The current release is always attached to the OP of the module support thread. Usually versions from Urnyx05, Arnova8G2, and Wichaya work well on these devices. GCam 8.1 from BSG should work (either _ruler or _scan3d packages). You should check BSG page as newer versions may might be available. GCam 8.1 from BSG also works (either _ruler or _scan3d packages). Reports in January 2023 say that LMC 8.4 and BSG 8.1 work on this phone. Both versions support configs, so follow the link to the configs on each download page to see if there’s a config for this phone.
Another reason why people seek custom ROMs is because of the extra features they offer. They also reduce bloatware that comes as a part of many manufacturer skins. While there are many custom ROMs out there, not all of them are stable enough to be used as your daily driver. The first fruit of Poco’s labors, the F1, was announced and positively received a couple of months ago. A kitchen-sink flagship this isn’t, but the correct corners were cut to reach the very affordable $300 price. The Poco F1 is blazing fast and lasts forever on a charge — two very important features in any smartphone.
