Use Nova, trebuchet doesn't really work well in my opinion
[Lenovo K6 / K6 Power / K6 Note ROMs, Kernels, Reco] inf_dragonfly:
I am using April build. It works amazing. Battery lasts far more longer than stock nougat. No bugs. Not much a customization tho. If you want root download and flash from lineage's website. Thanks to developer!::good::)

(If it comes with Nova instead of Trebuchet it will be better but not a big deal.)

GApps

I have used mini, stock and Aroma arm64 opengapps with clean flash. All 3 opengapps works fine without major issues. There are minor issues related to opengapps such as sudden change in playstore UI (which looks like junkie or 18th century), lessening of maximum speaker sound, change in vibration (intensity of vibration is high). So I tried MindTheGApps arm64, all problems fixed, except I lost facelock in smartlock.

---------- Post added at 08:56 AM ---------- Previous post was at 08:48 AM ----------

Trebuchet problem is not fixed in both OpenGApps and MindTheGApps arm64. But Pixel launcher from OpenGApps Aroma arm64 works perfectly and so smoothly when replaced for Trebuchet.

---------- Post added at 09:07 AM ---------- Previous post was at 08:56 AM ----------

I faced more minor problems when using any OpenGApps arm64. Especially when Google services got updated, there was change in playstore UI which was fixed after cleaning playstore app data and cache with 3 restarts.

Can we not switch :confused: the data SIM to 4G, without putting the sim in Slot 1, as it was possible in stock?

Like I want to switch from Jio 4G to Airtel 4G, and on switching Mobile Data for Airtel, it only turns up 2G, even though LTE is enabled in optional, or no network when in LTE Only Mode. 4G works when manually swapping the sims, but eh, could you look out for a fix?

Are you using lOS 15.1?

Hey! I did not face this issue in 14.1, and even I had Jio in SIM 2. The problem is not about Which sim is using 4G, the issue is about switching data SIM actively, as in stock and los 14.1.
[Lenovo K6 / K6 Power / K6 Note ROMs, Kernels, Reco] Deaddbear:
You can only select 4G on one sim at a time. So if you want 4G on Airtel, then you have to set Jio sim to GSM Only and Airtel sim to GSM/WCDMA/LTE. Note that when you do this your Jio won't work since it is a 4G only network. If you want to use Jio 4G again, then do the vice versa, set Airtel sim to GSM Only and Jio sim to GSM/WCDMA/LTE. Also be sure to select the proper network for mobile data. This is not a bug in the ROM. It was just an additional feature added by Lenovo to the stock ROM.
