i’m looking for a watch that’s cheap but something that’s pretty recent, like it has 4g support but also a newer Android version (android 8/9 is fine)
from what ive seen the most common smartwatches that have android are those that have the design of an apple watch ultra
S100 the best out there for me.Chinese version a winner with workarounds for google etc
and where can i find this supposed S100 Chinese version smartwatch? from what i can tell there’s little to no info on this that makes it identifiable, as searching for it brought up other smartwatches that also share the same name
Found exactly what I needed on Alibaba — check out this product! 
2026 S100 Ultra Smart Watch GPS NFC for Call Fitness Tracker Sports Android IOS IP67 Waterproof | Alibaba.com
also are there any other similar watches out there that are easier to find?
do they not sell these on aliexpress?
Yes but for £ 130
been in touch with the ‘manufacturer’ about his one, https://szhhtech.m.en.alibaba.com/?spm=a2700.details.0.0.3cb2710fn99DD2&wx_navbar_transparent=true&wx_screen_direc=portrait&productId=1601764187855&from=detail_company_card
they’ve confirmed it does not have band 20 for LTE, though can be customised with band 20 for a bulk order
the chip always support everything just to enable or not
Would it be possible to enable band20 by some kind of software mod?
flashing nv partition can if you have file that have it enabled
