Hello,

I don't know if it was already reported, but I have some bugs in this version :

- Privacy guard not working : it's not showing up in the Security & location menu.

I can look for it in settings, but i got the message : "LineageOS Settings has stopped" when I tried to launch it

- Developer options : reboot avanced is missing (same bug as privacy guard), root options are missing

- ADB : work but is disabled itself after reboot

Thank you for your work

Calls and Bluetooth

Has anyone else the problem, that calls are not possible via Bluetooth? Audio always automatically switches back from Bluetooth to Phone. This only occurs with calls - media audio via bluetooth is ok ..
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] Mister Advance:
If i was all you, i would take the bugs for what they are right now.

The developer already has stated to work on a new version, that probably will be added as a official lineageOS!!!

Also there will be an other kernel in the rom then the one used now....

So your reported bugs will probably something of the past and will be non existing in the new release!

IT WILL BE POSTED WHEN IT'S DONE! NO ETA, NO ESTIMATE IS AVAILIBLE ATM :)

Hi,

1. Does this ROM implement Glove Mode (high sensitivity of the touch panel)? I miss this feature in the original MIUI for 4x.

2. Does the IR blaster work?

Greeting and thanks for porting it to Redmi 4x!

[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] bvansambeek:
Thanks to the maker of this ROM and the support others are giving.

I have been using 15.1 for 2 weeks and my review is:

I like the ROM over MIUI 9 that was on the device from the start and updates after that. (V9.2.4.0).

The clean android and settings gives me a more in control feeling, compared to energie and data saving helping apps inside the MIUI.

However the battery usage was unacceptable for me.

With MIUI I normally had 40% left at day 2 and with this ROM I had 40% left at the end of the day...

I really like the big 4100mAh battery in the Redmi 4X and the feeling of long battery life (low degradation over the years) with only 1 charging cycle per 2 days.

Hopefully this will improve in the future.

I switched back for now to MIUI V9.2.5.0

(just a tip for others: the loading screen can take some time (5-15 min) after installing a rom. However you should be seeing android at the bottom of the screen with 3 loading dots)

I installed that rom with TWRP on my Xiaomi Redmi 4x global version (unlocked and rooted). The install went well and had no errors during flash.

Same problem here. Seems to be GApps related, tried Nitrogen and AEX with versions of GApps back to 20180314.

Edit: RR build 20180211 is working with current GApps.

Maybe it has to do something with this from the log:

!!! WARNING !!! - Duplicate files were found between your ROM and this GApps

package. This is likely due to your ROM's dev including Google proprietary

files in the ROM. The duplicate files are shown in the log portion below.

# Begin GApps <> ROM Duplicate File List

[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] joha386:
Keep it in english please. With the error log above, try to flash the ROM, than delete those files above via TWRP ( advanced - file manager ... Or somewhere in the TWRP, I don't exactly recall ) and afterwards flash gapps. Might be worth a try.

Had the same problem btw. After the Los logo was doing its thing for about 30min on the first boot I hold the power button for a hard reboot. The reboot worked and everything was as it should be.
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] OG79:

I Wonder why the old RR build ist working. The log from the old build only says

U can't login to a wifi using eap Sim authentification

U can't send or receive MMS without enabling Data on your sim (wich i usualy don't as i only have 50Mo of data ...)

The MMS issue is a big problem to me ... Is there any way to solve this? (By the way, i encoutered this MMS issue on all AOSP rom i tried so far but it works just fine on MIUI rom)

I'm thinking on buying a brand new Redmi 4x, and I would like to ask if this rom is ok for the phone to be used as my main daily phone.

Thank you.
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] appofox:
I'm using it for 4 months now and very happy. Settings app sometimes crashes while in apps menu, but I rarely use it. There are no VoLTE and looks like bluetooth audio glitches, but I don't use it at all. You can find more info on these in this forum - just search.
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] Bidibu:
Ok, seems good, but I have some more questions:

- do you think that LineageOS 14.1 should be a better choice instead of 15.1, as I will use bluetooth audio massively as in-car music player....?

- just to be sure, I'm downloading gapps, I choosed ARM64 --> 8.1 --> pico (I want just play store, maybe can install extra apps later from it), am I on the right choice?

- Does "no VoLTE " means thet I will not be able to make/receive calls when in 4g mode? Or just that my calls will not be on HDAudio, but just "normal" calls?

Thank you again.
[Xiaomi Redmi 4X ROMs, Kernels, Recoveries, & Other] appofox:
- I don't know how 14.1 works with bluetooth services. Never tested, never red, never needed. So I can't compare these two ROM versions at this criteria. Try to search by yourself.

- At that time I've used Open Ggapps arm64 8.1 Pico Unofficial dated 20171215. Installed every other gapp on my own demand. Never updated gapps itself though.

- In my case if I choose "Preferred network type" LTE only - I can't send or receive calls. If I choose "Preferred network type" LTE alongside with other standards, I can send or receive calls - at call time phone just falls-back to 3G or other standard you chose. This option disrupts data connection at call time though - avoiding this in my opinion is the main VoLTE purpose. After all I chose 3G only - data speed is more than enough for me and I do not loose battery juice while phone is constantly reconnecting between preferred network types. You should consider fall-back to 2G if you frequently find yourself in forest or basement etc.
