6 months ago, usb port fell completely out the n900. They repaired it. Then it happened again last month. wait 2 weeks for it and was chuffed they sent me a brand new n900. Only to find out the proximity sensor is stuffed. Always showing closed rendering the phone almost useless as a phone as the screen is always black on making and receiving calls. I'm certain its that after a lot of reading up, testing, reflashing rootfs AND emmc, and testing again. Its constantly stuck on 'closed' state. So now, what do i do? Send to nokia again and chance that they repair or send me another one? last thing i want is to receive an E7. Advice appreciated?
