[Android Q&A, Help & Troubleshooting] Alessandro999:
HI

AS WE KNOW MI 10S IS ONLY LAUNCHED IN CHINA AND NEVER WILL ARRIVE IN EU MARKET. THIS DEVICE IS COMPLETE ALL ROUNDED FROM BUILD QUALITY TO PRICE APART FROM SOFTWARE THAT CAN BE SOMETHIMES BUGGY AND LAGGY COMPARED TO STOCK ANDROID... I FOUND CHINA ROMS ARE VERY SMOOTH COMPARED TO EU ROMS BUT HAVE DELAYED NOTIFICATIONS AND THIS CAN'T BE FIXED IS PART OF MIUI SYSTEM AND KILLING SERVICES ( I TESTED ALL POSSIBLE IMAGINABLE SOLUTIONS BECAUSE IN CHINA ROM YOU CAN HAVE GOOGLE SERVICES EASILY INSTALLABLE AND 90% OF SYSTEM APPS IN YOUR LANGUAGE THANKS TO SET EDIT APPLICATION BUT REAL TIME NOTIFICATION OF WHATSAPP MESSENGER INSTAGRAM AND EMAIL ARE NEEDED

THE SOLUTIONS:

-UNLOCK BOOTLOADER AND FLASH EU ROM : HAS PLAYSTORE AND MULTILANGUAGES PREINSTALLED. ( MIUI 12/12.5 EU ROM LAGS A LOT OFTEN, IT FEEL A SNAPDRAGON 400 SOMETIMES). I NOTICES WHEN INSTALL A LOT OF APPS OR PHONE IS WARM IT START TO LAG/ THROTTLE. STOCK ROM DOESN'T SUFFER, EU UNFORTUNATELY YES....

-MIUI 13 EU I TESTED HAS IMPROVED PERFORMANCE BATTERY AND ANIMATIONS, IS USABLE BETTER THAN PREVIOUS I RECCOMEND IT BUT STILL LAGS HERE AND HERE ESPECIALLY SCROLLING AND CRASHES. EVEN STABLE BUILDS....VERY FRUSTRATING FOR HIGH END FLAGSHIP, REALME GT 2 NEO SAME SOC RUN WAY BETTER...

BUT... I FIND A BETTER SOLUTION ;) ... FLASH A GSI WITH DSU SIDELOADER ( dualboot no root ) or flash clean from fastboot , need stock china rom). MI 10 AND MI 10 PRO HAVE PROBLEM WITH AUDIO BASS DISTORTION ON CUSTOM ROM EVEN NOW THAT ARE UPDATED BECAUSE OF HIGH QUALITY SPEAKERS( INFACT XIAOMI REMOVE THEM IN MI 11/12 SERIES AND LOWER COST AND QUALITY, OK THEY APPLY HARMAN KARDON BRANDING BUT DOESN'T MEAN NOTHING... SO I DECIDE TO INSTALL LINEAGE OS 18.1 GSI MOD UNOFFIICIAL LATEST RELEASE BECAUSE LINEAGE HAS OWN AUDIO EFFECT MODIFIER ;) ( ON GSI DOLBY VIPER OR AUDIO TUNING DON'T WORK IN THIS MODEL), I OPEN AUDIO FX, I LEAVE MIDS TO 0 AND LOWER THE FIRST 2 ( BASSES) TO -15 AND LATEST 2 (HIGHS)TO -15 . THE AUDIO QUALITY IS FENOMENAL NO DISTORTION GOOD BASSES CLARITY

ROM IS WAY SMOOTHER YOU CAN INSTALL GCAM, APPS, NEED SOME ADJUSTMENTS IN GSI SETTING IF YOU WANT BUT IS DAILY DRIVER NOW

I TESTED 54 PHONE IN MY LIFE EVEN S20FE ( FOR ME STILL A COMPLETE PACKAGE) BUT THIS PHONE HAS BETTER BRIGHTER 1120 NITS CALIBRATED TCL PANEL 0,4 DELTA! BEST SPEAKERS EVER LISTED 1.2 CC ( BETTER ALSO THAN BK SHARK 4 PRO TESTED AND MI 10 PRO A BIT) HAS 30 W WIRELESS CHARGING AND REVERSE, 108 MP WITH OIS AT THIS PRICE, SNAP 870 TCMS ( NO THROTTLE STABLE PERF COMPARED 888 OR GEN 1 FROM SAMSUNG) ALUMINIUM FRAME 7000 S, ALL GLASS GG5, PREMIUIM CURVED 90 HZ PERFECT FOR SMOOTHNESS AND BATTERY( NO NEED QHD SINCE GAMES RUN LOWER FPS DRAIN BATTERY AND DON'T NOTICE), BEST LINEAR MOTOR BETTER THAN MI 11 TESTED... LOTS OF RAM UP TO 256, AVAILABLE IS GLOSSY OR SATINATED FINISH, 33W 4800 BATTERY 2 DAYS.... ALL AT 400$ !!!!!
