Chosen Solution

so i replaced the battery, speaker and front camera/proximity sensor and now my phone is acting crazy. It randomly shuts down, no vibration, no sound, no wifi, and cant hear anyone when i call. What did i do?I followed the guides and was as careful as i would be with a clients machine. I work at a computer repair shop so this is kind of embarrassing…. Luckily i knew enough to test it before i put it all back together.

Did you have to pry the battery out?

Did you try putting the original components back in the phone? Why did you replace the front camera assembly? Does this phone show any sings of previous damage? Do the volume buttons work?
