Devices Tycoon Mobile OS Editor: Design & Test Guide

What Does the Devices Tycoon Mobile OS Editor Do?

Build a phone interface you can actually explore with the Devices Tycoon mobile os editor. Your choices shape everything from unlocking the screen to switching apps, giving your company’s software an identity beyond its logo. The Devices Tycoon mobile os editor lets you customize that experience and interact with working features inside the game.

On the Steam PC version, “mobile OS” means the operating system you design for smartphones within your company. This guide covers that editor, including its interface controls, built-in apps, testing opportunities, and relevant fixes through Update 1.3.

You can shape the system around an iOS-inspired layout, an Android-inspired layout, a combination, or your own visual direction. Customization reaches beyond wallpapers and icons: navigation, notification placement, keyboard feedback, app interfaces, and animations all receive attention.

The broader OS creation process starts with choosing a name and logo. Employees then develop the base version, after which you can add design elements and technologies. Regular OS updates can attract company fans and bring in additional revenue.

Choose a clear visual direction before adjusting individual screens. Carry that direction through the launcher, system controls, and apps so your operating system feels connected as you move through it.

Shape the Home Screen, Lock Screen, and System Controls

The Devices Tycoon mobile os editor gives you control over the screens you repeatedly encounter while using your simulated phone. Start with these shared elements before spending time on individual apps.

Interface area	Customization options
Boot and sign-in	Progress bar, animated splash screen, password buttons, backgrounds, and colors
Home screen and app menu	Icon placement, bottom app dock styling, and system navigation
Icons and folders	Backgrounds, opened-folder appearance, search styles, and opening animations
Lock screen	Widgets, notifications, sliders, unlock methods, and locking animations
Notifications	Placement, shapes, colors, and styles for locked and unlocked screens
System dialogs	Confirmation, warning, and loading windows, including buttons and animations
Volume panel and control center	Panel placement, volume animations, button states, and control center backgrounds

Give everyday screens a consistent identity

Set your home screen arrangement and navigation style before refining smaller details. Those choices establish how you move between the system’s other screens.

Match folder backgrounds and icon treatments to that arrangement. For example, use a shared color palette across the dock, folder windows, and notification panels. This is a design choice you can apply throughout the editor, rather than a required preset.

Pay attention to the difference between the boot screen and lock screen. Boot customization covers the startup presentation and sign-in appearance. Lock screen customization covers widgets, notifications, and how the interface looks while locking or unlocking.

Make system states easy to recognize

Give active and inactive control center buttons visibly different treatments. Customize notification shapes and backgrounds so their text remains readable against your chosen screen design.

Use warning and confirmation windows deliberately. Their separate customization pages let you give each type a recognizable appearance while maintaining consistent buttons and colors.

Animations deserve the same attention. The editor includes feedback for pressing icons, opening folders, entering apps, changing volume, and locking the device. Reuse a visual style across these interactions to make transitions feel connected.

Icon changes appear in real time while editing. Compare them against the surrounding interface as you work, especially when changing backgrounds or outlines.

Customize the Built-In Apps and Keyboard

The Devices Tycoon mobile os editor extends your design into the apps themselves. You can maintain a shared appearance across the system or give individual apps their own personality.

App or component	What you can customize
Calendar and Calculator	App designs using their customization tools
Clock	Overall appearance plus separate timer, stopwatch, alarm, and world clock sections
Notes and Keyboard	Text styling, selection effects, key appearance, outlines, emoji, and animations
Gallery and Email	Media viewer layout and styling, email windows, and message composition screens
Camera	Main and front camera interfaces, photo and video modes, filters, and styles
File manager	Element placement, outlines, colors, and folder and file styling
Music player and Settings	Player interface elements and the Settings app’s appearance
Wallet and Antivirus	Card appearance, payment result animations, and antivirus interface design
Calls and SMS	Call categories, call interface animations, chat appearance, and messaging controls

Carry your design into text and communication

Notes lets you adjust text appearance, selection, and deletion animations. The virtual keyboard goes further, with individual key customization alongside keyboard backgrounds, key outlines, press effects, and emoji.

Design these components together. Open Notes and enter text to inspect how your keyboard looks beside the document interface. Check the distinction between selected text and the surrounding content.

