content：Tired of Boring Call Screens? Here’s Your Solution

Tired of seeing the same plain call screen every time someone calls? You’re not alone. Most default call interfaces lack personality, but there’s a simple way to fix this—using the Color Theme app, as demonstrated in the Technical Expert Baba YouTube channel. In this guide, we’ll walk you through exactly how to customize your call screen with live wallpapers, personal photos, or unique themes to make every incoming call feel special.

content：Why Customize Your Call Screen?

Customizing your call screen isn’t just about aesthetics. A 2022 Statista report found that 68% of mobile users customize their device interfaces to reflect their style and improve usability. Unique call screens also help you quickly identify callers (if you set specific themes for contacts) and make your phone feel more personal. The Color Theme app simplifies this process, offering a range of options for every preference.

Step 1: Download the Color Theme App

First, download the Color Theme app from the link provided in the video description. It’s free to use, with optional premium features for advanced themes.

Step 2: Grant Necessary Permissions

Once installed, open the app and grant it access to your calls and storage. These permissions are essential for the app to modify your call screen and access your photos/live wallpapers.

Step 3: Choose Your Preferred Theme

The app offers three main options:

Static Wallpapers: Pick from a library of pre-made designs.
Live Wallpapers: Select animated backgrounds that move when a call comes in.
Personal Photos: Upload your own photos or videos to use as the call screen.

Step 4: Set the Theme

After choosing your theme, tap “Set for All” to apply it to all incoming calls. For specific contacts, select “Set for Specific Contact” and choose the person you want to customize.

Step 5: Test the Theme

Make a test call (ask a friend or use a free call service) to verify the changes. You’ll see your new call screen in action, complete with the theme you selected.

Free vs. Premium: To use premium themes without paying, watch a short ad instead. This is a great way to access advanced designs for free.
Built-in Options: Some Android phones (like Samsung with One UI) have built-in call screen customization. Check your phone’s settings before downloading third-party apps.
Permission Safety: Always review app permissions. The Color Theme app only needs call and storage access—avoid apps that ask for unnecessary permissions like location or messages.
