Phone Number Issues

[dmytronasyrov]

1. TextField underline should be lower. Letters and cursor are too close to it.
2. TextField tint color should be white.
3. Country picker and phone keyboard should have the same colors.
4. Make nicer look for the phone number. Ex: +380 99 776 27 91
5. All colors are different from design layouts - background, underline, secondary text.
6. Button size is different from layouts.
7. Popup doesn't match our design (popup design example below).
8. User should be able to enter a new number from the scratch, not starting from country code. Country should change if I will enter +380.
