iPhone 6 touch not working after applying OCA.

So I use the glue remover and polarizer remover, clean the LCD and apply a new polarizer layer. I tried redrawing the leads for the static also. I have done about 6 LCD's and none of them work with the touch. You can touch it at the very top and bottom but the middle is unresponsive. I've tried different oca's but nothing. Am I missing something? If I apply just the polarizer it works fine. As soon as the oca touches the LCD, the digitizer is unresponsive.

Answer this question I have this problem too

Is this a good question?

I am working on it as-well. I was loosing total touch in the beginning running standard settings on the Vacuum lamination machine and then the autoclave. I now run the lamination at 1.2 on the gauge instead of the standard 2.7-3 and the plate drops extremely slow. Also I run it manually, I have the plate drop "watching it" and only let it laminate for 1-2 seconds then hit the "red stop". Now for the Autoclave I have turned it down to 2.7 from the preset 4.2 even though all the info available says 6.2 is OK. its way to high for the 6 from my findings.

This is as far as i have got and am not losing touch anymore. But its not perfect and i still think the polarizer need some looking into. Touch still works with this method. I hope to find the exact problem and solution soon. I only know what it is not. its not the conductive glue, its not the glass or OCA because some are perfect and others are not with the same material 50+ units tested. I encourage you guys to test at every stage, seek out the best quality refurbish parts and try to run your machines at as little pressure as possible. I am going to run another few units tomorrow and just keep turning the machines down till they will not work and then try to operate just above that threshold.

One thing is for certain the YouTube videos and the machines they are promoting are in no way addressing this real problem? Makes you think WHY?

Thanks Adonees it looks like you are working hard on this problem also. I have seen a refurbished unit in my shop that was glass only in China and had conductive glue at both right and left and again in the center at the connector not connected to right or left? The easiest way to know that its not the OCA or the Glass like many have suggested is to install a glass screen protector. The screen should preform as normal. when it will not you know you have a problem.

You will not have as much problems with static on the i6 just replace with "conductive glue" only a small line on each side. The only time I see "red ring" static is on i5's. Its caused by a bad conductive glue or a cheep polarizer "Original's are more like card stock" and easier to work with.

For the static I usually follow the original standard after putting polarizer you can put two drops one upper left and right corner the drops should touch the polarizer on each corner this is for iPhone 6 and you can take a photo after removing cracked glass and apply them as it is
