Can I use JB Weld on a cracked touch screen?

    My son dropped his Nexus and of course it cracked the glass. The crack is on the side not affecting the view of the face at all and it has a couple of chipped pieces. I was just going to try filling the area with something like silicone, JB Weld, or auto windshield repair.

    I'm wondering if anyone might know what I can use that will not interfere with the touch screen. I'm thinking that silicone might be too much like "skin" touching that it might not work. Would like others' opinions.

    I think I'd be tempted to have the phone repaired anyway as cracks (assuming they go all the way through the glass) would make the phone even less water tight and thus even more likely to die from water damage.

    Also, if the cracks are big enough that some of the silicone might get through, you should definitely not try.

    Re whether or silicone would work: could you put some elsewhere, let it dry and see if the screen is sensitive to it?

    That's a good idea ST about putting the silicone on another area to see how it would react with the touch screen.

    About repairing, I wouldn't have any problem attempting the repair, but found that the cost for getting the lcd plus digitizer would cost more than just buying him another tablet (albeit it wouldn't be a Nexus) for between $90 to $100.

    The cheapest lcd + digitizer combo I believe was in the neighborhood of $139.

    What are you trying to accomplish by filling? Just to smooth jagged edges? If so, hot melt glue should be perfect.

    If you're trying to prevent crack nucleation, I think auto windshield repair stuff might be your only effective option.

    Worst part about the tablet, the screen breaks and it is just about worthless. You might just be better off putting a screen protector over it instead of trying to repair it and possible making it worse...

    Apparently you've never had a laptop fall onto the floor after a dog got caught in the power cord, and then discovered the cracked screen. Tablets are a bit more durable. My Nexus 7 first day fell "butter side down" onto concrete and hit directly on one corner, and all it did was put a very fine, hardly noticed scratch on it, and dented the silver bezel. Had that been a laptop the hard drive and LCD would be gone. FYI screen protectors stop scratches but don't do anything to stop cracks

    Is this what you are looking for?

    That's not entirely true. Cracks occur when the stress on the glass is higher than the bond between the glass molecules. The bond between the screen protector and glass is not as strong, but it does divert some of the impact loads away from the glass (therefore the stresses in the glass are lower) and into the protector itself. So for borderline impacts, a screen protector could prevent the glass from otherwise cracking. :)

    I'm just amazed that it didn't shatter the Nexus 7 screen. I read reviews saying that they shatter in pockets so I was pretty relieved concrete didn't do anything. Especially given the nature of the impact. Five feet off the ground fell, hit the lower right corner directly then fell screen down and slid a few feet. I had it on top of my laundry basket and it just fell. Stupid idea I know.

    I did a search on Amazon, don't remember what my exact search for was, but the only ones that came up was like

    For Asus Google Galaxy Nexus 7 Tablet LCD Touch Screen Digitizer Assembly Parts


    LCD & Digitizer Assembly for Asus Google Nexus 7

    I did go on Ebay and got them for $65.

    Since I did purchase this on Ebay, I went ahead and decided to try an epoxy using Loctite's Glass glue figuring if it did kill it, no big deal.

    Just to complete this thread and so everyone knows, it didn't work. The touchscreen is not working now.
