's important, We judge the warranty period based on this time.）
If it's under warranty, we will give you a second DOA repair, and we will apply coupons for you for the round-trip freight and free repairs.
Please ship back them within 15 days from Repair Ship out date, otherwise the devices cannot be treated as a second DOA repair.
