First i've used the Android 11 EVO rom and now i'm a happy Android 12 EVO rom user. I do check my data usage on a regularly base because i use my mobile hotspot a lot. But i do and did not see any excessive data usage.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] proconsul01:
This is what I see, the biggest data usage is YouTube Music, all apps together shown in the list are not more than 250 MB.

Again, I do not accuse anybody. Just stating facts.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] joeyhuab:
That's why I've been avoiding it the past day already. I'll continue to post updates here. Not there.

Exactly. Glad other users are finally speaking up.

Try listening to the other users. You are just paranoid. They've used my ROM since Android 11 and some even since 9 and 10. There's literally nothing to worry about. That's just google syncing your data for Google backup.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] proconsul01:
Google backup? 2GB? On my mobile data? and 43GB on my WIFI? I do not think so.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] joeyhuab:
Suit yourself. No one else should even be convincing you at this point. A single user won't prove thousands others wrong.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Temaki:
I made a Telegram account because some devices I use have chat groups there. But after I saw the there are people who misuse it to spread hatred and slander, so I stopped using it.

I do understand that some people are frustrated and need to vent, but it is inexcusable if other people get hurt.

I am happy that here on XDA folks are much more civilized.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] proconsul01:
I just want to know what happened with the data, is there a log somewhere on the phone? I do not want anybody to worry about their phone if there is a explanation.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] vvouliotis:
can you pls do yr own inquiry if you absolutely must? Don't come over and over again complaining about something and demanding others to do the dirty work for you. Believe me when I am saying it, we have been using it for so long and never came across what you shared in here.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] jottect:
I'm using latest Evo ROM (<<< THANKS joey!!! >>>)

I just checked traffic for my past whole month:

~ 3GB on mobile data;

~ 25GB on wi-fi;

So I think that maybe there is something on your phone (an apk) that may be using a lot.

Suggestion: try installing a DNS filter or something similar that will log your external connections and find the one that is sending your bitcoins and passwords to ROC :-)
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] proconsul01:
Thank you for checking! :)

It seems to be a bug after all.

I did the wrong assumption with the information from my provider (See picture).

It’s not 279,9MB left but 279,9MB used.

On my phone the data usage showed is not correct (Other picture).

I got a message from android yesterday and today that there was abnormal data use on my phone.

That is what let me think there is something terrible wrong.

I’m very sorry for my wrong conclusion, especially to joeyhuab.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] proconsul01:
Yes I know Joey and vvouliotis, I deserve that sad face, but I'm not afraid to admit it.

Still there is a bug in the ROM or some other software on my phone that can corrupt the usage data.

Than a mistake is easily made, so again, sorry for my mistake.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] jottect:
Everyone makes mistakes!

It takes balls to admit/apologize that you were wrong and take action to try to undo the damages if any...
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] joeyhuab:
I've said it from the start, that it's a bug with the kernel since Android 10. I hope you would've listened from when I said that but it feels like you ignored it entirely.

Hey @joeyhuab i do not know what went wrong in some telegram group. But just so you know, this is the first custom ROM that i have tried in my life and i salute you for your hard work. I have seen you fix bugs while you were down with COVID, you never took a break. I have seen your dedication man. I am thoroughly enjoying the ROM since day 1 and never felt the urge to switch to different ROM. I will stay in this ROM till this thread dies. The experience was that good. I could not donate anything but i will try in near future for sure. Love you man. Thank you again.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Peter the Great:
Lol, your provider uses such bad graphs. They show you a bar with 3 incomparable metrics: data, call minutes, and sms messages. You thought the large red bar meant it was almost full, when in reality it's saying that you use data a lot more than minutes and sms (they make it so that 1 minute and 1 sms are 1MB, that way they can compare it with the data, even though it makes no sense). Even when they separate the bars into 3 separate ones, it's the same thing. That's literally the worst design I've ever seen lol
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] joeyhuab:
Thanks for letting me know! Changes have been made to the NFC behavior for the next update.

I appreciate this a lot, sir. Thanks for remembering when I squashed bugs while I was in quarantine. With or without donations, I really appreciate users like you that stick around. You guys keep me motivated and keep me pushing forward.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] proconsul01:
In a way it make sense.

My provider gives me 6000 points.

I can get 1 MB, 1 SMS or 1 minute speaking with my grandma for each point.

But if you look at the graph you see a big red line so I thought wauw that’s a lot off data use.

Indeed now I see it, they expect you to talk a lot more than I do.

But I’m autistic, I hate to talk a lot on the phone 😊
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] blackout no1:
Sad to hear what's been going on. This is the first rom I've ever used and I'm glad I did. I don't expect updates constantly, as I usually only update if there is a significant update available. If people don't like how the rom is handled they just shouldn't use it. There are others out there to choose from. You do this for free at no cost, neither do you beg for any donations. Keep up the good work Joey, whether you stop supporting this device in the near future, that's fine. Everything good eventually comes to an end. Especially for keeping it going all this time.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] edddie23:
Nice to hear that. Now with NFC off battery life is very good. With screen off phone consumes almost nothing. And I have more than 4 hours SoT with only about 65% of battery capacity left.

Thank you very much for your work and your dedication.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] roysudip900:
@joeyhuab

1. I've used your rom from days of Android 10. I've checked my outgoing data and source codes multiple times and never faced any unusual behaviour. So I kept on using the rom on my primary device regularly.

