![]() After a few seconds of heating, use your razor (or whatever pry tool you decided on) to go underneath the glass and start to pry it up. Anyway, start to evenly heat up the very top of the screen where the Samsung logo is. For instance, the Galaxy S4 digi flex is in the upper left corner of the screen. This is important because you need to be weary of cutting or damaging the digi flex while you start to pry the glass up. AMOLED screens have the touch screen integrated in the display itself and have both a display flex cable as well as a digitizer flex cable. Also, always look up information about the hardware configuration of the screen you're working on. The LCD will work, but there will be no way to ever buff out that blemish, and you might as well just replace the entire screen assembly if it happens. DISCLAIMER: IT IS VERY IMPORTANT TO NEVER HOLD YOUR HEAT GUN OVER ANY PARTICULAR PLACE ON THE SCREEN FOR MORE THAN A SECOND OR TWO AT THIS TEMPERATURE!! It's very easy to destroy the LCD even through the glass relatively quickly, and if you see any unusual discoloring behind the glass while heating, just give up. but I like having it up high so the screen heats up fast. A lot of you will think that is high, and you're right. To begin, I turn the heat gun up to 300 degrees C. Oh, and obviously, you will need a replacement glass panel for your particular device.Īlrighty. I'm not sure of the gauge I use, but it's as thin as strong fishing line. You will also need a very thin pry tool (I use a very sharp and very thin razor blade), a pair of gloves that will protect you from heat, and most importantly. The ability of a heat gun to heat up specific areas of the glass on demand makes the method I use much easier. I read that some of you use a temp controlled hot plate which can work I suppose, but I strongly suggest using a heat gun with the ability to set the temperature. Personally, I use a temperature controlled heat gun. Also, you will need a way to carefully heat up the screen during the repair procedure. So, as I've said, you will require some UV cured LOCA, and a way to cure that LOCA as well. ![]() That being said, if you can have the necessary tools at your disposal, the following is how I repair AMOLED screens to an almost new condition. Even if you purchase the correct LOCA, it is useless without having a UV oven to cure it. Using regular adhesive around the edges of the glass replacement will result in an ugly and dysfunctional touch screen, and will eventually fall off and/or fail. Most of you probably know this but for those that don't, LOCA stands for "Liquid Optically Clear Adhesive" and is an absolute necessity for replacing cracked glass on most if not all AMOLED screens. You should be aware that you will require both LOCA AND a UV curing "oven" (<- that's what I call it) to correctly repair these screens. That being said, there is a way to replace the glass of any AMOLED screen if you have the right tools.Īs a disclaimer, I should warn anyone before trying to repair any glass on an AMOLED screen. Granted, an 8.4 or 10.1 inch screen is at least 3 times the surface area of any of Samsung's smartphone lineup, so it should take more time. I've repaired the glass on hundreds of Galaxy S3/S4/S5 during the last 3 years, and the way I do it takes about 10-20 minutes (depending on how much the glass is actually shattered). I figured that like all AMOLED (as far as I know at least) screens in Samsung devices, the glass was bonded to the LED with LOCA. I too cracked my tab s 8.4 glass several months ago. I am an experienced cell and tablet repair tech, and have some insight. I originally posted this as an answer for a galaxy tab s glass replacement procedure, but it is relative to most AMOLED glass repairs, so I'm copying it to here as well (I apologize for the length, but I wanted to be as thorough as I could be).
