PS: there is a black rubber on the top right (I think it is the light sensor) that do not stay in place, for example during a call the screen goes black and returns to normal only after intense light on the sensor.
Sorry for bad english!
I know it has been a really long time since you posted this but I am hoping that you still check xda every once in a while. I replaced my digitizer and the front housing cover of my phone yesterday and am since experiencsing the exact same problems with my back speaker and a small strip on my phone does not respond to touch (this includes the bottom right button which is the menu button I suppose? The one with the two squares on it). Now my question was, since you tried again using double sided tape and was actually able to fix it, if I could just use a blowdryer to melt the new digitizer off the front housing without damaging it so I can reattach it with the tape. I did get the tape along with the parts, but because my front housing was already very sticky I thought that it would be fine to just press the touchscreen on there. But if I now heat the digitizer up in order to remove it, will I still be able to use it afterwards?
Also, with the speaker... I never touched that thing so I really don't know what happened to that. You talked about a loose connection.. what connection would that be? Because the only thing I see on that speaker are two metal parts sticking out which I think have to make contact with the two metal blocks that are placed directly in front of them.
I'm really desperate because I really can't afford to get a new phone so this needs to be fixed! Please help! If anyone else knows, also feel free to reply, but just.... thanks in advance people
