I had exactly the same problems and i think i found a workable solution:
symptoms: ghost clicks, trouble tapping, somtimes very fast, somtimes touchscreen only unresponsive. It had some bad moments and some good moments too. after all it was ok to use.
i have to tell you i have done multiple repairs (at least 30 iphone 5 screens alone) and this was the first time ever had this problem. I know what im doing with the flex cables, everyting went als normal.
first repair attempt: i checked with another screen, maybe only the digitizer was broken. This second screen was an original iphone screen with broken glass. The results were the same :(
second repair attempt: i did everything i read above (plastic behind backlight, covering the contacts of the backlight. No result.
-
third repair attempt: i started testing when it went wrong with the digitizer using test flex cables. i started noticing that the ghost click appeared when i was moving the screen (it was not attached in place in the iphone) Then i noticed when i touched the flex cables with my hands the ghost clicks appeared even more. My theory was that if the lcd flex and digitizer flex touched each other, random taps would appear. So i took a piece of paper and put it all the way starting at the backlight until the connectors in between those flex cables. I assembeled everything and now the digitizer works perfectly. Only when i press real hard on the corner where the flex connectors are, it can sometimes be unresponsive for a very short moment. Its not perfect yet but i you don't press explicitly on the corner, the digitizer is perfectly normal.

My theory was that if the lcd flex and digitizer flex touched each other, random taps would appear. So i took a piece of paper and put it all the way in between the flex cables. starting at the backlight until the connections on the motherboard. I assembled everything and now the digitizer works perfectly. Only when i press real hard on the corner where the flex connectors are, it can sometimes be unresponsive for a very short moment. Its not perfect yet but i you don't press explicitly on the corner, the digitizer is perfectly normal.
Hope i could help some of you, i had a real hard time finding a solution for this problem, if it works, let me know.
