@anon87905765 You still haven’t told us what you tried already (unless opening the phone took you 3 days) or given us a lot of other information that helps us help you, like: What OS are you running?, or when do the reboots happen? E.g. do they happen in a specific Wifi?, when the phone runs hot?, while using specific apps (even in the background - e.g. Facebook)?, when the phone is put on the table?,…
This is a community forum, so here you get help from community members, who are not bound to a 2-year warranty, but are willing to take their time to help you for free no matter how old your phone is.
This is what we are here for and what we can offer. We are not here to listen to rants about things we can’t change.
So if you want our help, please post info we can use to help you in the #fairphone2help category (e.g. in this topic). If you just want to rant please do so elsewhere.
