CneApp (Connectivity Engine) Runs in the background as part of the System. Enables seamless hand-off between mobile data and Wi-Fi networks. Can also dynamically measure network performance to prioritize using the best one (I think that's part of "Intelligently select the best Wi-Fi" in settings). Probably worth keeping on; I noticed connection reliability getting worse when I disabled it. https://www.qualcomm.com/news/onq/2013/07/02/qualcomms-cne-bringing-smarts-3g4g-wi-fi-seamless-interworking https://programmersought.com/article/35091829299/
