I have two (2) Moto-X phones, with Kit-Kat 140.45.5, only G-mail opens JPG email attachments. Comcast email and Xfinity App will not. Contacted Tech Support at all three, Motorola, Verizon and Xfinity. The only advice: use G-mail and/or K-9 Mail. Switch to G-mail address would result in immediate loss of business. Is there a fix planned at Google? Motorola 2nd tier help worse than 1st. Other Android devices I have with earlier Android versions work fine. There are many postings online stating same problem. Any advice greatly appreciated.
