I've been using LineageOS for on a XQ-BC62 a week now and it's good!
Broken stock, broken in LineageOs:
- 5G crippled in MBN files
- VoWiFi on T-Mobile
- USB 3 data unstable (probably chipset)
Broken in LineageOs, works stock:
- Google Wallet (Google's fault)
- Two-level notification LED (dim color for charge state + brighter blink for notifications)
- Notification LED and lock screen notification brightness don't follow ambient light
- MicroSD card shows corrupted after using it in a computer
Fixed in LineageOs, broken stock:
- LTE/5G indicator
- Screen brightness following ambient light
- Lock screen notification content
- Fingerprint, touchscreen, and UX stability while phone is in hand
