Iphone 4 receiver not working so cannot hear caller

This post helped me even now, after 2 years. I have an iPhone 4S and i thought the receiver was destroyed by a dropplet of rain. I got on the internet and started reading. After doing this:

This solution worked for me. My phone is working fine now. Please try this:

"Plug the headphones back into it. Then turn on the ipod and play music. Then pause the music and unplug the headphones, and the receiver will work. If you accidentally pull out the headphones while the music is playing it somehow kills the receiver speaker untill you plug it back in pause the music and thern unplug them." -SlimNick (modmyifone.com)

Please reply back if you still have issues.

My iPhone 4S receiver with ios 6+ was working again.

THANKS!

i also got same problem but i hit slightly on a back side below the camera of my iphone it started working

I had this same problem with my iPhone 5, and running through Apples troubleshooting checklist for this problem as well as all other tips I could find (in this thread and others) didn't solve the problem for me.

So I checked in with a friend who works at an Apple Store, and he said that the most common cause for this problem (for the phones that ended up being brought back to the store at least) is that the phone is literally starting to come apart (ever so slightly, but enough to cause problems). Sometimes, he said, they can replace just the glass and patch everything back up again and the phone is fine after that, but usually they end up having to replace both the glass and the display to fix the problem. And, apparently, if the glass or the glass+display comes ever so slightly loose this can end up disconnecting the receiver as a result.

So my friend asked me to check around the edges of the glass around the receiver for any visible damage or signs of the glass coming loose from the handset, but I saw no such signs of any kind (or, the glass at least looked the same at the top/receiver end of the phone as the rest of the phone). But, I thought if the problem is just that the phone is coming apart, then I should at least try pushing it back together again, and squeezed hard around the receiver opening and around the edges of the top part of the glass, and lo and behold … that actually fixed the problem for me. Well, at least temporarily.

For me this wasn't a really solution, though it certainly helps. Sometimes I can now finish a phone call while sitting still after first applying pressure to the glass, but oftentimes I pretty much need to constantly (or at least regularly) apply pressure during the call for the receiver to work (especially when on the move), which of course isn't very practical, and certainly not a good option for longer calls or when making many calls. But at least I've now identified the actual problem.

I hope this info might help others with the same problem (since I myself didn't find any info that identified this particular "solution" online).

The next problem I'm facing is the fact that I'm out of the one year warranty so Apple won't just fix the problem for free (even though this is clearly a problem with the phones design and/or assembly process). But since I live in the EU the law says that one year warranties aren't enough and that all companies need to provide at least two years (as a minimum within the EU, though some EU countries state more than two years). But the law appears to only apply to the resellers, and not to the companies that makes the products. And since I bought my phone directly from the phone company and not from an Apple store, this is problematic. In theory I could go to an Apple store and have this problem fixed (while I wait, possibly, at least if I could book a time for that), but in reality I need to mail in my phone to the company I bought it from, and then wait for them to send it on to Apple to be fixed at whatever point in time they see fit, and then wait to have my phone sent back to me. So if I want the problem permanently fixed I'm gonna have to do without my phone for an unspecified amount of time, which doesn't seem practically feasible even. Using my iPhone as a phone is about the least use I get out of it these days - it's a pretty integral part of everyday life at this point, and without it I can't even identify myself online for like bank stuff and whatnot. So the current setup looks a lot like a conscious deterrent to me, more like a system set up to keep people from returning their broken phones than a system trying to help people get their phones repaired. And of course that's only for phones out of the first year of warranty, and only for phones not bought directly from Apple (which I assume is the majority of the phones sold though, as most people seem to buy subsidized phones through their phone providers), but still … so … I'm eagerly awaiting the day Apple just extends their regular warranty to match whatever period of time the law requires in any given country/territory, or at the very least allowing people who buy their iPhones from their phone providers to book a time at an Apple store to have their phones fixed while they're waiting. I can of course achieve this, but only if I pay for the repairs myself rather than using my legal right to have the repairs made for free. So the current setup is far from ideal from a consumer standpoint. I love Apple and have been an avid Apple user since 1986, but it's disheartening to see the company trying to dodge the consumers' legal rights the way they currently are. And even after being sued for their practices elsewhere in the EU, it's clear that the information on their website is there to obfuscate rather than informing the customers about their legal rights. And that's really not how I want my favourite company to conduct their business.

Time will tell if I bend over and let them screw me royally, or if I'll just keep using the phone as is until I get a new one to avoid the hassle … which I suppose is just another way of bending over and being screwed royally. ;-)
