Phone keeps crashing after repair job.
Hey guys, I did a bit of a rehaul on my iPhone 4s last weekend. All parts I bought were from iFixit.
- I replaced the battery, which I bought brand new.
- I replaced the volume buttons, which I bought used.
- I replaced the vibrator, which I bought used.
Everything seemed to go off without a hitch. I wore latex gloves so I didn't have to worry about finger oils creating interference, I put all the screws and parts on a white paper towel so I wouldn't lose any, and I watched Youtube videos to accompany the iFixit guides.
Putting it all back together, the only thing that still seems busted is the volume button (I have to replace the entire headphone jack cable), but that's not the issue.
After putting everything back together, my phone has been crashing left and right. It'll freeze when switching apps, it'll crash in the middle of an app, sometimes it'll automatically shut down when I let it idle, when leaving my apartment with the phone in my pocket sometimes it'll shut down, etc.
I have tried a hard reset, restored factory settings, recovered from back up (I backed the device up on my iTunes before I took it apart), and set it up as a new iPhone. Currently my operating system is iOS 7.1.1. I have not made the switch to iOS 9 and I would like to avoid it if I can (though I know with iOS 10 announced I'll have to make the jump eventually if I want to keep using this phone as long as I possibly can. My goal is to make it to 2020, haha).
Does anyone have any ideas as to what may be causing these crashes and if there's anything I can do to get it back to normal? I've tried restoring factory settings a few times now, though I only restored from my iTunes backup once and set this up as a new iPhone device twice. I do have a backup on the Cloud that I did back in January I can try. Otherwise, I might have to upgrade to iOS 9 and see if it's a firmware issue.
The only other thing that could possibly be behind it is when the replaced volume buttons didn't fix the issue (volume increase won't work) I had jury-rigged it with a small piece of a business card between the button and the sensor. I really doubt that foreign contaminant would be the cause of my crashing, but I also want to be up front with everything I did to the device.
If anyone has any ideas or has encountered similar issues, I'd love to hear what you have to say! Thanks!
Is this a good question?
