This is as expected as contents have not been created/adapted to it. Additionally, it is more of the fault of the Android and developers, and less on the aspect ratio itself.
The fingerprint sensor’s location might not be to one’s liking. Yes, your finger naturally rests at the proximity of the sensor when the device is in using it. However, I still find myself missing the sensor being at the front. This can be due to how convenient it is to unlock the device on the go, as your thumb are instinctively placed on the sensor while pulling it out of the pocket. Additionally, it is also much easier to unlock the device when it is placed on the dock/table, with no need to pick up the phone.
