I just attempted a screen repair (on an s8 plus) with 2 different OEM screens, in the frame, brand-new. Neither one is getting an image. And neither was the original screen but it was cracked pretty badly. With this "black screen of death" issue, I'm wondering if the S8s have a really sensitive screen component on the motherboard.

So far I've had this happen twice with customer repairs. I'm still trying to figure out what the issue is but my suspicion is that it's similar to what happened with a few LG G4 repairs--that the new frame itself is causing the poor signal. On the G4 I was able to swap between screen+frame assemblies and go from good to a poor signal, even though I could spot not difference between them, at least as far as the spots on the frame where the motherboard made contact with the frame are concerned--the frame with the poor signal was noticeably thicker.

After having an issue with an iPhone 7's home button not working (but the touchID on the replacement screen WAS working, strangely enough) yesterday, I was being rather cautious with an iPhone 7 today. I used a heat gun to heat up the back of the phone (low heat to the point of the metal just getting "warm") and a slight bit of heat on the edges of the screen, avoiding the home button. I used a razor blade to slide under the edges of the screen, no more than 1/8" in. I didn't disconnect ANYTHING, but when I turned the phone back on to test, neither the home button nor touchID worked any longer. Again, aside from merely lifting the screen off the metal frame, this is the untouched original screen and home button I'm talking about. Also, I thought it might have been my imagination but I could've sworn while I was heating the back (and the phone was off) I felt the haptic feedback engine vibrate, like the home button had been touched. Update 15 minutes later: both touchID and the home button work on the...

Do you really have to completely tear down the device to replace the screen? Seems like the locations of the connectors wouldn’t necessarily require you to take out the motherboard if you’re just going to be pulling the screen off of the frame, but it’s hard to tell from this tear-down.

Just replaced my first iphone 8 plus screen. Yes, it is as it looks: it’s pretty much identical to the 7 plus. However, the one thing that almost tripped me up was that what I thought was the battery connector was NOT the battery connector. Make sure you actually disconnect the battery, otherwise you might not get an image or may do some damage during your repair.

Why don’t you guys start selling heat tables too so you can tell us at what temperature the adhesive starts to melt?

Is there something on the motherboard that could be damaged that would stop the volume buttons from working? Got a customer's phone where their volume buttons don't work post screen replacement. Just tried replacing the volume button flex but no luck. They applied a software update but haven't tried a factory reset yet.

Funny to see all these (obviously non LG) users complain about the "difficulties" of using a rear-panel-located button. Here's a simple trick that might make you feel stupid: step 1) with your right hand holding the phone, place your index finger on the rear edge of the phone (the left side if the screen is facing your--the side the fingerprint reader is closest to); step 2) slide your finger until you feel the fingerprint sensor. VOILA!! No need to smudge up your camera.
