Poco official store on Shopee and Lazada during flash sale.

but need to be very quick since 8GB variant always sold out within seconds.

Should be. The hot one during release was white didn't manage to get it. Now people wants the blue one I think

Regardless of color. 8+256 will sell like hot cakes. Coz stock always limited compared to 6+128.

Yes update and factory reset.

If you use stable rom, actually no serious bugs found, if had any then will get fix in next update.
So far I found Dark mode have bugs for EU weekly rom, xiaomi is trying fix it.

For weekly rom- Currently many users found Dark mode bug, color problem in apps, so have to manually turn off and use particular apps own dark themes.
No problem for stable rom.

Probably need to wait for MIUI 13 update, still based on my guess  .

According to eu forum is not void. This the 1st time i flashed to EU ROM, but we still can reinstall back to global rom before send for warranty.

* Our ROMs were approved by official EU distributor ABC Data to not void warranty for devices sold by them! (Of course, officially unlocked BL and no ROOT installed)
After flash, we can OTA (over the air) update, Update notification will prompt or you can check and click the "update" in Setting > MIUI version.
-Weekly EU ROM: download and install 3.5gb+- on every Friday / Saturday.
-Stable EU ROM: download and install 3.5gb+-, release in 1-3 months
You must unlock your bootloader in xiaomi phone 1st- have to wait 168 hours (7 days) then only can proceed unlock and flash rom. Everything inside will be format (for the 1st time flash rom. update will not format)

For installation, check post #1 at

Should be same, cause all based on China ROM.
I use weekly version so bugs fix faster than stable rom, of course new bugs may still found, won't end, but most are minor issues.

Wanna ask anyone with the deep blue ocean version, the back is matte like white or glossy like black?

Really? Now i have to think twice to get this phone.

Why my fb always log out ?anyone face this problem

Poco F3 support 4G+ on Digi?

I do get random reboot during lock screen after updating to latest firmware
