Echo and overheating in Nokia Lumia 800 speaker

[Kumar esan]

There is a problem with my Nokia Lumia 800. The issue is about the speaker. While calling i can hear echo back. I know that it can be resolved anyway but other than this there another strange problem. While talking, the speaker gets hot. Is this normal?

You can open a hidden diagnostic application in your Luthat allows you can read some sensors in your phone. Normally this is only meant for developers and technologists, but it's also nice to see your phone works. The tool is a way to call by keying in a code on your Nokia. By application to the phone to go, and that # # 634 # on the keypad, you get access to the application. These states then determine whether certain parts of your phone functionality, such as the compass, accelerometer, speakers, camera, LED lights, etc.

I have my "problems" in the Nokia support forum and found there also posted. The more people there describe their problems better, such as the battery problem is also addressed why now so active, because there are so many complaints in the support forum were.
