| Component | Comment |
|---|---|
| Camera | √× (Cameras work, but front camera pops up on first boot and won't retract, requiring manual control via terminal command - see #539 and below note 1); Stock carema apk only support main camera as 12MP |
| Audio | √× (No Type-C audio - see #542; Background noise with armature earphone at low sound level - see below note 2) |
| Bluetooth | √× (In-call audio doesn't work) |
| Display | √× (Auto-brightness doesn't work yet - waiting on the overlay to be merged; Corners look slightly pixelated due to lack of corresponding overlay item) |
| WiFi / Hotspot | √ |
| GPS | √ |
| SIM / Mobile Data / Voice | √ |
| VoLTE | ? (Untested) |
| Fingerprint | √× (Recognition a little slower maybe due to system setting; Unlocking from off/AOD state not supported, need press power button first) |
| NFC | √? (Support card info reading via NXP.TagInfo, need more tests like card writing / simulation) |
| Offline Charging | × |
Terminal command for manually controlling the front camera motor (may require su depending on the GSI):
Popup: xiaomi-motor popup 1
Retract: xiaomi-motor takeback 1
Maybe it's just a problem caused by vendor, or lack some configure in gsi system.
If you have a high-sensitive armature earphone and suffer from terrible background noise, try to use CLS_H_ULP rather than LOHIFI as headphone default mode in /vendor/etc/mixer_paths_tavil.xml file.
The original string is "CLS_H_LOHIFI".
<!-- Headphone Default mode - uLP -->
<ctl value="CLS_H_ULP" name="RX HPH Mode"/>
<path name="hph-lowpower-mode">
<ctl value="CLS_H_ULP" name="RX HPH Mode"/>
</path>
