Pretty sure this is a straight up scam, the RAM changes depending on which site you find it on with none of them showing 20GB of actual RAM, and the website for 'doogee' doesn't work
It's not i've bought two of them years ago because they have a decent spec rugged phone. The s60 was bulletproof and lasted ages and even a drop from standing height on concrete. I upgraded to a later model (i think s90) and that was a piece of shit. The quality control is crap, don't expect software updates but if you get a good one the hardware is great. So not a scam but i would stay away.
Hard to see why to get this over a more mainstream phone where you can at least hope the software is not too flaky. Unihertz has some phones with special hardware features like tiny size or huge batteries. Doogee has had some of those phones but this one is just normal, 5100mah presumably non removable battery. Ok 20gb ram, but who cares? No price mentioned.
Doogee, make a phone with removable 18650s and I'll pay attention. Or a phone that runs GrapheneOS out of the box, or anything interesting like that. This isn't it.
Feels like too many phones try to be something special but are afraid to fully commit as fully committing would make the phone look different than your typical phone and often with tradeoffs in other areas.
When i got my phone i got it because it has a huge battery(21000mAh) that lasts about 5 days on my regular (quite heavy) use and it is fully waterproof (rated for heated pressure washing and i have tested that it can easily survive being underwater in a hot tub, i also have a habit of sometimes washing the screen with water and soap).
The tradeoffs are that it's built like a brick, weighs half a kilogram and all headphone jacks don't fit the port because the waterproofing requires the port to be recessed.
That phone just seems like your regular phone with an above average battery
Unihertz Tank 2? I sort of want one of those. The Doogee's battery isn't especially above average these days. The Motorola budget phone I use now has 5000 mah.