Calls includes recent calls, contacts, and dialing, each with its own appearance options. SMS lets you customize conversations and write messages. Keep frequently used elements recognizable as you move between those screens.

Email includes separate windows, such as the message composition screen. Files can be attached through Gallery, connecting the two apps within the simulated system.

Refine media and utility screens

Gallery offers control over element placement, styles, outlines, and animations. Camera includes customization for both main and front cameras, along with photo and video modes.

Coordinate their visual details so moving between camera controls and the media viewer feels coherent. Apply the same thinking to file and folder icons in the file manager.

Clock deserves a separate review because its sections can be styled independently. Check the timer, stopwatch, alarm, and world clocks individually after changing the overall app appearance.

Wallet includes card designs and separate animations for successful and failed payments. Give those outcomes distinct visual treatments. These are elements of your in-game OS interface.

The Antivirus app also has its own appearance editor. Carry your system’s button styles and palette into it rather than treating it as an isolated design.

Test Your Design Through Real Interactions

The Devices Tycoon mobile os editor includes working interactions you can use to inspect your design. Settings changes connect with other apps, the music player plays music, and the app switcher lets you move among minimized applications.

Use those connections to review complete interactions. A screen can look appealing on its own while its buttons, animations, or surrounding panels clash with the rest of your OS.

Interaction to test	What to inspect
Boot and sign-in	Startup presentation, password controls, and background colors
Open an app and return home	Opening effects, navigation, and home screen consistency
Open the app switcher	App presentation and switching animations
Play music and adjust volume in Settings	Player appearance and the linked volume change
Write in Notes or SMS	Keyboard styling, text readability, and press feedback
Compose an email and attach a Gallery file	Appearance across the composition and media selection screens

Follow a repeatable design pass

Use this sequence as a design checklist:

1. Set the core layout. Choose the home screen arrangement, dock appearance, and navigation direction.
2. Style shared components. Adjust icons, folders, notifications, dialogs, and system panels.
3. Customize built-in apps. Apply your chosen colors and control styles across their screens.
4. Inspect connected interactions. Move between apps, use the keyboard, and change music volume through Settings.
5. Review animations. Check transitions and press effects alongside the interfaces they belong to.
6. Save and reopen your work. Review the appearance again after loading.

This order organizes your editing session; individual controls remain part of their respective customization areas.

Balance appearance with performance

The OS design system includes a tradeoff between visual complexity and resource use. More elaborate styles and animations demand more system resources.

Compare animation choices while watching the OS performance information. Reduce visual complexity when you want a lighter design, and add effects selectively where you want stronger feedback.

Keep your changes focused during each pass. Adjust the keyboard’s appearance, inspect it in use, and then move to another component. That makes it easier to judge how each design choice fits the surrounding screens.

The Devices Tycoon mobile os editor also gives you useful cross-app checks. Change volume in Settings while using the music player, or inspect the keyboard in both Notes and SMS. These interactions let you review shared design elements in different contexts.

Use Sandbox Features and Keep OS Fixes in Mind

Sandbox Mode gives you room to experiment with your company and designs. It became available from the start in Update 1.1, while the first post-launch update added unlimited money in Sandbox Mode.

Update 1.2 added an “Employees Are Always Happy” toggle and a “Research All” button within each research category. Use those Sandbox controls when you want to spend more of your session exploring customization.

Several updates also addressed OS design persistence and related display issues.

Update	Relevant change
Update 1.1	Fixed OS designs resetting after restarting the game
Update 1.2	Fixed untranslated Russian text in “My OS” licensing and “NaN%” in Private OS statistics when user count was zero
Update 1.3	Fixed custom OS design settings unexpectedly resetting

If you previously lost appearance settings in the Devices Tycoon mobile os editor, install Update 1.3 before rebuilding the design. That update addresses another reset issue beyond the restart-related fix in Update 1.1.

The first post-launch update also introduced autosaving every 90 in-game days. Save after a substantial editing session, then reopen your OS to check the result.

Keep your attention on the interactions you want to refine next: a clearer control center, a coordinated keyboard, or a more consistent set of built-in apps. The editor gives you enough individual controls to work through those goals one component at a time.
