I've a combined fingerprint reader and power button. The reader went first and now the button only works if I can get my thumbnail into a certain spot to really depress it. Camera app crashes immediately so I take pictures through snapchat or the Messages camera. The Camera app would probably be fixt if I reinstalled my ROM but thats an hours long process between backup, downloading everything, and setting everything back up. I'll get around to it.
Phones and cars suck enough, hooray for cheap apartments! Something like 70% of millennials regret buying a house so you're in good company.
