This phone is very slow. It auto update every few days and sometime it's a gig update. In a month time the update have nearly ate up the whole 16 gig memory. There is no way to turn off the auto updates. It is waterproof to a very shallow about 3' of water only if you remember to have all the port cover closed. The phone legs very bad. Getting ready to factory restore to get memory back and the root the phone so I can put apps on the SD card. Bottom line I don't recommend this phone and wish I would have researched more before buying it. I do like the dual sim which works well but only allows you to select 1 sim to be 4G service and the other Defaults to 3G or 2G.
You get a one time warning after unplugging a port that the waterproof flap is open but no further warning if you forget to close it. Also if a flap works itself open it will not warn you and is no longer waterproof. Hope this helps anyone thinking of buying one.
