yes, there are options for Linux-based cell phones, but the problem is that many launched them when many did not feel they were necessary when Android and iPhone were still very convenient to use, causing many projects to go bankrupt. currently, those who try to do something like this are holla phone, BraX3, another Spanish cell phone but I don't know if it still exists, Ubuntu touch, harmonyOS, cell phones that can be built with Rastberry and Up Phone, but I don't know if the latter is based on Android it can be compromised.