2. I was on the telegram group but lost my excitement day by day. As telegram provides plenty of features, that became the greatest week point aslo. Groups became garbage.

3. We are using that rom regularly and not so fool that our decision would be changed as someone told something randomly.

4. Android has a huge user base and so many apps from 3rd party that it's very easy to mess up. Then it's not correct to blame one particular developer until some particular evidence reported.

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] vishvanjay:
I just clean flashed.

after settings up ok google, doesn't seem to work

it works only when I touch the mic.

like when I say ok google or hey google the mic icon shows up the top right corner. so it is recognizing my voice and responding to it but nothing happens after that.

I'm sorry if I asked a dumb question. using a custom ROM after a long time
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] NBDYbtw:
Works for me after clean flash using Global FW (although I don't use it, just tried it since some others were having issues) - it was also mentioned earlier that you might have to retrain your Voice for it so maybe give that a go.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] vishvanjay:
Tried it . only the mic icon is showing up in the notification but no assistant pop up. will try again with a new fresh flash soon

edit: fixed it by simple Google app cache and data clear also had to retrain my Voice
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] joeyhuab:
Hi everyone! We're currently migrating to 12.1 so expect some delays on the March update release. Features are slowly being re-added to ensure more stability. Basically, we had to recode the ROM from scratch cause Google made too many changes and we couldn't merge them on top of 12.0.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] zinko_pt:
No worries, take your time, we appreciate it anyway. Anyone who expects anything faster is high or loco.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] urbanmec:
Thank you sir.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] efx_9:
Hi dev.

Little bug: "Lock after screen timeout" option doesn't seem to work when "Power button instantly locks" is activated.

Great ROM btw
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] joeyhuab:
All features will be removed from scratch if you read my previous post. There's no use of reporting bugs if the ROM will start without the said feature.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] vishvanjay:
Looking forward to it <3
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] silpy:
hello @joeyhuab Im a bit late to the chat but i wanted to say please don't get demotivated by what you see on telegram or anywhere else. I've seen what goes over there and I think its safe to say that most of the users there are literally too dumb to understand what work you are doing here. I want to thank you again for your dedication for this rom and let you know that we really appreciate your hard work. I've had a mix of devices over the years but I've never used a better rom than this. I've also not had a dev push so many builds at a time 😄 therefore I can only imagine the time and effort you've put into this. Thanks again. Please don't stop the good work and ignore rest of the bs.

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] joeyhuab:
The latest update is finally here. Hopefully, all previous issues have been resolved or at least remedied. We're now on Android 12L aka Android 12.1, a new framework has been put together to replace the Android 12.0 version as Google did too many changes and I wasn't able to merge 12.1 on top of 12.0

A lot of features we've added in 12.0 have been not been added in 12.1 to keep the stability of the ROM. If you visit The Evolver, you'll see the feature list has been cut in half, but the ROM should feel more stable now and have fewer crashes.

Since the ROM has included Gapps as mentioned in the op, it should be full. Only in vanilla roms you can choose if you want pico, full Gapps.

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Kamui_:
Hello all,

I think it's about time to move to a new ROM because I cannot deal anymore with the missing or delayed notifications in MIUI 12.5

I have a K20 pro premium (yeah a Chinese one) and I am about to unlock it and flash Evo X. May anyone give me some guidance on how to deploy everything in order + the needed TWRP and Magisk version + modules so my Bank apps and google services work properly? Of course I am willing to do a full wipe.

No need to be to extensive, I am familiar with most of the processes of unlocking, wiping, TWRP, flashing etc. Just the order and maybe the versions for TWRP and Magisk. I "let the flashing sport" for 2+ years now so I am a little rusty and out of the latest updates.

As for @joeyhuab no words to say. I see that your A11 and now A12 projects are huge success, so keep up the good work. And don't care about haters. All artists, actors, singers, composers etc. have their lovers and haters. Just make your art better for your supporters, forget the rest.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] pinky0r:
1. Unlock Bootloader

2. Flash Orangefox Recovery, boot to it

3. format data (not wipe, really format)

4. reboot to recovery

5. Set disable-dm-verify & disable-encryption in orangefox settings (repeat/ensure that before _every_ update-flash)

6. flash evo x + magisk

7. setup phone

8. enable magisk zygisk - add banking apps to deny list

9. add magisk module safetynet fix https://github.com/kdrag0n/safetynet-fix/releases

10. hide magisk app with its own feature

11. hide (the already hidden) magisk with airfrozen (is neccessary for some banking apps like DKB TAN2GO) https://github.com/hyongbai/AirFrozen/releases/

Hi! First of all, thank you for this wonderful ROM! Keep it up!

I would really like to install this ROM but I'm not sure how. My device is K20 Pro (China) with xiaomi.eu 12.5.6 stable ROM. What firmware should I flash before installing this ROM? Is it the Chinese firmware? The Global one? Or I don't need to 'cause I'm on stable rom? I'm just confused and really don't know.

I have been reading this thread for over a week now but I didn't find the answer for my question. That's why I decided to post it here now. Don't get mad at me, I'm really sorry for asking. I just want to be sure.

Again, thank you! ❤️✌️
