    I have the device and I want to add:
    1- They updated the security patch to Feb 10, 2020.
    2- The manufacturer’s name is Deltainno (Model DT1901A) It’s not Smartisan but they published it as Smartisan Nut Pro 3
    3- the software does have bugs like widgets being missing and you will need to reinstall apps so the widgets appear again ( It’s not that polished ) but it still has some good features like OneStep 3.0 and it does notify when getting emails or whatsapp messages…etc except for Telegram messages)
