Review on 📱 UMIDIGI Bison Pro Rugged Unlocked Smartphone, 8GB+128GB Android 11 IP68/IP69K Waterproof Shockproof Phone, Helio G80, 48MP Camera, 6.3" FHD+ 5000mAh Fast Charge, Global Version NFC, Rugged Smartphone by DaHee Cheon ᠌

Works reliably. The performance matches the equipment. The quality of photos is normal - no better and no worse than similar devices. The pre-installed camera control program has a normal mode and an underwater shooting mode, as well as a photo editor. Only the date of the snapshot is not displayed on the image, although it is stored in the properties and in the file name. Therefore, for pictures with a date in the frame, I installed another “camera”. Good reception of the WI-FI signal: I took the network where others gave up. Geolocation works flawlessly. The device is equipped with tools: sound level meter; level; object height meter; magnifier; plumb; protractor; compass; barometer; pedometer; infrared thermometer. Two additional buttons on the sides are "quick access keys". Each button is configured to perform any action with one, two or three clicks - they can start or end the necessary programs, but these buttons were not useful to me. Some descriptions indicate that the Bison Pro is equipped with a walkie-talkie - this is not true. It only has a pre-installed program that simulates the operation of a walkie-talkie when communicating via the Internet. It was not possible to record telephone conversations from the line, that is, so that the voice of the interlocutor was also recorded. But the impenetrable Android 11 is to blame here. The external speaker, since it is recessed into the case for the purpose of moisture protection, is not very suitable for listening to loud music - the sound turns out to be muffled at the upper frequencies, and when the volume is added, it also rattles. I did not test its underwater properties. A couple of household falls on the floor from the table, the device endured without offense. But he showed real frost resistance. The device is heavy because it is equipped with a heating system. According to TX, it maintains performance at temperatures up to minus 20 degrees. In reality, at minus twenty-five, I wore it in the outer pocket of my down jacket - it works, it does not freeze. In general, I am satisfied with the Bison. In some review I read: "Buttons are pressed with the ear during a conversation." This is what I can't imagine at all. How is this possible?
