jctoad hold the set button. cycle through settings to temp. plus or minus to switch between c and f

jctoad probably because you're receiving device does not have a 5.1 decoder in it. I think Bluetooth will support 5.1

jctoad I was trying to figure out if it would work on AT&T. After some research and seeing your question, I figured out that Assurance uses Sprint which uses LTE bands 25, 26 and 41. According to BG, none of them are covered by this phone. However, keep reading to the end. The bands listed here are NOT North American networks. There is one exception that I found. One of the phones bands, 17, is supported on Bell, Rogers, Telus and Freedom Mobile in Canada. That's from wikipedia search for LTE_frequency bands Deployments by region However, another site, kimovil, (search for doogee x95) says it does supports 9 of the 16 American LTE bands. I don't know. I just ordered mine and selected the Other Area version. Not the default EU version (the bands listed on BG are EU bands and many other countries but not US.) However, the bands listed don't change if you select other area so I don't know. If it works in US then great. Otherwise I just won't put a sim in it and just use it like a tablet. At that price and size, I think it's a tablet killer. BG says 30 day return, but I don't know how much of a hassle it would be.
