Random activation of speakerphone and microphone muting

I have a problem with my 9810 which has been happening more or less since I got it two years ago. I'm very happy with my 9810 but the frequency of this issue is increasing. The sound during a phone call ceases to properly function and the only solution is a battery pull and a complete reset. So far this has not happened during a real emergency, but that is indeed feasible.



- Either as I answer an incoming call or immediately after dialing out, instead of the normal speaker being active it's the speakerphone that is active.

- At the same time, the microphone goes mute.

- I normally have the volume at 100% but when this happens it shows the volume bar at 50% with no possibility to change it., it's just stuck. So when I make a phone call and I see the volume at 50%, I know I'm in trouble.

- The display on the screen shows the speakerphone being inactive despite this not being the case, and there is no way to activate or deactivate the speakerphone, it's just stuck.

- This never happens during a phone call, always at the start.

- Any subsequent phone calls will have the same problem until I do a battery pull and reboot. The problem might reappear in 2 days or 2 months, it is seemingly at random

- I have used 3 OS versions and all have the same problem. I am currently on v7.1.0.825


Any help on solving this issue would be appreciated. It's an excellent phone all around, but the frequency of this glitch is increasing, and I am worried it might one day happen during an emergency.

Re: Random activation of speakerphone and microphone muting

Hi and Welcome to the Community!

I recommend that you attempt to boot into Safe Mode:

  • KB17877 How to start a BlackBerry smartphone in Safe Mode

It may take you multiple attempts to get the ESC key sequence (press/release/hold) correct, so be patient. When successfully into Safe Mode, see what happens.

If the behavior ceases, then think carefully...what happened just before this behavior started? A new app? An update? A Theme? Something else? Think carefully as the smallest change could be causal...and attempt to undo whatever that was.

But if the behavior continues in Safe Mode, then you may need to consider more drastic actions -- WIPE, OS Reload, BBSAK Wipe/Reload, and the "Bare Bones" OS Reload Process. To prepare, you should be sure that you have a full backup to your PC...please review the Backup link in my auto-sig on this post for instructions.

Good luck and let us know!
