[Xiaomi Mi 8 SE] No VoLTE on latest stable 9.0 firmware; bluetooth calling issue etc #398
Comments

Also if I flash the vanilla system.img directly from fastboot command line, the device will refuse to boot everything, booting directly into fastboot mode. But flash it from twrp will not cause the problem. |

VoLTE is device dependant, hence not included by default.
However it doesn't mean it's not supported.
You simply need to repackage your vendor's ims.apk and install it. (You can
find the repacker at
https://github.com/phhusson/apps_repacker_aosp/tree/pie/VoLTE-CAF )
I'm pretty sure there are some tutorials on the internet with pre-packaged
ims.apk, though I'm not aware of them.

Clean installation of latest pie based stable firmware

Flashed recovery "recovery-TWRP-3.2.3-1217-XIAOMI8SE-CN-wzsx150.img" (the
latest 1227 build can't boot)
Flashed boot.img (extracted from
https://sourceforge.net/projects/xiaomi-eu-multilang-miui-roms/files/xiaomi.eu/MIUI-STABLE-RELEASES/MIUIv10/xiaomi.eu_multi_MI8SE_V10.2.2.0.PEBCNXM_v10-9.zip/download
latest stable release)
Flashed AOSP 9.0 v110 arm64 a-only vanilla
Didn't mod anything or flash any other zip
Used for 24 hrs with dual SIM.
Issues found so far
-
VoLTE isn't working on either SIM (carrier offers TD-LTE VoLTE on both
SIM cards, this is supported in stock firmware; using GSM for now. Current
setting: SIM1 LTE/UMTS(PRL); SIM2 GSM(can't be changed))
-
*#*#4636#*#* can only show the information of the SIM card in the
first slot
-
After tapping "Preferred network type" in Settings -> Network &
Internet -> Mobile Network, the phone app crashed, the signal in status bar
disappeared for a second or so. This is default to WCDMA preferred, can
only be changed for the first SIM in *#*#4636#*#*
-
Calling audio can't be played on bluetooth headset (played on the
phone regardless of settings), media sound works fine

Stock system.img and vendor.img can be extracted from the link for latest
stock firmware.
Finally got rid of MIUI after waiting 360 hours, excited to find generic
GSI image worked out of box (mostly).
(Maybe other issue will emerge in a couple of days?)
A huge "thank you" for your great work! (from a noob)

Thanks alot for your info, build it by myself from the stock stable pie firmware. However the ims.apk is located in /system/priv-app. After changing that, the build script worked. Here's the result. However, imediately after installing the said apk, the signal lost, both SIM slots are showing as empty. |
|
Steps I've taken to build ims.apk:
|
|
"Preferred network type" works on stock Oreo vendor. On Oreo vendor, 3 options are available: LTE, 3G, 2G. Not so detailed as it is on pie. WCDMA preferred, GSM/TD-SCDMA/LTE and so on. |
|
Tried a prepackaged ims.apk found on the Internet, for Lenovo ZUK Z2. Just to try my luck, since these two phones are vastly different on spec. Any idea? Thanks in advance. |
|
Tried another ims.apk found on the Internet, with the same result as the previous one.
My conclusion: These ims.apk maybe compatible with previous Android versions, but not the current one. Need a working script to build a new apk. |
|
Video recording doesn't work in DND mode, taking photos works fine. |
|
This is what screws you over. You need to find the APK / jar which contains this class and slipstream it's smali code into your repacked ims.apk for your device's IMS implementation to work properly.

Same results for me on my sm-j600g, phone app crashes after installing ims apk. Unable to make or receive calls, volte not working. Any improvement ? |
|
Samsung IMS is not supported and is entirely a different issue.

1. Showing HD capable notification.
2. Able to call under LTE-only
3. Doesn't count the time after answering the call on another phone,
the call works after answering it.
4. "Hanging up" forever after tap the hangup button.
5. Video calling doesn't work.
6. No IPv6 address.
7. Still can't change the network type for second SIM card (not
accessible through #*#4636#*#, crash com.android.phone if change in
Settings app)
My conclusion: These ims.apk maybe compatible with previous Android
versions, but not the current one. Need a working script to build a new apk.
I've noticed that the build script seems outdated, with the wrong ims.apk
path.
Also I noticed there's an mysterious "imssettings" app in stock ROM, under
/system/app, what is this for?
Have you enabled VoLTE on your phone? Just curious. If yes, how?

Thanks! However I don't have enough knowledge on this, hopefully someone else can step in. |
Samsung and LG have nonstandard ims implementations, in which some libraries of ims.apk has been incorporated into the phone.apk of the stock rom, rather than resides in the vendor partition. |
Just dirty flashed v111 over v110, everything works like a charm! Updated to the latest version! |
|
@dkmgfk - "everything works like a charm" |
Sorry, forgot to mention that Bluetooth call still doesn't work in the latest gsi image. However, this issue and VoLTE are the only problems I've found in a month use. |
|
Good Morning from Germany ;) PixelExperience-Devices/device_oneplus_sdm845-common@977444a Have a nice day :) |
@dkmgfk Hi, did you mean VoLTE is working like a charm? Did you install any ims.apk afterwards? How exactly did you do it? |
|
Hi! Unfortunately none of the problems got fixed over the months. Bluetooth and VoLTE are still not working with latest image. Sorry for making bold statements. However it seems that these two problems are universally presented on devices with GSI ROM, eg. Mi8, Mi6X, PH-1 and a few others. VoLTE problem is device specific, and dualSIM settings still have some quirks in AOSP ROM. But they don't bother me too much since my carrier still provides optimal GSM signal here, and I don't use Bluetooth headsets heavily. |

New LR.team TWRP is out! Check out the new flashing guide for details. |

@phhusson Sorry to bother you again, (with all the notification emails), but could you validate this following statement I wrote on the device wiki page? "GSI images relies on the stock vendor partition to work properly. So stick to the GSI image with the same Android version as the MIUI." Thanks alot |
|
What?
No. You can run pie gsi on Oreo vendor.

Surely higher version system img can run with lower version vendor, but I encountered several more issues compared with using pie system with pie vendor |

Can't obtain IPv6 address on LTE. IPv6 on LTE can be obtained on stock firmware. Maybe related to the above issue.
