First of all, congratulations on Your great App!
1 (or 2) features, that I would find helpful (I don't know, whether its possible): it would be nice to have the opportunity to assign the same picture to multiple contacts (as batch) or at least to a contact group.

Thanks: Andy

b- i haven't seen a theme with this and previously in my theming questions lowveld mentioned it wasn't skinnable - so i assumed it continued not to be. ...

New update coming tomorrow, too tired to test everything properly now. Current changelog:

- option to hide call time
- speaker button themable
- Added swipe gestures:
- Global activate/deactivate
- Swipe up to bring phone dialpad
- Swipe down to go to default phone interface
- Swipe right to answer call
- Swipe left to reject call

...

This is the changelog from the penultimate version ;)

V 1.4.0 is out

Without further ado:

V1.4.0
- You can hide parts of the callscreen, like buttons and backgrounds. In the limit, you can even leave only the picture, no name, number or buttons.
- You can set and preview different default HD default pictures for Unknown contacts, for easier identification.
- (Licensed) You can apply different themes per-contact, individually. Together with a fully transparent theme, you can achieve true fullscreen for selected contacts: only the picture showing, and answer with swipe gestures. I'll be publishing a Transparency theme for this purpose at the same time as this update.
- Fixed issue where UCS would not show on outgoing calls (most seen on ICS 4.0.4)
- Rearranged UCS preferences into sub-menus, it was getting too long.
- Added one-time changelog poput to first boot
- Added a "Tips and Tricks" section to preferences, answering common complaints in market reviews.​

Also added a transparent theme of my own to market, don't know how long it will take to show up though...

Thank you all for your support, and I hope you enjoy!

Cheers

P.S. Tectas, your issue should be solved, but please confirm it when you can.

And one more small change...

Lots of people were confusing the "accept" button staying on screen after picking up a call with not picking up the call.

And I admit it's my fault, pretty bad user feedback. Anyway, just uploaded V1.4.1, only difference is that when you answer the call, the "Answer" button goes away and the reject button gets centered (pretty much the out-call layout).

Cheers

Thank you for this! \o/ That was really needed. :D

And one last question. Shouldn't the timer be activated once the phone call has been picked up? I made a fake call to a friend next to me to show him the application and the counter started in the second zero I called him, although he rejected it 10 seconds later.

That's open to interpretation. You can think of the timer as measuring the time you are actively occupying the phone line. On incoming, you only take action when you answer, on outgoing, you start the moment you dial the number and try the call.

On incoming calls the timer only starts when you answer. I can change the behavior on outgoing calls to start only when the other party picks up (and then the timer would be the time you are actually paying for the call).

As I said, it's a question of interpretation...

In which case I'd suggest that you have another option which permits the user to change when the call timer actually starts (which ever way they interpret it)

Just bought the paid version to support.

It states that you can sync with FB pictures, but I do not see an option to do this.

Forgive me if this has already been covered. The paid key clearly states this is supposed to be a function of the paid version

I'm sorry, but in no place do I say that. What is stated (copy pasted):

Setup UCS to use your current android contact picture as fullscreen caller ID. This not only allows you to not having to define a picture for every contact (or stick to a default HD picture common to all non-personalized contacts), but also allows you to change UCS contact pictures with 3rd party software (like syncing with facebook).

That is, UCS will use what you have on the phone, but facebook syncing is (for the moment) only possible with 3rd party apps.

I don't think the sentence is misleading, but if you want a refund, just let me know.

Cheers

What are the best dimensions to use to get fullscreen contact pics... Some of mine are getting cropped.

Sent from my SCH-I500 using XDA

The best and recommended way is for you not to worry about that and have this in mind:

- When you press "save" on the builtin image cropper of UCS, whatever is shown is what will be used. Including black margins at the top and bottom if they are visible.

So when you choose the picture fro your contact, just use the multi-touch zooming to make sure the picture takes up the all screen before you press save!

Cheers

Well technically, Facebook itself would qualify as a "3rd party app" as you are not the developer of FB.. which is the impression I was under by reading that sentence (3rd party apps meaning FB, Twitter, etc)

However I like the app, and I will not request a refund.

Quick question - the 'intercept outgoing calls' permission - what feature is that needed for exactly? I'm sure it's probably necessary however I would like to have an explanation if you don't mind, obviously that is quite a security breach and should only be allowed to the most trusted developers.

Thank you!

How do you think UCS is capable of detecting an outgoing call and show the fullscreen picture of the destination contact?

Ill change the text on the listing, I'm not here to try to fool anyone...

