Some suggestions as discussed.
Regarding display of amounts: I would use a mono-spaced font and align them all to the right, so the decimal separator is always in the same place.
I wouldn’t display the Slatepack Address in green, but in white and add some copy icon to the label. Green creates some false sense of accomplishment for me.
“Backup Wallet” and “Close” on the TX details screen could be real full-width buttons below each other. I would not use red (“danger”, “delete”, …) and yellow (“warning”) for them, but display them as secondary options in black and white/gray.
Connected peers could be a zebra-striped table with leading counting numbers, in order to improve readability.
Paste from clipboard looks empty. The icon could be huge and centered above the label instead. Maybe some gray rectangle behind that, to make more clear that the area can be tapped.
In some places labels are gray and values are white, but not always. It would be good to keep that consistent IMO. Labels could be always gray.
In the TX list, received and canceled TXs look pretty similar. Maybe icons or some color coding would help.
Since I cannot test it right now and I see no pending TXs in the screen, I wonder how those would look like and how the calls to action on them would look like.
I will try to invest more thoughts later.
