    Hi all I've updated my S4 to kitkat 4.4.2 and a problem arrived. Whenever the screen is locked it doesn't display the caller I'd on the screen as before you have to unlock it and then se who is calling you. Is there any way to solve this ?

    Thanks in advance to anyone who answers.

    Thank you for your post.

    There are currently 28 different models of the Samsung Galaxy S4 and over 2,000 different stock Samsung firmware versions, worldwide, covering 5 different Android platforms, Android 4.2.2, Android 4.3, Android 4.4.2, Android 4.4.3 and Android 4.4.4. Not all issues will affect all models or firmware releases and your answers to the following questions will help in the forum's answers to your specific query.

    #1 Could you post your Model number and Android version...

    To locate these, go to...

    Settings > More > About device > Model number and Android version

    This will give you the model of Samsung Galaxy S4 that you have and which Android version you are on.

    #2. Your current Firmware, (not just Baseband), version .

    To locate your current firmware version, go to the stock, Samsung, dial pad and type in...


    This will give you your, "Version", details in full, usually 3 lines of information, AP: CP: CSC:, which may all be relevant.

    *** If code *#1234# has been disabled on your firmware, you can download and install, free from the Play Store, Phone Info and it will give you, under Firmware Info... PDA, Baseband, CSC, versions.

    #3. Also helpful would be your carrier, (service provider), location, (UK, India, Russia, USA, etc: ), and if your phone is rooted or not and running a custom ROM, (give details).

    Thanks. The above helps us to help you and hopefully someone will be able to reply to you shortly. :)

    (Tip: You can go to the green bar at the top of this forum and click on, "User CP", which will take you to your User Control Panel and then select, "Edit your details", under the heading, "Your profile", on the left hand side. Here you can fill in your model and firmware under, "Current devices", in, "Additional Information". This ensures that your device details are shown under your user name on the left, in every post you make. You can update this as often as you like and will help other users immediately identify your current phone and firmware details.)

    Thanks for that Tequihua!

    It would appear that you have the SGH-i337M version of the Galaxy S4 which is similar to the Canadian SGH-i337M and a close relative of the U.S.A. variant for AT&T, the SGH-i337.

    Since you do not have a rooted device, I have asked our kind, helpful and friendly Mods, (don't forget my invite to the Mods and Guides Christmas party lads), to move your post to the General forum, where you should receive more assistance.

    Good luck!
