Not great, not terrible. The android support is hit and miss and the official store is mostly full of junk. Their SDK is rudimentary and there is close to no documentation. After they signed a deal with the russian state I gave up on them. I am on Plasma now which has an overall better experience.
Do you use Plasma on a phone or tablet? If phone, can you say which hardware platform and how "well" it works as an actual phone, making calls, texting, etc?
Are you saying that Plasma Mobile runs on any device that is supported by libhybris?
I was asking about Plasma Mobile ( https://plasma-mobile.org/get/ ) that the parent mentioned switching to and I wasn't aware that libhybris is a requirement.
If you want a plasma mobile device, your best option is to find devices that are supported by PostmarketOS. That is a distro (kind of like Ubuntu etc ...), which under the hood can use libhybris to talk to Android drivers etc..
