I'm on Arrow OS (Android 10) Nov 8 build and I'm really amazed to see how smooth and stable the ROM is. Previously I was on PE+ and I was looking to switch to a ROM without GApps (as I prefer Pico GApps). But I was not able to find a ROM as smooth and stable as PE+ (not even EvoX or Syberia OS). After watching a lot of YouTube videos and reading a lot of reviews and feedbacks, I finally decided to try Arrow OS (I used it only once on my Mi A1 for a brief moment before switching to PE) along with Pico GApps. I must say, this ROM is way more smoother than PE+ and suits my need perfectly. I hate ROMs with tons of "useless" customizations. That is one of the main I always prefer GZOSP, PE, LOS over other ROMs. I am getting an excellent battery life on thiw ROM. I charged my device last night till 90% (and reset battery stat) and right now it's 22% and I already got 10 hours 30 minutes SOT (no gaming though). This is what exactly I was looking for so long. The only bug I have faced so far is with the stock messaging app. I do not get heads up notification when receiving messages. I made sure to turn on all the options on the app notification page. It's not a big deal though as I am planning to switch to Textra or maybe Microsoft SMS Organizer app.
