[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] articuno1_au:
For those of you running into the problem with not being able to unlock your phone after a restart because the enter key isn't there, it seems to be due to the "auto unlock on pin" setting that was present in Android 10 builds.

Two work arounds, either use a physical keyboard and just hit enter. Or enter your pin, backspace the last digit, then re-enter it and the phone will unlock.

I've run into another problem, I can't decrypt my data partition using the latest Orange Fox recovery after the update. I read back through the thread and saw some references to FDE but wasn't sure if it was related, so apologies if this is already covered. Any suggestions?

Clock widget does not work anymore, new Cam is very buggy and crashed all the time.

any advice ?

Battery life in latest build is not good. Lost about 18% overnight. Will check for one more day.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Anertz0153:
I've also had problems with the camera

We were able to fix it and here it is (as you know, portraits do not work)

From the Google Play Store

Install ANXCameraPro (free)

Open the app and enable ANX Global

Open the camera

Everything will be fine!

Hi, joeyhuab thank you very much for your work .
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] articuno1_au:
OK, so continuing my research, I don't think DFE is related. Is anyone else having trouble decrypting their data partition? Is anyone else running Orangefox?

I'm a bit stumped here. I can flash the updated rom to see if that fixes things, but it requires using USB_OTG as data is encrypted, so tomorrow job..
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] zakcng:
After this latest update I can't get mobile data working? Any ideas? Thanks a lot.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Davidkrch:
I had problems with data as well. I had to restore APN Settings to default then re-add my APN to get data. Also switching the Preferred network type to 2G and then back to 4G might have helped.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] StephCo:
Same as Davidkrch but just restored APN and instant 4G+ connected

Network & Internet - "Your Sim" - Access point (at the bottom) - "little tree dots top corner" -> Restore to default

hope this translation is understandable

Notification panel stucks on full screen games

Everything is working fine, android 11 is still in development but there is big issue when you play full screen games like PUBG Mobile or any game, the issue comes when you open the notification panel while playing games, notification panel get stuck on top, it won't hide, sometime its with dark background , same thing happens with navigation bar but nav bar hides when volume key is pressed, but the major issue is with notification panel, it doesn't go away unless you kill the app and restart it.

can you please resolve it quickly, i need evolution x for my daily gaming driver.:fingers-crossed:
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] jiyoohji:
I have an issue with notification bubbles. Whenever i use a custom launcher the notification bubble doesn't show on the homescreen. It only reappears when you're inside an app. Is there a fix on this?
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] joeyhuab:
Every Android 11 ROM has the same issue. If other developers were not able to fix it yet, what makes you think I can resolve it? And quickly as well as if I have all the time in the world. That said, install the fullscreen gestures module in Magisk and your issue will go away.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] joeyhuab:
The issue is with your launcher not allowing overlays on top of it, not the bubbles.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] jiyoohji:
Is that so? Is there a way to enable overlay on settings?

The AAC Bluetooth audio codec seems to work now, no stuttering. I'll continue testing to be sure.

Actually it is still present, just didn't happen for one session for some odd reason.

Setting LDAC bitrate, depth or sampling rate (developer settings) in the latest release causes headphones to disconnect. These settings always worked on older releases.

Enabling the status bar traffic indicator causes massive log spam.

Logs for both new issues are attached.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] P4Block:
Clean flashed and had that old bug where the phone would randomly stop being able to use mobile data / no 4g icon up top but it shows as connected. I saw that it was related to Android forgetting to use the APN in a changelog somewhere, so I went into the APN menu and just tapped the one. Data came back instantly.

Edit: i noticed when the thread link was posted on telegram group, it displays this message. Sorry about that sir Joey! :) 2/20

I am experiencing a huge chunk of almost 1GB used running RAM on both apps, Gboard and Google Play Services. I am trying to find the solution on these, I even did the clean flash by following the guide on Telegram Group. My modules are Energized Protection, Advanced Charging Module and AOSP Dialer with recorder. Just saying or if you guys experienced this, help me out but still im trying to find or doing the steps to resolve my problem lol, thanks

EDIT: this problem causes energized protection. i decided to remove and uninstall the energized protection right after i discovered the problem since december - 2/3/2021

Sadly to say yes. I also experienced the same situation as you are right now. It means that your RAM is now experiencing near fully usage. I did clean flash but same situation appeared dunno why, see my previous post on that. Right now, it seems fine i did clean flash once, google play services and Gboard isn't eating my RAM anymore lol, i dont know why but the only thing that i did is clear data of GBoard and tadaa my ram is now fine.

