I also had the traditional problem with this phone: swelling battery. The first time, I took it in and had the battery replaced by a repairman. This time, it was stuck so bad that the little aluminum pad over the push button switch fell off. I managed to take the screws out, but I didn’t see the “pry points” that the disassembly did with the guitar picks. Where is it, so I can replace the stupid metal shield? (It does seem to work without it…BUT it must have had a reason for being there.) By the way, if the phone fails again I will replace it with a Samsung model. Primary reason is, I have to hold the %#*@ thing to my car’s air conditioning duct so the GPS will “occasionally” start working. I need a more reliable GPS, and I can’t use my tablet on the road because it doesn’t have cellular data, and a wifi hot spot costs too much just for using the tablet for GPS. (And no, the phone’s wifi hotspot won’t work because that would require Verizon service (I use Tracfone).
There is a little piece of yellowish clear tape - presumably heatproof for the inside of the Mac Mini - that holds the little coax antenna connector onto the card. No one knows what this tape is supposed to be. I know common black electrical tape won’t stay long. I will attempt to use medical bandage tape and hope that it works. But this is something should be sold by someone.
