Defective functions... Yes Please read the profile before purchasing. Please understand and purchase. I bought this used to watch YouTube, but I am selling it because I bought another iPad. When the screen is white, a red discoloration can be seen. I didn't mind it when I was watching YouTube. Also, even when the battery is charged, it only charges up to 87%. Even after leaving it for two days, the battery didn't run out, and I used it by charging it when it was low while watching YouTube. The battery is also considered junk. The main unit Bonus: Brand new, unused Logicool keyboard cover will be sold. Please consider it as junk. Storage capacity: 32GB
