Loudspeaker doesn't work any more and sound has become very faint

[Dorothee_Mulhausen]

As I said above in the topic: the loudspeaker doesn’t work any more and sound has become very faint. I have tried rebooting the phone (no use) and reinitializing the phone (no use either) - any ideas?
Apart from that, I also get the occasional black screen where I have to remove the battery in order to end a call and a little signal when I try to reboot my phone that nothing is happening (that’s really worrying).
I am open to suggestions !

Go to settings → maintenance and recalibrate your proximity sensor.

Sounds like dic:recoverymode. You usually only get there if you press power and volume up at the same time. It could also happen if your volume up button is stuck during rebooting. Take off your cover and see if it happens without the cover too. If not check the buttons on your cover.

Slim Case - Reboots and Button-Issues

###Original Post: Hi, I received the new slim case this weekend and immediately applied it to my FP2. It all fits well and makes the phone more appealing and remarkably thinner but later in the afternoon the phone went suddenly into a reboot with all apps checked and installed again (like with an OS update, black screen etc.). After a few minutes the phone comes back to normal but this happened the last days a couple of times, every time without a proper warning or clear reason why it did so. I…

Unfortunately I haven’t found a video or pictures on how to change the buttons.
But it’s not to difficult, if you have some patience, a steady hand and can work with tweezers or the like:

The buttons are fixed like this.

1. Take off the buttons (camera and power) by gently removing the transparent rubbery strip from the black pins (it works like a press stud/snap fastener).
2. Take the power button (the surface is ridged) and put it in on the place of the camera button. Take care to place it correctly, the rounded side goes into the back cover. (It can be done the other way around; believe me, I’ve been there accidentally . You realise your error, as soon, as you try to attach the cover to the phone again. Then you’ll have to do it again. ) Place the holes in the transparent rubbery strip over the black pins and use tweezers or maybe the tip of a ballpoint to push it into place. Do not use to sharp an object, as you don’t want to damage the rubbery part, because that might result in cutting it and you needing to buy a new slim cover (buttons are not sold seperately as far as I know)
3. Take the camera button (the one with the smooth surface) and fix it the same way in place where the power button was before. Take care of the orientation of the button as well. It’s the same: rounded side into the cover.
