If you are in town for Android 5.0 Lollipop ROM today, not when Samsung updates their software, grab the latest CM12 ROM beta by XDA user Temasek, available for T-Mobile Note 3 SM-N900T, SM-N9005, Canadian SM-N900W8, and Sprint SM-N900P.
This is a “beta” version which has pretty much everything working except video recording and NFC. I have been testing it as daily driver for last couple days and have to say the battery life and performance is excellent.
As for benchmarking performance, it didn’t do as well as the CM12 ROM I tested on a Galaxy S5 couple days back but it does better than stock TouchWiz Note 3. Apart from benchmarks, performance is outstanding, UI is superfluid and fast as you would expect from the latest Android 5.0 Lollipop.
Overall, CM12 ROM beta is probably not recommended as daily driver (unless you can live with broken video recording and NFC) but you can always make a backup ROM, try Lollipop, then restore your ROM back. So, definitely give this guy a test drive this week(end) and do let me know what you think!
