There are following points need to take care while mobile design:
Reach Area
Thumb Reaching Zone: How easy to reach our thumbs to tap areas on a mobile phone's screen.
Hard to reach
Reaching this area requires uncomfortable finger movements and a lot of stretching
Okay to reach
Reaching this area requires some stretching. Can be hard for users with small hands
Easy to read
Reaching this area is very easy on nature and does not require stretching.
Platform Guidelines
We have to use the right design system for iOS and Android. Both iOS and Android have a different user base. Also never carry UI Elements from e platform another.
Apple's Human Interface Guidelines
We are already aware of the In-depth information and UI resources to designing pixel-perfect applications to integrate seamlessly with the Apple platform
Guidelines Material Design
Material design is an adaptable system of guidelines, components, and tools that support the best practices of user interface designs for android.
Think device first
First, we have to be aware of the “unsafe areas” (notch, camera punch-hole, etc.)
Unsafe Area
Be careful when designing in these areas, you should not include menu or tab elements in there.
Safe Area
Everything within the “safe areas” will be visible on different device screens.
Font Type and Font Size
Every font can evoke different emotions and provide easy readability at the same time.
Typeface
We have to choose a typeface that works well in multiple sizes and weights to maintain readability and usability in every size
Font-Size
Use legible font size. The text should be at least 11 points so a user can read it at a typical viewing distance without zooming
Contrast
Use contrast checkers to prevent color problems, also use 60-30-10 rule which refers to an ideal proportion that is meant to reach a balance among colors
Call to Action (Buttons)
We have to design finger-friendly buttons because Mistaken taps often happen due to small touch controls
Create controls that measure a minimum of 10-12mm (40px) in order that they are often accurately tapped with a finger.
