I’m sorry to hear about your problems with your fairphone.
But before posting such a scathing criticism please keep in mind that many users are very satisfied with their fairphones. Every smartphone model has faulty specimens but that doesn’t mean the design is junk.
About your problem with the screen activating on it’s own please take a look at this topic.
About your problem with the clocks: Could you please make a screenshot. I can’t really immagine what you are dealing with.
About the Operating System: I’m sorry but if you can’t handle android you shouldn’t have bought an android phone. I’m sure you have some friends who use android on their phones and you could have tested them before buying the fairphone. You can however install a custom launcher, there are even launchers out there that simulate other Operating Systems.
If any of your problems can’t be solved by the community please contact Support. As I hear they are very friendly and happy to help.
