The back on my Motorola cracked a month after I bought my phone, so no hope of ever opening this glued-together piece of shit. The camera's focus is now broken and the volume buttons get stuck sometimes (the buttons would be trivial to fix if I got the phone open, not sure about the focus but I imagine there's a replacement part available from some online store in China), but I refuse to buy a new one as long as the battery still works.

The best part is that the glass back is so slippery you have to use a case just to hold the phone comfortably, so you don't even see the back of the phone. Make it make sense.
