The failure is the rechargible battery. The battery will not charge, it is defective.
The phone itself is really eye catching. The pro mode is really cool and you can do long exposures, night photography. It's an eye catching phone packed with features and hardware.
With the z fold 4, it is quite noticeable.
Once you fold out the phone, it really grabs peoples attention. It's much skinnier/chunkier than the iphone and heavier as well. In your pocket it feels like you have a brick in your pants.
