I was having MMS issues with my moto X. They would randomly send or not, some would say sent but didn't. whatever I called Motorola and was told to ask tmobile to revision my MMS or something. it didn't work so I called Motorola & told them and they shipped me a replacement phone. I just received it and to my surprise and great delight!! it's running 4.4 not 4.4.2 which moto practically forced me to update to!!
Can you say OLD BOOTLOADER!!! and I hope my MMS works again.
also 2 things I noted.
1. The moto X screen is supposed to be seamless with the body of the phone, meaning when gliding your finger from screen to the side bezel of the phone it should be silky smooth and your fingers should feel no friction at all. My old moto x, the one being sent back contained some friction when gliding to the right side.
2. (pic included below) the new one, I just received 20 minutes ago has scratches on the Sim card tray?!?!? wth! i honestly could careless but there may be some quality control issues in their Texas plant.
Carry on and use this info as you wish.
