Thanks for the rom. On lockscreen, it always shows an alarm with 10 minutes later after current time. It always shows this even if there is no alarm set. Is there a solution?
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] shootomanUK:
I just replaced the screen on my note 4 but now this rom is no longer working properly, when waking the phone up with the power button I cannot swipe to unlock the device.

I think it's a driver issue and the rom doesn't include drivers for my replacement screen.

Does anybody know how to make it work ?

My screen info is:

LCD:

qcom,mdss_dsi_nt35532_fhd_video

TP:

[Vendor]Biel,[IC]FT3435,[FW]Ver8

Was working fine before screen replacement :/

Thanks

Another pretty big issue I'm having is with the compass in apps like Google maps. I've calibrated many times but it is completely unreliable (can even point to the opposite direction and thinks I'm moving backwards). Anyone know a way to fix this?
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] Samahd:
Same with me, flash a custom kernel it will solve your problem franco kernel would be fine
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] BlackWhale2108:
Disable Android setup application. You can find it using search option in settings. Two of them will show up. Disable the one with round Arrow. Or both of them, doesn't matter. And then reboot your phone.

Download progress will start showing up.

I'm using latest build mixed up with Adreno 5xx GPU Driver v331 and Vulkan 1.1. For kernel i'm using Franco. It's really good for daily use also for gaming. Since Pie not as good as Oreo in heavy multitasking but LKT Magisk Module seems fix this issue. And again, your rom still the best for me. Thanks

[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] danny3458:
I can't understand how the roaming stupid bug could not be fixed in this update. This is absolutelly stupid!!!

Once you've got a different mobile network than your sim mobile network, you can not disable it until you phisically remove the sim card from your phone. This bug was reported in the previous version (6.3) and it's present in this one either.

Is that hard to fix this stupid bug? It's a pitty, becouse this ROM is ok, but this is a MAJOR bug and it's making this rom unfunctional for some people... I can use the "phone" now only as a tablet...

If is that the case... just write in the description that this rom is for mido PHONE if you are not using the roaming service and for "TABLET" mido if you are using the roaming service.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] Notorted020:
Try resetting network settings.. once and chck whether it worked or not...
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] danny3458:
I've tried that with no result. The point is that my sim card network is displayed on the top bar but I've got an "R" on the signal icon.

When I try to manually change the network (I belive this also should reset the network) I can find the sim card network but it will keep the roaming network anyway after selecting the sim card network.

It's like... it doesen't know how to exit the roaming service (the roaming network) once the signal of the sim card network is strong enough, not even when you choose to manually select the sim card network. The changes that the roaming network are making on some cache files or whatever... can't be deleted until you phisically remove the sim card. If resetting it's possible when you remove the sim card, than THE SAME "code" or option should be implemented when you manually try to change the mobile network. That's why I belive it's a stupid bug.

I also belive that this is the programming issue or the problem, or the annoying bug.

P.S.

I can't test any other method, becouse I allready choosed to remove and insert the sim card back to get rid of that mobile network.

After installng google phone, unable to set that as default phone. When I disable the AOSP phone, it gets set as default but on opening it the system soft reboots everytime. (Pico gapps)

Alternatively when I install it with aroma gapps, only one out of 3 attempts of clean flash makes it set as default phone.

Aex 6.4
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] mmedei9:
Use app systemizer (magisk) to make it a system app then set as default. Working for me on all AEX releases I have tried it on
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] BlackWhale2108:
Try to flash a gapps package which have google dialer included and then uninstall all the other system (google) apps that you don't need.

Or try installing Google dialer framework magisk module.

I was wondering if I flash a custom kernel, just to try and test it out, and then I want the stock kernel back, How can I do that? Is clean flashing the ROM only way to get the stock kernel back?

U can get back custom kernel by flashing boot.img of Rom.. u can find it by extracting the Rom zip.. no clean flash needed

[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] DepeTT:
Has been said many times, the wakeup delay is back because the developer removed the wakeup patch because it was causing a massive battery drain, it was written clearly in the changelog.

[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] BlackWhale2108:
In which partition do I flash the boot.img file?

Boot or recovery?

(btw, I am not flashing the twrp recovery file, I selected it just for the sake of screenshots, I am still asking for the boot.img)
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] litu93180:

[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] AmixTV:
Try a clean flash
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] BlackWhale2108:
So, boot partition, right?

And if I wanted to flash a custom recovery.img then, should it be in recovery partition or system Image partition?

Can someone tell me what this "10169" is and whyy it is using so much data?
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] litu93180:
for recovery recovey partiotion yes...
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] layman22:
Usually that icon and a number is assigned to an app that was uninstalled within the last charging cycle. Fully charging the phone and starting a new cycle should remove that from the battery usage panel.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] Techwicky97:
I Have the same issue. Screen freezes after screen lock. Tried Aosp and PE both doesn't work. And then Havoc worked fine. Then it should be the problem with display driver. I have also replaced my broken screen from AliExpress like you.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] alxdn:
Make a full wipe (system, data, cache, dalvik)

Clean Flash! Flash AEX Package.

Before these actions, make a backup and move it to a computer disk. You will lose all data on your phone.

[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] BlackWhale2108:
Just wiping system, data, cache and dalvik will not result in loss of any data.

Wiping internal storage (like in performing factory reset) will result in loss of data

Clean flash never results in loss of data.

