This thread is only for devices running on the new firmware upadte (4-13-11)
If you have a bug with your device please report it in this thread. There are many category's of bugs the ones we are looking are bugs that occur in many devices and can be repeated. I will add them to this post so others will have a quick reference to what to watch out for. Not every issue reported will make this list. Just because something is not working on your device that doesn't make it a reportable bug with this device. A hardware issue with your device is not going to make this list. A compatibility issue with your car bluetooth, your headphones, etc... is not going to make this list. Please do post these issue in this thread or start another someone might have an answerer that can help you but don't expect these issues to make the official bug list.
1) Some Lumias have a purple hew at low light
2) Camera button and Volume buttons don't work when the screen is off sometimes
3) Some are still reporting data issues after the update