Hi mate,

APN & Mobile data work flawlessly on the latest build: EvolutionX_5.1_raphael-11-20201129-2037-OFFICIAL. No random System UI reboots anymore when switching from Wi-Fi to Mobile Data. VoWi-Fi calls work as well. Thanks for that.

The Fingerprint Icon Selection under The Evolver/FOD settings is a very nice addition. Can you please add the standard/minimalistic AOSP fingerprint icon to the list? The one that was the default option in the Nov 29 morning build? That icon is kind of already there, it's just that it's a bit too big.

Google Play System Update seems to find an update but it is unable to download and install it. Can you please look into this?

The guys from Pixel Experience seem to have found a fix for the crackling sounds when receiving a notification [https://xdaforums.com/showpost.php?p=83810185&postcount=2888]. Would you be able to port their fix to Evo X?

When the navigation pill is hidden, the bottom bar under the keyboard disappears which makes typing a little bit more difficult. I've tested this both with GBoard and with SwiftKey. Can you do some abracadabra which will prevent the bottom (relatively blank bar) from disappearing when the navigation pill is hidden?

Last and least, can you please add the Google Product Sans font to Headline / Body Fonts?

Thanks again for your hard work and dedication,

deilativ

[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] joeyhuab:
For now, that icon wouldn't be included as a different code is needed to make fingerprint selection work.

It's not a bug of the ROM. It's a Google-side issue that I cannot fix.

We use MIUI prebuilt vendor and not OSS vendor. That fix is only for the device tree they use and is not applicable for what I use.

The Hidden option for the pill is an overlay. It cannot be altered to make the space show with the bar hidden.

The option will return but will require root to be used.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] Peter the Great:
If you want the Google Product Sans headline right now (you need root), you can simply grab a copy of the font online (I will not share any files), then make backups of the /system/product/fonts/ArbutusSlab-Regular.ttf and /system/fonts/SourceSansPro*.ttf files (and move them somewhere else, like Documents), then take the Product Sans Regular font file, rename it exactly as ArbutusSlab-Regular.ttf and put it in the /system/product/fonts folder. Now go to the /system/fonts folder, you should already see lots of fonts there, including a family of Roboto fonts. Copy (

not cut

) those fonts and rename them to their SourceSansPro equivalents (the ones you backed up earlier. Some font styles are named differently, like Roboto-Medium and Medium-Italic will become SourceSansPro-SemiBold and SemiBoldItalic). Place these renamed Roboto font files in the /system/fonts directory (same place as original Roboto files as well). Change your font in Display settings to ArbutusSlab / SourceSansPro. Reboot. Enjoy!

Note: if you get a bootloop, it's because there are either typos, or extra, or missing files in the /system/fonts directory. The /system/product/fonts directory is allowed to have whatever you want in it, but not the /system/fonts directory. Make sure everything is exactly spelled, and that all files are present, and that there are no extra files, and no missing files. Use TWRP's file manager to copy and rename files to get back to a bootable state.

I just clean flashed the latest (EvolutionX_5.2_raphael-11-20201210-1143-OFFICIAL) ROM. I noticed a few problems:

1. The FOD icon dispalys on screen randomly when I am using the device. It disappears only after locking and unlocking the device.

2. After clean flashing, all the files on my internal storage got deleted. I did wipe before installation but even the ROM zip file is not there in the storage.

3. The biggest issue for me is that I can't connect to campus WiFi anymore. The configuration is PEAP/MSCHAPV2. Under CA certificates, we usually choose "Do not validate" but now CA certificates is set to "Use system certificates" and can't be changed. "Use system certificates" setting requires Domain name which I don't know and have never needed to use before in any ROM. See the screenshot.
[Redmi K20 Pro / Xiaomi Mi 9T Pro ROMs, Kernels, Re] joeyhuab:
