The Galaxy Z Flip 4 is a wonderful phone for its pricing. The build quality, firepower, cameras, and software update scenario are all top-notch.
Galaxy Z Flip 4’s cover display features new tricks. Fresh clock types, the option to use video files as a cover screen background, more straightforward notification interactions, additional widgets, and clever utility features increase the cover screen.
It’s limiting, though. The 1.9-inch screen doesn’t allow Samsung much area to showcase its software, but it’s not impossible. CoverScreen OS is an app-based launcher for the cover screen.
CoverScreen OS was created by XDA-recognized developer Jagan2. You may launch any app, browse them with an app drawer, add widgets, and more. It works amazingly well.

Galaxy Z Flip 4 CoverScreen OS
The CoverScreen OS programme requires a number of permissions before you can begin setup. Step-by-step instructions and buttons direct you to the system access page.
CoverScreen OS uses swipes. Once you get used to it, remembering them is satisfying. CoverScreen OS navigation gestures employ the other three sides because right-edge gestures are limited to One UI.
You also get app- and feature-specific gestures for simple tasks. Pulling up from the bottom border displays media playback. Swiping in from the right half of the screen opens app widgets and down opens quick toggles.
A right-edge swipe brings up the notifications shade, which is more detailed than One UI’s default tray. What you can do with these simple gestures is exciting.
Cover screen upgrade
Tapping anywhere on the screen opens the app drawer and adds four buttons on the right: changing orientation, search, alphabetical sort, and most recently used apps. Long-pressing opens clock face modification. Swiping left on the cover screen launches the previous app, and swiping up opens the app drawer.
In settings, you may control how apps behave on the cover screen. You can allow or restrict notification contents unless the phone is unlocked, move app action to the inner foldable screen, or alter edge lighting for notifications.
App widgets follow. Almost every preloaded and third-party app, including Asana, Google Drive, etc., has a widget. Before adding widgets to apps, check sure you’re signed in.
On the little cover display, I set up my Twitter account. I loved being able to type on the cover screen. Type or dictate a text. This isn’t true.
You can pick between a T9 keyboard and a QWERTY keyboard for keyboard input. Space limits mean no swipe typing, suggestion row, or emojis. It’s still there and saved me dozens of folding-unfolding cycles daily.
Some features, including hiding apps from the app drawer, cost money. Even the four app-icon navigation buttons require a membership or purchase. $2 per month or $15 annually.
This isn’t ideal.
CoverScreen OS boosts the Z Flip 4’s cover screen, but it’s not ideal. Depending on your expectations, a few annoyances might make or break the trip. In the app drawer, you can’t pull down to get fast settings. Swipe up to see media playback.
A bittersweet annoyance follows. When your phone locks, biometrics lock apps. This could protect Phones, Photos, and Mail.
Notifications from WhatsApp, Slack, Teams, and Telegram can be unpleasant. I even hit biometric unlock on the calculator. Cover screen convenience?
Unreliable swiping gestures. When I entered Settings, neither the back swipe nor the home swipe functioned. To return to the home screen, I had to lock and unlock the phone.
CoverScreen OS’ back gesture doesn’t work well with swipe-heavy apps like Discord. New Quick Settings toggles require a one-time purchase or subscription. Did I mention that the Settings page always has ads? Likewise!
Even brightness and sound are paywall-locked. Notifications have similar limits. To access the whole email notification cover screen, you must pay.
Foldable phones helped me curb my bad smartphone habits. Notifications on an ordinary phone distract me. Twitter and Instagram notifications usually lead to doom-scrolling.
When I receive the identical notification on the Galaxy Z Flip 4‘s cover display, I don’t bother accessing the distracting social networking apps. Even for office apps like Slack and Teams, I can reply without opening the inner foldable screen unless necessary.
CoverScreen OS ports practically the whole smartphone experience to the secondary screen. Despite its benefits, it will be more distracting than a glance screen.
CoverScreen OS makes the cover screen more useful than Samsung’s One UI. Things have improved, but there’s also more room.
Porting the app drawer to the cover display is understandably difficult. Not all apps are enjoyable. Tweets require squinting.
Instagram and Snapchat won’t work on the Galaxy Z Flip 4‘s cover display. Increasing a YouTube video’s resolution causes stuttering. With CoverScreen OS, you can do nearly anything on the cover screen.
Samsung can improve an app’s UI for the secondary screen, but not alone. Plus, convincing developers to modify apps for the Galaxy Z Flip 4‘s cover screen is tough.
I appreciate being able to react to WhatsApp messages without picking up my Galaxy Z Flip 4, but I don’t want to pay for an app. It’d be cool to ask Google Assistant to organise a Google Meet call or Bixby to turn off the living room light. If Samsung is willing, a card-based interface will do.
CoverScreen OS lacks professional apps and an intuitive UI. If you hate paying for apps, go clear. CoverScreen OS is a brilliant concept, and its developer deserves praise for doing what Samsung couldn’t.
