There are some questions that you need to ask your graphic designer. These are as follows:
1. Do not go overboard
If you are a beginner, avoid going on in terms of creativity. Although creativity and innovation are good but try to keep it simple and error-free. So, creativity must be within the limits of easy detection of errors, if any. You can check this link if you are looking for a graphic design agency.

2. How much involvement will you have?
This is often largely based upon cost and billing structure; if you are working on hourly billing then your designer will be keen to talk with you as much as you like, but projects moving forward from a single quote will be subject to more stringent time management for obvious reasons.
By asking these simple questions, you should be well on the way to finding a graphic designer that can provide exactly the kind of service that you require.
3. Experience as a user uses your primary motivation
As the main focus of an Android application developer is to serve the needs of users and develop the application according to the client's requirement. Creating an application with a user-friendly interface and make the interface a pleasant experience should be a major concern of each developer. This application must be easy to operate, bug-free.
