Headphone Jack too small for 3.5mm

To me this problem seems very strange as lots of people use headphones to make phone calls. In addition to this, probably 99% of smartphone users use it to listen to music on the go and audio therefore is the no. 1 feature and should be tested accordingly.

You’re right. Lots and lots of people use headphones and a very little number of people report this issue, so either they have cases or bottom modules with production flaws or headphones with badly designed or flawed pins.

I have looked into this a while ago and this is what I found:

I just went through the 4 threads you linked to and found 18 people reporting the issue only 4 of which still reported it after a module replacement and of them 3 tried with the same cheap headphone.

So from that small sample it looks like the main reasons are:

• flawed bottom module and
• cheap headphones
