So I am sure many people have noticed when the tp2 is sitting on its back, say on a table, and the ringer goes off it is muffled. well, you can thank htc for being "smart" enough to design the back cover that way.
Now, how to fix it. This is a very simple and reversible fix to make your tp2 sound as if it was laying face down on the screen, gah!
1. First you need to go buy some of those round felt/sticky things you apply to furniture legs and the bottoms of rough objects so they won't scratch things. However you want small ones! so find some that are about .25 to .375 in in diameter and as thin as possible.
2. Next cut one in half leaving the sticky protector on.
3. Now take the two half and apply them right below the speakers on the back of you tp2. if you find black felt thingys they will match the black on the cover (at least for vzw)
Now your tp2 will sound 10x* louder when laying on its back (on a hard surface)!!
Only one know side effect - if you pop the keyboard out and tilt the screen up then set the phone down it will tip back ever so slightly. but this is due to where i have applied the felt thingys. i am sure if you play with the placement you can remedy this. as i do not use my tp2 like that i had no reason to move them
Hope this helps some audibly disgruntled people
