what's up YouTube I have a fantastically interesting video for you today if you are watching this you either have a deep love for technology guts or your phone is broken and you want me to show you how to fix it well you're in the right spot today I'm going to show you how to do a glass only iPhone repair with dry ice if you are subscribed to my channel already you are seriously the best type of human if you have not yet subscribed hit that subscribe button and buckle up we are going to jerry-rig all of the things so I have to cracked but completely functional iPhone screens in front of me that have already been removed from their phones the black one is an iPhone 6 and the white one is an iPhone 5 you can watch my previous videos for the screen removal process this particular video is just explaining the dry-ice glass removal I have paid about 5 bucks for this block of dry ice now iPhone screens are made up of a few different layers the important layers that you need to worry about is the top layer which is just glass under that you have the digitizer layer and the LCD both of these are fused together in one unit and is about as fragile as an eggshell you think I'm joking about the eggshell stuff but I'm not it is very fragile now normally when a tech does a glass only repair they either have super expensive refurbishing equipment or it is possible to use a heat gun to bring the phone up to 100 degrees Celsius to melt the glue between the top layer and the LCD layer it is a difficult and painstaking process now I was on the phone with tech MD another YouTube channel about a week ago and we are talking about the new liquid nitrogen machines that can freeze off the glass these liquid nitrogen machines can get down to about negative 140 degrees Celsius which is incredibly cold but the machines cost thousands of dollars now dry ice while not as cold as liquid nitrogen does get down to about negative 80 degrees Celsius and is available at most grocery stores so I was curious to see if it was cold enough to accomplish a glass only repair and it was as you've seen I set the broken glass screens down on the dry ice and let it sit for about five or ten minutes to get to temperature then I can lift up the screen and gently twist it with my hands to break away the glass from the LCD when I tell you to be gentle I mean gentle it's like trying to flex a Dorito without cracking I was able to use a razor blade and playing cards to help persuade the glass off of the LCD the iPhone six screen was easier than the iPhone 5 screen the nice thing about dry ice is that it's never actually a liquid so you don't have to worry about liquid damaging your screens it goes from an icy solid to a gas through a process called sublimation now this is also important to know because dry ice is made up of solid carbon dioxide carbon dioxide is not as good as oxygen when it comes to staying alive so make sure that you open any windows in your car or kitchen when you're transporting this stuff I don't want any dead do-it-yourselfers out there hit that thumbs up button if you enjoy oxygen I'm going to test the iPhone 6 screen by plugging it back into the phone and everything functions yes science it still has glue residue on the screen so I will need to clean that off apply the liquid optical adhesive and the new glass layer but all of that will be explained at the 8 minute and 20 second mark in the linked video dry ice is also extremely cold and can burn you yes ice can burn treat it like hot coal from a fire wear gloves if you have to touch it directly I imagine that with a $5 block of ice like this one an experienced tech could repair about four or five phones before it sublimates into oblivion the more glass I removed from the screen the quicker the screen warms up so I have to keep setting it on the block of ice to cool down and get the glue brittle again before I can break off more glass the iPhone 5 was much more shattered than the iPhone 6 but with my razor blade I could put a little pressure on each shard of glass and break it off individually it is much easier to work on a cold phone than a hot phone when I do is repair with heat it is blazing hot and almost untouchable the entire time now for those of you attempting this repair keep in mind that even though both of my phones were successful I've been doing this for a while for noobs the success rate is very low i broken hundreds of screens trying to get good at this so it might be more cost-effective and healthier for your sanity to just buy the complete screen and install that instead of trying to attempt the brain surgery equivalent of cell phone repair as you can see the iPhone 5 is also fully functional if you want to watch the Glu cleaning and liquid optical adhesive application and the installation of the new glass click the link and watch the video here starting at the four minute mark make sure to keep the local glue off the edges of the LCD so it does not seep into the backlight thank you so much for watching and subscribing my viewers like you make videos like this possible I appreciate it a ton leave any questions in the comments and I hope to see you around
