The MT6582 and MT8382 have the same core architectures, CPU speeds, GPU, network connectivity capabilities, etc. The MT8382 is in MediaTek's tablet series of chipsets, MT6582 is for smartphones, but capability-wise, they are the same.
If the device claims an MT8382 chipset, then it is a tablet. The only problem you will have there is whether it is fake or not
Are you planing on buying a tablet/phone?
I hope you don't mind if I share my opinion here...if you are after a tablet or a phone, stay away from Aliexpress (and definitely stay away from generics or clone models). I mean, Aliexpress is a great source of various items, but when it comes to phones and tablets, there are way too many horror stories about faked specs and zero customer service
There are so many good China phones and tablets with reputable brand names that have great specs. And you have a good selection of online stores right here in the forum. The sponsor stores have great promos every now and then. I don't know exactly if the Ulefone Be Pro $134/$135 sale is still going on, but its a damn attractive sale.
I recommend you take a look at Gizbeat phone reviews. See if there are any reviewed phones that fit your required specs and price range. the THL4000 got a whole lot of love because of worldwide 3G + monster battery + $85 sale price. Although, from the photo of the device you are showing, I am assuming you want a large screen, so the THL4000 might not suffice
Anyway, there are a bunch of other reviews on the site
www.gizbeat.com take a look. Of course, you can always post a list of criteria you want in a phone, I'm sure a lot of people here will be able to give you some good suggestions.
Well, like I said, I'm just sharing my opinion...I hope you reconsider buying from Aliexpress. I'm sure there are still legit sellers on there, but I've just read about a lot of harsh user experiences about faked products. I'm sorry if I seem very negative about it, its just that reading those kinds of stories gives a very very nasty taste in my mouth, and its terrible that there is no way to help out those users.
