The problem with Xiaomi is that you don’t get OS updates and there is a lack of accessories and service/support locally.
To be fair that is the case with most phones that are not Samsung or Apple.
Nothing does have mail-in service at least, which is better than no service, but also a pain.
In the last 4 years I’ve had the Xiaomi Mi A2 Lite, the Lg V30 and the Sony Xperia 10iii. I basically got them cheap because I couldn’t afford anything about €350.
And while they were good devices, like the X6 Pro will be, I’m always frustrated at being stuck on an older android version, not being able to find phone cases (except on AliExpress but there are junk and you wait months to get it) and no repair services at all. No battery replacements, no screen or back cover replacements, etc. Even the 3rd party repair shops often don’t carry parts for these makes.
They’ll happily give you a 3rd party generic part which looks way worse than the original, but who wants that?
Hence I’ve made a decision that from now on I’m only buying Samsung because they have a 1 hour walk in service centre with genuine parts and the waterproofing is still there afterwards. Plus you get 4 years OS updates and 5 years security updates. And there are TONS of Samsung accessories wherever you go locally as well as online.
With such service I could have the battery replaced once a year, meaning top battery endurance and full waterproofing. Plus the latest OS update and cool accessories like magsafe cases for use in the car with a magnetic holder, diff colour cases for a different look on different days, large availability of chargers, cables etc. Plus if I eventually buy their BT buds then work seamlessly with them.
And they make great tablets, which will do the whole sync thing if you want.
I’d really encourage anyone to think about doing the same and not wasting time and money on these brands with no support.
You just end up buying a new phone every 2 years which is more expensive in the long run.