Cheers

P.S. Glad you considered me a "trusted developer "

I watch for a long time before I install apps with permissions such as this. I've been following this thread and market ratings intermittently for months, though I have to admit I have been lazy on reading all of the comments lately

I didn't think you intended to fool anyone, simple misunderstanding on my part (perhaps could have been worded more clearly, but you are taking care of that)

Thank you for the explanation, appreciate it. Looking forward to showing off your app and sending customers your way

Noticed something weird when I choose a photo from gallery as a contact photo - it deletes the photo from my gallery! Also, I cannot find the data folder for your app on my SD card anywhere. Can you help me out here?

    Ultimate Call Screen HD


    HD Full Screen Caller ID, Video Caller ID, Fullscreen SMS receiver and Call Blocker. The most complete fullscreen caller ID replacement and phone toolbox on Google Play, feature leader on its class, UCS is much more than a simple call ID app with big pictures. UCS combines:

    - Fullscreen Caller ID replacement with true HD pictures of your contacts
    - Full Screen Video ID
    - FullScreen SMS notifications
    - Fullscreen SMS Browser, including threaded mode
    - Fullscreen Missed Calls notifications
    - Unprecedented theming options, including 11 free themes
    - Contact picture manager
    - Call Blocker
    - Sensor-base actions such as rejecting calls by turning the phone screen-down
    - AND configurable swipe gestures just to be sure you handle your phone any way you want to.

    As recommended on www.lifehacker.com:
    "The features of this app are almost too numerous to list, but if you use your phone to make phone calls (you know, that thing it was originally intended for), it's a must-have."


    preview_hud_c.jpgpreview_ring_c.jpgpreview_buttons_c.jpgpreview_rotary_c.jpgpreview_stab_c.jpgpreview_sms_c.jpg


    In one app, you get:
    - Choose pictures from gallery, camera or link to Facebook friends using their HD profile pictures
    - Choose Videos from your gallery to use as full screen caller ID
    - Apply pictures to contacts directly from your gallery, with the android "share" function. Just choose "Add to UCS"!
    - Answer calls with buttons, sliding buttons, rotary buttons, swipe gestures... You choose!
    - Configure your phone to hangup calls, put on speaker or mute ringer simply by turning the phone screen-down!
    - Swipe gestures (reject and answer calls, reject with sms, reply to sms, ...)
    - Fully featured Call blocker
    - Fullscreen SMS receiver
    - Fullscreen Missed Calls Notifications, with dismiss, callback and answer functions, and configurable swipe gestures
    - Complete theme support for both call and SMS screens, personalizable per contact
    - Picture syncing of HD pictures to phone internal contacts
    - Privacy Screen: hide incoming call and SMS details from prying eyes until it's safe to pick-up/read

    Advanced Features:
    - Use your current android contact picture as fullscreen caller ID (Licensed only!)
    - Selectively enable only for outgoing/incoming calls
    - Sync your android contact database to use your UCS-defined callscreen HD pictures, or batch-upload a set of pictures from your sdcard
    - Hide parts of the call screen for cleaner interface.
    - Option to make incoming SMS show above lockscreen, including turning the screen on
    - Missed calls viewer
    - You can ALWAYS go back to the default phone interface during a call, simply by pressing the phone "Back" while on a call
    - Much MUCH more! Take a look through the available settings!

    Getting Started and Important Notes
    - To use the dialpad and other in-call functions, press the "Back" button on a call to bring up the default phone interface! Due to security restrictions imposed by Google, it's impossible for me to provide a working dialer during an ongoing non-VoIP call.
    - In version V5.0.0 and upwards, the model of the free version changed due to userbase request. Almost all functions are available, but there is a personalizable contact limit.

So UCS still shows exactly what you cropped and are seeing, plus it rotated the original image.
    - Fixed race condition that lead to a very "rare" FC (thanks to whoever reported the crash to google play)
    - Changed application icon


    V 1.0.1:
    - Restrict image editing and cropping to portrait mode to avoid FC until I rework it

    V 1.0.0:
    - Initial release

    Theming guide

    This is a tutorial on how to build themes for UCS. You will need the Android SDK and Eclipse installed and setup.

    I provide an Eclipse project which you can use as base and example to give you a quick startup. Note that there are other ways to do this without eclipse, but I won't get into that. But it is not enough to open the apk and just drop images into there (unless you decompile it, recompile it, and sign it). Well, at least not enough to use the full power of the theming engine: you won't be able to change text size, element position, and other stuff without recompiling.

    Take the attached eclipse project and import it. (please don't ask how to do this, there are numerous tutorials on how to setup eclipse/android SDK, and that is not the purpose of this post/thread).

    Template Eclipse Project: View attachment UCS_Template_Theme.1.0.0.tar.gz

    Alternatively, here is the compiled apk from the project above: View attachment UCS_Template_Theme.1.0.0.apk

    The apk is useful if you just want to change some images, and also if you use some of the toolkits around here in xda to decompile/compile apks. In fact, you don't actually need Eclipse to completely change the template: use something like ApkManager, and just decompile the apk.

