ive only purchased one ZTE product, i will never purchase another. You cant transfer video without third party support and even then it costs money to even do so. The Sonata is literally the worst phone ive ever had, worse than my Moderated Grand Prime and that was a PoS. Well guess it got worse when i decided to "upgrade" to a better phone and got this one. its a piece of ****. it runs like garbage, and should have never reached marketing for the general public. i will never recommend a ZTE product and i will make sure that everyone i know who is looking for a phone to steer clear of Samsung Ripoff ZTE, thanks! ill be sure to get a enw phone ASAP considering ZTE cant make a decent HARDWARE device let alone create software for the device to recognize the video files to transfer. SD cards dont even work, **** your company.
