What are those "2 dots" at the bottom and above the bezels? - Sony Xperia XZ1 Compact Questions & Answers

Just got my XZ1C and immediately noticed a mic\reset button looking holes next to the USB socket and headphones jack. I searched everywhere and no one seemed to mention what those are.
Well, what are they then? :laugh:

Saved by the Headphone Jack

Today my phone slipped out of my pocket. It slid out while I was attempting to change songs. I didn’t even look down. Just waited to hear the sound of it hitting the ground. Thankfully I never heard that sound. I looked down and the phone was dangling inches from the cement; saved by my headphone wire.
Question 1) Is this by design? The female/male connection of the 3.5mm jack seems unusually snug*. The USB by comparison sometimes falls out.
Question 2) Are there any apps that utilize the volume rocker to change the songs on the music player?
*that's what she said
I think you just got lucky *
I order to give good audio quality, the jacks need to be snug, better connection. I've seen many instances where I'd need to replace headphone jacks in computers because they wouldn't snap in firmly and not make good connections. If you held it at the right angle, music would play, but not without crackling and popping occasionally.
I have no clue if there are any apps. I imagine that would be more a limitation on the plug portion than the programs. The Aria did it, but I know there are particular types of headphones that have them built in that speicifically will/will not work with the phone. Just have to try.
*that's what I said. Just now. See, I said it. Earlier in the post. First line. See?

is my captivate's headphone jack broken..or is it the headphone?

hi: So my friend gave me a pair of dr dre beats(tour) earbuds. I plugged them in and everything sounds fine on the phone, but I realized today that when I wiggle the wire near where it goes inside the jack, my music stops. As if my phone thinks the headphone has disconnected. So for example, with double twist, if the wire moves, the song pauses, and I have to press the play button again. I tried a friends Seinheiser headphones, and when I wiggled them, there were no problems. What should I do?
If the head phone connector is gold and appears to be wearing off it just means that thee signal is not making it to the headphones. Gold plated connectors is a way to make a cheap cord better but once the gold wears off the signal strength weakens. I have some really nice dj quality headphones that sound amazing but it can be hit or miss bc the gold is going
Sent from my SGH-I897 using XDA App
just make sure its pushed all the way in.
some headphone jacks are cheap and just dont sit right.
just feel for the click.
if everything is fine there, wiggle just the wire part.
ive had many headphone extention cables break internally and they cut out.
if no other headphones do it, id assume its the headphones,
btw why did your freind give them to you? theyre expensive,,,
it's probably not the jack afterall... i put ipod buds in my captivate and the sound played fine...probably the dre earphones since when i plugged them into a mac nearby and i went to listen to a youtube vid after twisting the wire tip around the sound was lost. thnks anyways
i have the same problem when i plug into the an audio jack from my car stereo.
when i plug it in the right side normally goes out. takes some wiggling of the wire to get sound to both sides.
my friend has the same problem so i think that maybe the jack on the phone is cheap. who knows. maybe ill try another cord.

Headphones extension cord

I've been thinking about this for some time as I have some nice headphones (HeadDirect RE0) that I use with my Defy. But I miss having a microphone (taking/making calls without too much hassle). So I thought of cutting off the headphones of a Nokia stereo headset and putting a 3.5 plug so that I can have an extension cord with microphone.
I searched around the net but didn't find a good pinout so I opened the Nokias. They only have a 470ohm resistor (if I remember well). I tried to rewire those (to get a button push) with no success.
So I opened the original Motorola headset (quite easy and with no damage) to find quite a circuit inside. I'm putting the a picture of the circuit here, maybe someone with more experience can help me. The circuit is quite small and as I have minimum experience with circuits...
PS: I was thinking of getting a third party headset, but at about 10 euros... kinda expensive to break.
Heh, this is how i modded my headphones - got Creative EP-630 headphones, but no microphone, and sucking (compared to senn) motorola ones.... ...and voila!
Take pilot/microphone apart --> solder out old connections --> cut new headphones cord somewhere like 20 cm from headphone -->solder them in to original connection points.
EDIT:
Ohhh... and the worst part was to carefully remove original rubber gasket around original cables which were to be removed, and pulling/glueing new cabling through it. But the effect is awesome - there is almost no visual hint that someone modded them
..and sound quality....
I was thinking that I could get away with it without taking apart the original headset, but it looks like I'm slowly getting there...
Thanks for your reply!
I have a sony headset with mic, but they have the old sony ericsson socket. Could it be possible to solder a 3.5 jack onto them. Are the even selling 3.5 jacks with 4 rings?
I don't know if you could find a 4-rings 3.5 jack? Check the closest electronic parts shop. Or, if you have a Nokia headset lying around like I had...
From what I've found out the mic and headphones work OK just connected to the respective rings*, but what I couldn't make work is the button. As you can see in the attached picture, there are a few SMD capacitors.
*if I remember well, from tip: Left, Right, Mic, Ground (Corrected: Left, Right, Ground, Mic!!!)
Cheers!
NO.
There is right:
Left, Right, Ground, Mic
This is my modification:

