@fredldotme @StandUpMobile @domubpkm For two days I have been testing this fix on RC and I couldn´t be happier. The daily lockups have gone and the OnePlus 3T is as snappy and smooth like when UT was first installed. Multitasking isn´t a problem either. Only had one freeze, I guess it was just me pushing the device to the limit. Thanks a ton especially to @fredldotme for making me appreciate my device running UT again as it's supposed to.

@haimeh So I never actually had to add the route ... it seems the OTA17 fixed my issue (but no all issues). One other thing I did around the time, although don't think this has anything to do with was something I stumbled on while troubleshooting: /usr/share/ofono/scripts/set-context-property 0 Protocol IP Here are the route tables for 3G & 4G with WIFI on: (hope the formatting holds!): 3G & Wireless default 10.x.1.1 0.0.0.0 UG 600 0 0 wlan0 default 10.xx.xx.20x 0.0.0.0 UG 700 0 0 rmnet_data1 10.x.1.1 * 255.255.255.0 U 600 0 0 wlan0 10.xx.xx.20x * 255.255.255.255 UH 700 0 0 rmnet_data1 192.168.250.0 * 255.255.255.0 U 0 0 0 anbox0 4G & Wireless default 10.x.1.1 0.0.0.0 UG 600 0 0 wlan0 default 10.2xx.x6.2x5 0.0.0.0 UG 700 0 0 rmnet_data2 10.x.1.0 * 255.255.255.0 U 600 0 0 wlan0 10.2xx.x6.2x5 * 255.255.255.255 UH 700 0 0 rmnet_data2 192.168.250.0 * 255.255.255.0 U 0 0 0 anbox0 Not sure if rmnet_data1 and 2 are standard across all phones /connections. If not, you should be able to spot yours by tailing the logfile... Hope this helps! PS: to check if you are on OTA17: SystemSettings> About OS should have Ubuntu 16.04(OTA-17)

@oliv thanks, I will reinstall UT soon and give it a try

@standupmobile @damiam note that APN settings sticking via the GUI are indeed a problem: you can manually install updated ofono and ofono-scripts packages that help address that. Even then it takes a bit of fiddling to clear out, but note that after that MMS is reliable for photos in and out when wifi is OFF. Wifi ON still is a problem, but broader than the P3a. SMS is now 100% reliable thanks to fixes from @fredldotme https://forums.ubports.com/topic/6039/bounty-for-pixel-3a-halium-9-stability/18?_=1630188659271

@StandUpMobile All I know is it goes quick when it goes without warning. Sorry but can't help with the other info. You will need someone else for that, but think your assumptions are right.
