The iPhone 6 has been broken for more than a year. I didn't get the chance to fix it or I didn't feel compelled to fix it until just a few days ago.
There are no shortage of information out there teaching you how to fix the screen or whatever that ails your phone.
I think the number one most often fix is the screen. By screen it means the front facing glass or the top shell. As the top shell is more than just a piece of glass. Although as a consumer and when you talk to the repair shop, you'd like to say it's just a shattered screen of glass as if . . . . No, it's not just a piece of glass.
I was going to spend from $15 to $70 just for the top shell. The takeaway is you got what you paid for and fortunately there are some good parts out there just as there are some that deviate quite substantially from Apple's specifications. You just have to manage your expectation accordingly hoping that the vendor gives the right information. If the vendor is selling an aftermarket part at $15, an aftermarket premium at $20 and an OEM part for $50 for example, you better believe the aftermarket $15 is just passable, the color maybe off, the touch response is not so great and the shell can barely put back in.
In the end, I got something like $31 for the shell glass and digitizer included it's rated S+, the vendor's way of saying very very good; I have to transfer the small little parts from the broken shell to the new one, mainly the fingerprint biometric home button at the bottom, the little front camera, proximity sensor ... Buying just the glass is cheaper but then you have to really clean up the shattered shards of glass from the old one before you have to glue the new one back on. Most of the video I watched didn't take that route. So to recap, you have about three options, just change the glass; change with a new assembly but transfer old small parts from old shell; or buy a full assembly including small parts. Note that the old original biometric home button works only with that phone any new home button won't do the fingerprint authentication--that's why you need to transfer the home button from the old to the new if you want fingerprint authentication to work. Any new non original home button you bought would only act as home button but can't do the fingerprint biometrics authentication.
Having the right tools is crucial. I can't tell you how many times I stripped the screws before I bit the bullet and bought something just a bit better.
With presbyopia it's very hard for me to see and handle those 00 Philips screws and ribbon connectors.
It took me two goes of take apart and put back together to get everything work. The first time the headphone jack was not working. Then later I found out neither was the earpiece at the top of the shell, that's no sound coming out. I you Google that, you will find all the usual so called fix, clean the lint and dirt out of that headphone jack which didn't help in my case, or use an original Apple headphone. Or worse case scenario, buy the headphone jack replacement which would have set me back at least another week or so. I decided it's probably some bad connection, it's just a blind faith on the parts and no faith on my eyesight and assembly skill. I tend to blame myself if something doesn't work.
My hunch was right. The second time around the headphone jack works and so is the earpiece at the top.
The battery removal was a pain. The glue was super strong.
All said and done, I waited for three days and spent close to $60 for parts: top assembly, new battery, and two sticky strips. If a repair shop asked for $100 or less for the same repair, just give the money to them.