But nevertheless, it's still a good idea to have a backup in case of an unexpected catastrophe.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] DepeTT:
It's the data usage panel, not the battery usage. Probably it's an uninstalled app anyway, even if normally it should say "removed app".
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] BlackWhale2108:
Search for this app in the settings search bar.

If it shows up, you can delete it. (if it's not a system app)

If an app is deleted, it should say 'removed apps and users'
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] ProfessionalNoob:
I searched for it in settings and i got no results :confused:
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] BlackWhale2108:
Then disable the data usage of that app from there itself, if that's bothering you.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] jijoejoe123:
i also had this with miracle droid oreo.. I found a way to solve this.. Disable double tap to wake screen option.. I didnt face that after this
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] anuragm13:
For ur information, a nandroid backup (or usually any backup) is stored in the "internal storage" and it is not wiped until u explicitly choose to wipe "internal storage" in twrp.

So one won't lose all data on the phone while clean flashing (wiping system, data, cache).

Only the ROM, apps and their data will be wiped.

But u can always move it to a comp. for extra precautions.

As per my experience, wiping the "data" partition does cause data loss, that too, a significant amount of data loss.

As soon as u wipe data partition, all ROM settings are reset to deafult (u will hv to re-setup ur device as u did while flashing the ROM for first time or as u hv to do with a brand new phone)

Also, u lose *ALL* of the user apps including *ALL* app data.

*ALL* text messages (SMS), contacts, call logs are deleted.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] alxdn:
Thanks for clarifying. I have not accurately formulated. Meant that it is desirable to make a wiping "Vendor" and "Infernal Storage".

I also had problems with the display of the alarm time. Decided to install the firmware clean.

Отправлено с моего Redmi Note 4 через Tapatalk
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] BlackWhale2108:
Yes, of course, a wipe of data partition will cause 'that' kind of data loss.

But I guess that the person who suggested to make a backup because clean flashing will result in 'data' loss, was talking about music, photos, videos etc, which obviously will not be lost unless, as you said, internal storage is wiped.

It still doesn't makes sense to clean flashing a ROM and then restoring a nandroid backup, it will get you back to the square one.

But restoring a backup of apps, app data, call logs, messages etc made by swift backup or titanium backup (I guess) does makes sense.

Hello, I have a weird problem with this ROM. Sometimes (2 times so far in about a month) alarm clock doesn't work. After alarm time nothing happens, but if I unlock the phone then suddenly the alarm goes off, e.g. 15 minutes later than it should.

I use AVG Xtreme alarm clock app. I used the same app (including the exact same version of that app) on MIUI for years before and never had this problem. Do you have any ideas how to fix this? I'm on AEX v6.3 (stock kernel), do you know if it's fixed in 6.4?

[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] Atexor:
I am still facing with the problem, that I can't increase or lower volume on my earphones using buttons on the earphone's remote while listening music on Spotify/YouTube, hovewer I can pause music it with middle button. These buttons normally works. Can someone confirm this isusue on latest version of the ROM?

It is really uncomfortable, i.e. to lower the volume while having a phone in your pocket.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] BlackWhale2108:
You can put your phone to do not disturb, but then you will not receive any notifications.

You can reduce the vibration strength to zero in advanced control, but then you will lose all kind of vibrations.

So, I guess the answer is no.?*♂️
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] anuragm13:
Yeah, i agree

PS..I think Migrate does the app+data backup and restore job perfectly when clean flashing or switching ROMs

That's not supposed to happen [emoji28]
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] ProfessionalNoob:
Vibrating only when i pick up the phone and ambient display turns on, even when i have no notifications
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] Sivakanthsharma:
My understanding is that you use a third party app for alarms. It might be getting frozen when the phone is in sleep. Try excluding it from battery optimisation.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] ProfessionalNoob:
No i don't even use alarms. I use the default clock app

That is THE problem.

I use that module too.

Before that module was installed, there were no vibrations whatsoever.

I don't think you can turn off those vibrations. I guess after a certain time you just stop noticing the vibrations.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] Papaj2137:
Yes, I forgot to mention this, sorry. I disabled battery optimization for this app and also gave it access to "do not disturb" as it requested. The weird thing is, the alarm clock worked fine today. It's like the system sometimes randomly enters some kind of deep sleep, where apps can't run.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] guchito9:

As far as I remember I noticed it before flashing kernel (I just wanted faster wake-up on fingerprint). And I can't find on kernel thread that someone has these problems except one example, but other person said that for him it works. So I don't know what is causing that.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] guchito9:
Why don't you just try it? Mine are working with Englezos kernel but no with Ethereal.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] Atexor:
Reflashed to Englezos. Fingerprints don't work anymore - I can't even add them again. I have error "Can't register fingeprint". To be honest I had problems on the latest, vanilla AOSPExtended (without magisk, custom kernels etc.) to make them working (1, 2). I am not sure whether that kernel caused me gone back to square one... the starting point.

Dirty flash the same version of ROM to back to default kernel didn't help. But once I flashed Ethereal - fingerprints works again. I think working fingeprints is more thing important than buttons on earphones hovewer it would be great to see FP fixed in the system by default instead of installing custom kernels to get it to work.

edit: previously added fingerprints work but when I want to add new (I deleted one before) I can't because error "Can't register fingerprint" again appears.
[Xiaomi Redmi Note 4 [Snapdragon] ROMs, Kernels, Re] guchito9:
Lots of people have fingerprint errors with this rom, I never experienced them, maybe something related to the actual sensor in the device. But you could at least try if the volume buttons were working?
