Thanks for your job. The ROM is awesome and works perfectly, only one question, is there any way that slow motion camera works?

I see this ROM reports "cast" to be working, has anyone tried it out? Coutless pie roms have the same issue, i.e. non-working cast/Miracast function. When it connects to wireless display the phone will crash.

bug: manual choosing of mobile network not working, rom working very good, but camera pictures quality much worse than ported miui 9 nougat with gcam.

Does this support gcam with night sight and if so, some dowload link?

[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] -valvoline-:
On what website can we see changelog? Sorry im not much of a tech or forums reader :)

Camera quality fixed? Manual setting of mobile network? (for me this very important as i work close to border and phone automaticaly enters foreign network because better signal but with expensive roaming services. I cant manualy set mobile network., because of that im back on ported nougat. Otherwise yours rom very good, thanks for development and keep our phone alive.Ii love the little bugger serve me very well there are no 5 inch new phones with 16/9 display and capacity keys, i hate the ****ty new 19/9 standard with buttons onscreen and the fkin notches.

Can i install directly from other pie ROM, without clean install?
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] Granrage_VB:
Sure NO, it will break everything.
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] Granrage_VB:
On Official website, where you can see the build info and download the ROM.

Nothing to fix in camera quality, working good and you first person complaining about camera, if you don't like it, you always can install camera you like more..

Mostly the same as with camera.. I'm using this personally and everything is working good and no one complained about this stuff.
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] -valvoline-:
Thanks for answer. I see changes on pixel experience page. I tried camera miui 9 ported nougat 7 gcam and the pixel experience gcam the pictures better and sharper on the ported miui. Quality on back cam much better in ported miui on low light. Maybe is some setting in gcam i dont know, im not much tech expert :) As for manual search of mobile network maybe someone else try to manualy set network provider, on my phone manual was not working, when try to manualy connect to network it searches and finds networks, but when you select one it just goes back to previous screen and automatic mode, on stock miui ported miui and los manual conection works (as i said this is my big problem because i need occasionaly to manualy select network, but if person has no need for manual network selection no problem at all with that).

Thumbs up for the rom development, very very nice rom. If manual selection mobile network can be somehow fixed/enabled i definately would install and have it as my daily driver. Maybe you as developer have some advice or workaround for manual connecting.

One more question, is there a way to permanently disable/remove the fixed google search tab in the bottom of home screen? The only anooyance in the rom.

Thumbs up once again, cheers.
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] Granrage_VB:
Only by changing launcher, this Google search tab in the bottom of home screen is by default in Pixel Launcher, because this launcher was made by Google..

Battery performance?

Hi, I've noticed my battery lasts less since I installed this ROM. Am I supposed to install a particular kernel in order to make it last longer, or is it just my feeling? By the way, I'm coming from DotOS Oreo, and I was pretty happy with its battery performance. I haven't tried May 5th update, but I will today and update if battery lasts any longer. Thank you

How to enter twrp recovery without pc and adb? Volume up and power not booting in twrp after install PE. On pc with fastboot command works and boots recovery.
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] Granrage_VB:
You need to hold both Volume buttons (Up and Down) and Power button. In better way it should be like: You hold all the buttons and when Mi logo appears you need to release the Power button and still holding Volume buttons till you get into TWRP.

Hi,

I flashed the ROM and got it working after a lot of trial and error. (That was by no means a *clean* install)

I like the ROM a lot, but now I can't use my camera. No app can access it.

Does anyone have an idea how I might be able to fix this?

Please no reinstall :-/

/EDIT: I cleared cache&data, disabled gcam apk and restartet my phone 3 times in the process and now everything works ...

I ain't even mad.

It can be dirty flashed over 12-05-19 rom?
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] davidnw:
I updated my phone soon after you posted the update. It is very good, FM radio works, the camera is good.

The only thing odd thing I noticed is that the DevCheck app shows zero deep sleep time, even over night. I installed Naptime but there is no difference to deep sleep.