    The theming does not involve java programming, that's why it works so nice with a decompiler: no smali editing. All you need for theming is replacing drawables, and editing xml files.

    When starting, take a look at the files in:

    res/drawables/
    res/values/

    The xml files in the drawables folder point to the actual images in /res/drawable-hdpi, and those are what you want to change
    The xml files in res/values control everything from text color to element placing. Take special attention to integers.xml, I inserted comments on it to make clearer what every key does.


    Play around with this, run it with the "run as android application" command with your phone connected to your PC if you're using Eclipse. Getting the offsets just the way you wanto to can be tricky.
    When you're done, just export as signed application and share it here if you feel like it!

    Cheers

    500.000 Thanks

    Hey guys,

    UCS turned 1 year old on last March 31st. What started as my mini-side-project for one of my ROMs, quickly evolved into something much much bigger. Those first couple of months were hectic. Just to give you a notion: 2 monts later, by the end of May, UCS had reached version 5.0.0, and 33 updates. Comparing the feature list on version 1.0.0 with what we have now, and specially the internals of UCS, is mind blowing.

    Today UCS has reached 500.000 downloads. Believe me when I say that not on my wildest dreams had I evert thought of reaching a number like this. I want to thank each and everyone on this thread, for all the input, ideas, and just plain selfless help so many of you provide.

    I don't consider UCS my own anymore, there's too much of you in it for that. And I thank you for that. For making UCS much more than I could ever hope to on my own.

    Cheers, and may we all be here for the 1.000.000 mark!

    Why the dafault phone will always show

    Ok, it seems there's a lot of discussions about the default phone interface showing up before UCS, and some misleading information floating around. I will try to explain in detail why it is so, and why it will always be so. This will be a long explanation, with some technical information that most will not fully understand, but at least you'll have a source point to investigate from if you so wish.

    1. Android is limited regarding "outside" app developers. No matter what google tells you, or how much hype is generated about it, the truth is that app developers are limited in some circumstances, comparing to full rom developers. As I am both, trust me on this.

    2. The telephony interface (the part of Android that actually handles the calls) is not exposed in the android SDK. This means that following "proper" development guidelines, something like UCS would not even exist. There are no available classes/functions to pick up, hangup, mute calls, or any other operations regarding call handling.

    3. Using some neat tricks, prior to Gingerbread, you could pretty much go around most of these limitations. As of Android V2.3, a further check was introduced: even if you manage to call the correct interfaces, Android checks if the caller is a system app, and if not, ignores it. This is why a lot of apps stopped working as of Gingerbread.

    4. With the current set of limitations, I was able to build UCS as it is now, working from Android V2.1 to V4.0.3. Yes, It could do a lot more if I restricted it to Froyo.

    So this is why the current feature set of UCS is somewhat limited when comparing with the default phone interface on your phone. This doesn't mean that in the future I won't find a magical workaround, but from where I'm standing now, it's not looking bright. But bottom line: It is currently impossible to fully replace the default phone interface, unless building the rom from scratch, to a specific device.
    Note that the limitations to what app developers can do with the telephony interface has been a topic of complaint and frustration with google for years now. Given that they recently made it even worst with post Froyo, it's not looking as they will change it for better. In this particular area, iOS is better. I hate to admit it, but... suck it up.

    So, trust me when I say we need the default interface to perform some functions. The following point, is why UCS only comes after the default. For this, you need some Android development notions. In lay terms, when something happens, the core system sends a broadcast to all apps interested that "something" has happened. This is the only way any external app has to know that a call i coming. The problem is that it is the default interface that sends that message, and it is capable of starting much faster than other apps.

    So when UCS get's the message that a call is coming, the default interface is already showing up. Even if UCS is able to appear faster than the default, it would be pushed back when the default appears, and then bring itself back up front again. So, there's no way to hide the default interface. The only time that you won't see the default interface will be when the phone is locked. In that case the overhead of the lockscreen can make UCS fast enough to finish the boot process before anything shows.

    Another thing: root access would give me some leeway to work with, but would not remove the fundamental limitations of UCS. I could try some more stuff, but it would have to be on a per-ROM basis, which pretty much invalidates even trying to do it in UCS. UCS is having about 5000 installations a day. If I screw up a condition that happens rarely, lets say for 1% of the users, I have 50 pissed of guys every day.

    Up to know this is the default UCS behavior. UCS taking 5 seconds to show up is not normal, and indicates some sort of problem. In my setup, I never see the default interface, it only takes less than a second to go away, and unless I'm actually looking at the phone with it unlocked, it's gone by the time I pick up the phone.

    This extreme delay could be caused by something else, I'll follow this up in further posts, and leave this one for reference for further questions about this topic.

    Cheers
