As a Samsung China fan, I know a lot about chinese version Samsung phones ; however I live in France so I also know a lot about the most common version of Samsung phones which are the international variants.
So, let's talk about chinese version Note10+ which has some pretty cool features that we can find nowhere else (btw I will get one in december when I go back to China so this thread is only about specs)
In China, Samsung only provides Note10+ 5G version, the model number is SM-N9760 which is a snapdragon variant. You may think that it is just the same as US version Note10+ 5G with a different software, but it is not exactly the case :
First thing is 9760 is the only Note10+ 5G in the world with dual sim card support. Second is that since Galaxy S10 series, Samsung flagships sold in China are the only in the world that support L1+L5 dualband GPS and 9760 is no exception.
In the box, Samsung provides a transparent case and a 6-month screen replacement reduction (only usable in china)
On software side, 9760 is also different from international version as the CSC it runs (CHC) has many features you may want to use even elsewhere than in China ; let me talk about the new additionnal features on 9760 (I will make another post about the CHC software improvements later) :
Bixby gets a new function exclusive to China that is Bixby Touch (but I have to test it to know if it only works in Chinese or if it is available in other languages) : you just have to long press on any screen to get shortcuts to related apps or services : for example, if someone send you a message with an address, a long press will let you open the maps app directly from there without having to copy/paste or doing any other action.
Samsung Pay gets a new smart door card function, which can let user access their building with just their smartphone.
Of course, it has all the other features from CHC rom that I'll detail on a later post.
And for those who want to know about the occidental services that are also supported, I also have the answer :
Google Play services are preinstalled ; by default, they're not activated but to get Google apps, you just need to download a play store apk and it will work just fine.
Instagram mode works : I tried it on a smaller version Note 10 in China, you just have to install Instagram and clear camera data and it will work just as on international version.
You get your local Galaxy Store because the phone region is defined by your sim card.
However, some features won't work or not completely : for example, Samsung Health will only sync if you have a chinese samsung account and you won't be able to compete with people using non-chinese Samsung Health app
I do NOT know if Samsung Pay works with non chinese cards but I will try it when I get 9760.
You cannot get the "Secure Wifi" feature as well as international version of smart call.
Finally there is no ROM you can flash because 9760 is actually a Chinese-exclusive variant (but that may change if Taiwan gets 5G model)
Personnally I think Chinese Note10+ 5G is the best variant you can find ;
Snapdragon 855, L1+L5 dual-band GPS, Dual-SIM, some cool exclusive features and the ability to use all the features we already use and love... for a cheaper price tag as it is sold in China cheaper than 4G variants in Europe...