Fixing the crap microphone issue on a single Din unit

I've spent hours reading the various threads since getting my HU last Novemeber. Absolutely love it, especially with the Malaysk roms on, does everything I could want it to, except make a bloody phone call. If the other end can hear me it's very faint at best.
Mine was supplied by Pumpkin, they have tried to help with a microphone app and various settings, none made the slightest difference.
There were a few posts about adding an external mic by finding the BT card after dissasembly and wiring to the mic+ and Sgnd legs on the card. Last night I eventually bit the bullet and took mine completely to piecese. Unfortunately I couldn't find a BT card, maybe it's built in, or on chip or...... But I gave up looking for it. What I did find on the front panel was the original pathetic little mic, way back from the tiny hole. You can't drill it bigger as it knocks the mic out of place.
My fix, made simpler now I know what I'm doing (it took me a lot longer and many more steps.
Take off main case
Pull tape off DVD drive to extend ribbon cable
Flip up black tab at the back of the ribbon cable connection on the screen and slide out ribbon and put screen aside
Remove two small screws from the side of the faceplate and using a flat blade screwdriver release the faceplate
Flip up tabs on both ribbon connectors and remove ribbons, I found it easier doing the short one first
unscrew all circuit boards screws in the faceplate circuit (7) and remove faceplate
Drill a hole in the rear of the unit above the ISO connector to feed a cable through
Carefully desolder the horrible little mic from the right hand side of the circuit (labelled mic1) and clean the holes
Take a mini jack extension lead and cut off the male end - either a mono one or if stereo you want the wires for the top part and the middle part of the connector stripped and feed through the hole, I also put a very small tie wrap inside with the tag outside so I could hold the wire tight and not strain the solder - tightened after assembly
The positive (top part) goes on the inside connection. I soldered this to the top of the board
The ground goes to the other terminal - these are so close together that I soldered this on the underside to ensure no contact
Reassemble in reverse of above (making sure all faceplate buttons are in place (yes I forgot the eject and screen buttons)
Then connect any unpowered condenser Mic and all of a sudden fantastic vocie clarity, quite a phenomenal difference.
I used this mic from Amazon, https://www.amazon.co.uk/gp/product/B01F84YMZQ/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
Happy for this to get merged into another thread, but I couldn't find one specifically about the mic problem with the single din unit.
Was there no factory fitted connection for an external mic? Mine does have one. Then it would be simple to just disconnect the internal mic right?

No, no external mic connection on the single din units. Confirmed by Pumpkin. Bit of a silly oversight

Top loudspeaker not working

I recently got Nexus 6 and noticed that when listen music the top loudspeaker not working, just bottom.
When making and receiving calls i hear everything like it should.
I'm not familiar with this phone, is this normal or it should be playing music from both top and bottom loudspeaker?
Is the top loudspeaker and earpiece the same hardware?
There is only one loudspeaker at the top.
To me it sounds like a software issue. Have you tried a different music player?
Hmm, i use Youtube app, not tried anything else.
Did the factory reset, its the same, loud and clear from bottom loudspeaker, from top nothing.
I'm sure there is the bottom loudspeaker, here is topic about replacement.
https://forum.xda-developers.com/nexus-6/help/speaker-replacement-t3379395
On my phone, the volume from the top speaker is a bit lower than from the bottom one. But both are active in YouTube.
Which rom do you have on the phone?
What happens when you hold the phone differently while playing. If you hold it with the top to the left, the top speaker should play the left channel, but with the top to the right, the channels reverse.
Rom is stock 7.1.1, not rooted or anything.
I tried to rotate the phone while playing but nothing change, only bottom speaker working, top not at all.
That was the hardware problem.
I disassembled device, it was not so hard because it was already opened in service centre couple months ago, so the adhesive was not that strong.
Removed middle frame, the top speaker is in it.
I checked the speaker with multimeter, and it was ok.
Then I saw the small flat cable where the speaker seats on, and see It is broken somehow (tested with multimeter also).
I had the broken middle housing and managed to peel off the flat cable (very slowly with hear dryer) and replace it.
Now everything working, and the sound is playing from both speakers.
Thanks.