This does not seem to have a big effect on battery life - the battery indicator says 77% two days remaining.

Thanks again for you work, it is really appreciated.

Update

I installed the BatteryStats app to check waitlocks. Now it is being watched it is going in to deep sleep !!
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] shaman_:

Hi, I cant update via OTA, I recieved the alert about new version and download without problem, but when I push Install button the Redmi go to TWRP and NO happens nothing. I checked and says that was not possible to found the file in orther to intall. The reason is that can not mount partition Data. In effect I try to mount Data manually but is imposible. When you see show 0 as size for partitons Data and System. Then I was to repair the partirions without luck. Then I was changging the type from EXT4 to FAT and then return to EXT4 and I can now install via PC. But if I try again via OTA Everything was whit the same problem. What can I do to update via OTA without lost everything each time? Thanks in advance. Regardas!
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] davidnw:
I have had problems using TWRP so I switched to the newer Orangefox recovery.

https://xdaforums.com/redmi-4-prime/development/twrp-orangefox-recovery-project-t3857387

To avoid losing all your apps and data you can use the migrate app which copies and restores the apps. You need to have a rooted device, I used magisk.
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] monito1402:
davidnw, Thanks a lot for your help. Orangefox recovery works amazing! Now I can update via OTA without problems.

Just to say that if you have the same problem as I had, then in order to avoid data lost, please do not try to repare your partitions with TWRP as I said in my first post, because your data will be lost and you will need to install PixelE. since the begining. And be aware that it is no posible to install Orangefox recovery from TWRP, because you can't mount the partitions (Data, System, etc) so what did I do?

Well, I installed Orangefox recovery from my computer using a usb cable and ADB-Fastboot_r28.0.2

How to:

1. Make sure to create a backup in the external sdcard or copy it onto your computer

2. Do you have your backup ready?

3. shure do you have a backup in external media.?

4. ok. then please do not cry if not.

5. Put your Orangefox recovery zip file in the directory where you have ADB-Fastboot_r28.0.2 (In your PC)

5. Enable USB debugging on your device

6. You need to reboot you Redmi as Recovery mode (TWRP). (Vol - & Vol + & Power at same time)

7. Conect your Redmi to the PC with your USB cable.

8. Into TWRP on the device, select “Advanced”, “ADB Sideload”, then swipe to begin sideload.

9. On the host machine ( the PC) Using a command line window (CMD), sideload the package using this command:

.\adb sideload filename.zip

filename.zip is the neme of your Orangefox recovery file.

10. See how happens the installation . . .

11. The device will automatically reboot into OrangeFox recovery after installation (allow this to happen)

12. Then reboot to OS & update via OTA!!

13. Enjoy!

My divice is not rooted! And works!

ADB/Fastboot Download the Windows zip from Google.

On screen nav buttons

Hello. The nav buttons at the bottom of my phone are busted so I enabled the on screen nav bar from Settings > Buttons. The buttons then appear at the bottom of the screen but does not respond to touch.

---------- Post added at 04:00 PM ---------- Previous post was at 03:16 PM ----------

I have additional info to add. On screen buttons only work if the notification shade (the one with toggles for wifi, bluetooth, torch, etc) is visible.

Seems to me this may be an issue related to z-index where touches are only correctly routed to the on screen keys when the shade has active focus.

The fingerprint unlock works for me. So it is not a general problem with the rom. No one else has reported the problem

Try removing and resetting the fingerprint. Try deleting the cache. Reboot several times.

As last resort try a clean install.

Which kernel is this?
[Xiaomi Redmi 4 Prime ROMs, Kernels, Recoveries, & ] davidnw:
If the question is to me, I just use the standard LinageOS kernel. I have not installed other kernels.

The difference I have observed between the Interactive and Conservative CPU governors is that the Conservative one keeps the CPUs at the minimum speed until more demand requires a faster speed.

Also I believe you can change the CPU governor using ADB via a PC without rooting your phone. For example this article -
