Why dissassemble entire phone to replace broken glass?

Hello,

you take apart the whole phone because the heat that is applied to the screen can damage the internals.

Edit: I know you need to apply heat to the back but it's safer.

It's just to protect the smaller components from the heat.

To be frank, I just removed the motherboard and carefully apply heat as I disassemble the LCD/Digitizer.

Once I get an opening I just apply small amount of heat and go through the adhesive in the back. I've never had an issue with this process.

The only time I completely disassemble the phone is when I need to preserve the LCD, this is for S7 and lower that requires you to get some access to the LCD to remove the motherboard.

good luck

You are right bro. I think no need to dismantling a whole phone especially only broken front glass . Heat up upper side slightly and pass wire between lcd and glass and seprate by intermittent heating and pulling wire , overtop at earpiece mesh. Care should be taken to LOCA applying is must .mask with tape entire rim of phone precisely before pouring of LOCA. Then clean exess and put under UV for curring. That's It.

I cannot find a shop in town that will replace just the glass, one shop told me that the deal they have with Samsung is replace frame and digitizer on your phone and give you a discount if yours already works. Stupid.
