  • DND mode
  • Flex Mode - use cover screen while phone is unfolded
  • Caffeinate - keep screen awake
  • Power Dialog on cover screen

  • More colors, customizations under development.

  • Keep the phone on your desk or bed in tent-style stand mode.
  • Cover screen stays on until you manually disable Flex Mode or fold back your phone.


DEVELOPMENT STATUS:


The OS requires some heavy sustained development effort to deliver a feature complete version. The OS has come a long way and it’s mostly stable now as reported by majority of the users on Z Flip 3.

THE ORIGIN STORY:

Been working on this project since the original Z Flip, but unfortunately had to suspend development due to cracked screen (that countless folding/unfolding while testing.)
Z Flip 3 crack 1.jpeg


The release of Z Flip 3 with a bigger cover screen was enough incentive for me to be excited about the project once again but unfortunately I again hit a bottleneck as the screen started bleeding this streak of green light right at the center and sometimes whole of second half.

Fearing a cracked screen once again, I had suspended the development yet again… but… that cute little cover screen… here we are. :)

I used it on my flip 4 but ran into an issue with an app I use for work (3CX) it shuts the vibrating notification off after 1st vibrate and it goes silent. Had to uninstall in the meantime. Other than that I loved all the options and being able to open apps without having to open the phone.

Hi there! I am glad you like the features.

Regarding your specific use case, I am not sure if I can try the App (3CX,) does it allow a public account? Did you enable the VoIP Caller ID for 3CX by turning on 'Universal Caller ID'? If so, that would be the likely cause of it, as supporting Caller ID for unknown Apps is 'experimental' at the moment. If you disable it, you should have no problem with your specific use case, let me know how it goes! :)

I did disable it, I had it enabled only for the supported apps on my side but it continued to misbehave on me. I'll try a couple things later tonight and let you know

-------
UPDATE: Did a reinstall, restarted the phone and 3CX is behaving correctly now.

I remember when all the coverscreen launchers originally started you had to delete the Samsung Health app to install, is this still the case???? It would be awful nice to know before reading any further or bothering with the download and installation as I refuse to delete Samsung Health. Do you have to delete the Samsung Health app to install? Yes or No?

No, you don't need to uninstall Samsung Health.

Hi !
I've installed CSOS on my Z Flip 4 and I can't manage to use widgets...
I swipe from right to left as explained in the tutorial but it keeps showing samsung widgets.
EDIT : This issue is resolved in the latest version (100+)

The text written with keyboard (or voice dictation) does not appear in text field in gmail app.
But for the subject field, it is OK.

For SMS, with native samsung app, when text is written, the keyboard disappear so SMS can be sent -> OK
With google message app, as long as cursor is in the text field, the keyboard keeps appearing, even if text as been written and confirmed, the keyboard appears again and again... Text cannot be sent.

Otherwise, super great app, makes the z flip 4 a lot better !
I wish i can get the full version with unlock features but the high price and bugs stops me...

Hi! This is the original and first implementation, that discovered a clean way to display over cover screen of Z Flip phones. CoverScreen OS never required any dirty hacks involving uninstallation of other Apps or anything similar to that.

The hacky ones out there had come to full stop at development, it's CoverScreen OS which finally showed a real way to display over cover screen, added universal ability to add any widget and a ton load of other features.

Go ahead and try it out! :)

Hi there! To be honest, the existing pricing already is very hard to sustain the development efforts, because only a very tiny fraction actually contribute to the project and this is so niche that the small set contributors actually is really tiny. That being said, you can always email me, I might be able to do something for you! :)

BTW, even the most plain phone case for our Z Flip series costs more than the base lifetime subscription to CoverScreen OS, and here we are talking about a software that is continuously updated (released over 117+ versions so far) and enhances the experience of our $1000+ phone.

Hi there! Check out the latest version, it has now a one tap widget addition interface, directly from cover screen.
  • GMail text field - noted.
  • The keyboard has two options to enter field, one is a simple 'enter' and another is 'enter & send' (the send icon.) If one of them doesn't work, the other one should, try it out!

    I agree with you. Dev makes a reasonable point that the user adaption for z flip is low and plus for this app would be much lower but the price for a user is quite steep.

    I could buy 2-4 apps using at the same price for this one.
    And especially so since the app is listed as “Beta”.
    👎🤦‍♂️

    I am trialling the free version of csos so maybe that is why. But no, I have tested it quite a bit and I can only seem to add a custom quick toggle that basically acts like a widget. I need to have bixby routines turned on to be able to add the quick toggle. And it will only turn on or off a specific routines. Not actually turn routines itself on or off.

    Hi again! I am still confused with your query! Do you mean, you want to be able to turn on/off the feature 'Bixby Routines' itself? (Like, from the Quick Toggles on main screen?) And if yes, why? What's the use case? Give me an example of what do you exactly want to accomplish, may be I will understand better then.

    When I share live location on WhatsApp, the coverscreen shows on the screen that I'm sharing a live location and double tap, single tap, swipe (right and left) doesn't work at all.

    Can you post screenshot of the cover screen when you do the location sharing? (You can take screenshot of cover screen while folded, screen turned on, power + Vol down.)

    Hi Jagan2,
    Thank you for this great addition to Flip series. You really made a great use of the Small screen.
    However, I am wondering why do I need to login/share my account information in order to be able to use the app? A few apps that require users to login with their Google account to be able to actually use it (except apps that require login). So what's the reason behind this?

    Hi there! You're welcome, glad that CSOS is able to make the cover screen more meaningful.

    The login, originally was created to allow only a handful of users an 'early access' to the App, it continues to stay there to avoid unauthorized usage/tampering of the App itself besides for future ability to save and restore settings. Right now, the login doesn't actually access/use any information other than email address for verification of 'Support Dev Pack'.

    Hi,

    I've been using your app and loving it. I had issues with widgets not appearing on my Flip 4 but it was fixed in Beta 1.1, although after I got updated to Beta 1.4, I have the issue come up again and widgets won't show. Could you please fix that issue again? I will also be subscribing to the lifetime access once that's fixed.

    Thanks.

    Hi there! Did you try to restart phone? Everything should be working fine. Let me know how it goes.

    I am thinking of getting a Z Flip and indeed this app is the only reason why I would even consider buying the phone. I tried the cover screen in the store and was utterly disappointed by how little Samsung made of the potential of the cover screen. I don't understand the discussion about spending 20 $ on your app if your app is what makes the phone worth any money.

    I have a few questions, though:
    1) Will there at one point be more functions available on the Z Flip 4 than on the Flip 3? I am considering just buying a Flip 3 as they are heavily discounted right now.
    2) Will there be at some point the possibility to use any keyboard on the cover screen? I use Messagease which seems perfect for such a small screen. It is as compact as a T9 but allows for super fast typing.
    3) When trying the Z Flip in the store, I couldn't use the hardware buttons to take a picture using the cover screen but had to use the touchscreen. The hardware buttons could turn on the camera but not take a picture. Does your app allow to remap the volume keys to take a picture? If no, do you think it is a change that is doable?

    Hi there! I am glad that you find the App worthy of the $20 for Z Flips!

    Responding to your questions,
    1. I can't comment behalf of Samsung ofcourse, but, I don't think software wise there is going to be any massive difference in features especially with respect to the cover screen.
    2. There is a possibility, but it requires few tweaking from Samsung itself, which I highly doubt they will do (atleast not with Z Flip3/4). So for all practical purposes, CSOS keyboard is the best you could get for the lifetime of Z Flips.
    3. You can indeed press the volume down button to take pictures on cover screen.
