On my 2nd evo3d and I think third time's a charm

[furiousgtz]

I still have great hope for this phone and I still love it.

My first phone had speaker problem and had hard time making phone calls. It would connect but no voice. I got it replaced and my second evo3d is just perfect! however this is day 2 and phone have small dirt particular building up lower screen just above those soft keys. Phone sits in my pocket. I tried canned air to blow some air see if it goes away.

psychologically my mind is telling me this is not good get it replaced. What should I do keep it the phone works great. This time the speaker quality is actual better than my first evo3d.
