Mi 9 Lite - Broken Display

no idea on data part as i do not have your device. does Mi have their own data backup and restore tool? i know that LG and Samsung does.

but it sounds like this is a hardware issue and it might be time for either a new phone or get the display fixed some how.

 

Looks very much like the screen is broken. A Xiaomi repair tech should be able to replace it, won't be cheap though. To backup your data, the phone needs to be unlocked, and with a busted screen and inoperable, that's not going to happen until it's repaired.

 

I have a Mi 10 Lite and a Poco F2 Pro both on MIUI 12. I've only started using one in recent weeks.

The default Mi Cloud backup settings are the first few on this screenshot which I just turned off on one yesterday. If you have your phone Mi account number it may help with a new Xiaomi phone.
Of course your Google account will also help.

 

just looked at https://www.ifixit.com/Device/Xiaomi_Mi_9 and they only have the MI 9 and not the lite....not sure if the screens are compatible or not.....most likely not.

 

Same one!

OP if like me you don't want to try, or more likely cannot source one (though it's a Samsung 6.39" FHD Amoled) - I would try Mi.com Support / Chat and request a repair price including shipping. I sent a phone to Nokia in another country under warranty (very quick) and one to Motorola (OK never got that one back); but Mi support seemed very eager to help on my account number issues.

Best bet, apart from buying another brand you like, is try Mi.com every few days for staggering price drops on a whole load of models going back to the 2019 Redmi 8 Pro (cheapest) to currently a £159 price in the UK with a possible extra £10 voucher on the new Poco X3 NFC. Though I also go for an Amoled screen if I can.

 

Sorry I missed this. Any news?
On my two models, with the screen working a long press on the power button brings up a first power screen with 4 choices. Press power off and you have to confirm on the next screen where the button is dead centre.
(Touch / digitiser probably doesn't work for you though).
I haven't figured how to fully get to Recovery Mode yet from Power Off.

As yours was not water damaged or shown any new cracking, perhaps a quick inspection by a local trustworthy repair shop might reveal a loose connection, but I don't about such things.
