I had found a way to solve dust in FFC problem. But it may not apply to everyone whose phone also plagued by this.
Yes, I can confirm there is a gap between the case and screen, with a layer of black rubber bump supposedly to seal the gap but obviously didn't do too well.
It's really hard to see the hair thin gap without proper lighting or magnifying glass. However, If you look into the gap, you can clearly see the stopper wall of
polycarbonate case behind it. Mine is easier to tell since it is yellow.
Ever since first getting the phone in mid-Oct last year, I had suffered this recurring problem and gotten tired of blowing compressed air into the gap to clear the dust from
time to time. Like some people said, I too don't really care about dust getting into FFC, what really annoyed me is the blackout screen during call as the dust had
hindered the proximity senor. Didn't want to go through the hassle of getting the phone replaced, here is what I did:
After blowing off the dust one last time, I did a micro-surgery to the phone by using a needle threader as a tool to apply some translucent silicon sealer to seal the gap.
I am happy to report that over 5 weeks has passed and have never seen any new speck of dust in the FFC, nor did I see proximity sensor malfunction during call.
It's a pain to do the micro-surgery, but with proper tools, I think it's worth the effort. I did it with great care and use minimal amount of sealant as possible, so you
can't tell by appearance. Do it at your own risk and YMMV.
