Doogee V Max 22000mAh Large Battery Dimensity 1080 Octa Core 33W Fast Charging Rugged Phone

Its a reliable and sturdy phone with features you dont find ln other phones

Since a wireless update I can't use the night vision, and original camera software is freezing, and I can't use NFC wallet+bank applications.
Please solve the problem, give me a downgrade possibility, to repair my phone.
