BlackBerry Z30 don't switch call to the speaker using the navigation. Screen went black accept after phone call.

I have this problem no need of me.

While driving and use any software of navigation, such as:

1. built in maps

2 Waze

3 NavFree

If someone calls me, I can take the call. But immediately, the screen went black.

I can't switch the call to the speakerphone. After random seconds, to switch screen might look for a second glance, and then the entire screen turned black.

Although it is black screen, I can't do anything, including trying to drag up to close current app/call.

Maybe it's something to do with the Navigation periodly software disables screen timeout?

Hello, Yes,.

Is this the same problem as described here:

Discussion on how the screen turns black during a regular call, it is impossible, for example, to listen to a call and to have the keypad remains lit, so you can press the right numbers while dealing with an automated reception, was doing phone banking, or using any other system that relies on automated messages.

The problem came down to how some people take their phone (especially when trying to listen to the guests and press the right button at the same time).  The solution has been to hold the phone differently.  So my question would be whether the phone is blacking out because of the very special combination of things happening in your scenario, or is it blacking out because you're online and proximity sensor of the phone thinks you're holding it to your ear (and think that when you do this, you want to have blackened keypad).

    I tried the clean boot and now the hard drive works simply and screen went black. The mouse still moves around the screen without any outher work keys? That is what it is?


    You will need to reverse the clean boot, as it is either incidental compared to
    the real cause of the problem. What, where you try to fix initially using the cleanboot?

    You can access Mode safe? Repeatedly press F8 as you start? If so you can try the configuration - control panel
    The Device Manager - graphics card - Double click on - driver tab - click the driver UPDATE - then
    Right click on the device and UNINSTALL - REBOOT.

    Another method to try to get to the desktop (try in normal Windows Mode without failure) is
    CTRL + ALT + DEL and the processes tab find EXPLORER.exe and COMPLETE the PROCESS on this subject - and then
    on the Applications tab - lower right - new task - type in EXPLORER.exe. Safe mode is reached
    by tapping F8 as you start several times.

  • Change the resolution of the screen and the screen went black

    Then I tried to change the resolution of the screen and the screen went black.  I tried to restart, plug in my HDMI port on my TV... Nothing.  So I went with a system refresh (yes I'm sure it was a refresh and not a restore).

    The fact that there is no integrated procedure to detect the moment where that happens and return to the old resolution is annoying enough...  But now after that choose the system update and it would be only to reset the settings to default back and keep all the files (as he said it would be), I am extremely frustrated to know that it has deleted ALL my programs.  Program E-v-e-r-y.  This means that Chrome, Firefox, jGrasp, AutoCAD, all my programs Microsoft Office, all my Adobe stuff, my Visual Studio and so much more that I'm not naming.

    I REALLY hope there is a place where they were stored so I don't have to reinstall everything manually.  If not, then wow, Microsoft... We finished.

    Unfortunately a refresh as he said, only maintains personal records (program data), the data can be located in the "in the"Windows"folder windows.old folder normally C /: Drive, all modern apps should be kept."

    All programs of office/legacy (Chrome, Firefox, jGrasp, etc.) need to be relocated from their original sources

    Keep all of your programs, personal files (data), settings, the best option is to create a "Disk Image" - see link below for info.

  • I was running Mozilla firefox on my computer until two weeks ago. At that time, the screen went black and now I am not able to use it.

    I was running Mozilla firefox on my computer until two weeks ago. At that time, the screen went black and now I am not able to use it.  When I click on the icon and open to the top it says cannot load and a flag of resolution comes up saying it can't run a resolution less than 1930 x 2300. I have no idea what this means and how I can solve this problem.  I thought that maybe the application was bad, so I deleted and then added it back on and it does the same thing.  I even did a restore of the system to try hard but nothing I did the work.  So, how can I solve this problem.  I'm not a computer genius, so he must be explained in simple easy to understand instructions.


    I suggest that you view in Mozilla Firefox community because there seems to be a Firefox problem.

    Some examples of the problem:

    «I can't open Firefox, it says could not load xpcom.» Who is wrong? »

    "I get an error"Unable to load XPCOM". I know that I can reinstall Firefox, but how do I save my favorites?

  • There is no user switch option on the login screen

    Good morning/afternoon

    Last night, I tried to connect to my Windows Vista laptop.  At the time I didn't realize it but I entered the wrong password, instead, I thought I was trying to log using the wrong user.

    I have advanced and dial-up user log-ins and it was at that point that I realized that the password has been my problem from the beginning.

    Right now I wanted switched back to the user login, but the ability to "change user" is gone.

    The only way I can access this laptop is with this specific user login.

    Any ideas?

    Thanks in advance for the help.


    It seems that if you somehow locked the system and when it is done it can only be unlocked by the user who has locked (which is why you see a log on option instead of a disconnect option and pushing the logon option gets you only to this one screen because it is the user who put in place the lock.)  This is normal and the way it's supposed to happen.  You can not change user if the system is locked by another user.  Once you login, you should be able to then go to the Start Menu and change user because the system is locked is no longer.

    If change username does not appear as an option in the start menu and the problem is not that the system is locked, then it may have become disabled.  Here is a procedure to re-enable the switch user option in the start menu if it's missing:

    If you want to change username (and don't mind close all windows for the current user, not), then you can press ALT + F4 and which will eventually wear a shutdown window.  Click the arrow next to the selected option and other options appear.  One will be to change username.  Select it and click OK.  The switch user should start.

    I hope this helps.

    Good luck!

    If you don't see it still, look at the Options > advanced > Applications. Do you not see it listed there?

    2 is it hidden? On your home screen, press Menu > SHOW ALL, so that ALL DISPLAY is checked.
