Lg G Pro 2 D838 - Phone not detecting headphones (HELP)

Weird thing started happening to my phone... When I plug in a pair of headphones (with or without mic) the phone does not detect that they are plugged in! Sound always comes out of the speakers. I've used apps like SoundAbout to force sound through the headset jack and it seems to do the trick but I'm still trying to find a proper solution for this problem.

The odd thing is that if I turn off my phone, plug in a pair of headphones, and then turn my phone back on, once booted the phone will recognize that it has a pair of headphones plugged in and everything will be fine. It doesn't work when I unplug and try to replug. It only detects the headphones on boot.

1) Is there a solution to this?

2) Anyone know something about mechanics of the 3,5mm jack? How all of this works? It seems that on boot it always tries to check if headphones are plugged in but I suppose that something mechanical in the headphone jack must trigger the check after boot...

3) I have cleaned the jack properly so dirt is not a problem. I have also tried different headphones and none of them are detected.

4) I think that problem is not software related. I have booted my phone in Safe Mode and problem is still there.

If anyone have some suggestion please help!

Thanks in advance.

Not Detecting headphones plugged in

I've had this issue for awhile now across multiple roms. I just today tried an app called soundabout and it detects my headphones fine when plugged and unplugged. This definitely means there is a software issue causing the problem. I'm currently on Cataclysm (Lollipop) and Franco Kernel (latest version). Any suggestions or fixes?

android not detecting internal storage free space correctly

hay people,

so, today my friend gaved me his phone and asked me to install him facebook application on the phone, because he faild to install it.
so, i thought what an easy task, but it turns out i can not make it work at all.
so, he has samsung galaxy s4 (model: GT-I9500).
he has sd card which is 16 gb large, and his phone has 16 gb of installed storage. (at least phone specifications say so).

i tried to install facebook but i got the error.

the problem is that it says that there is no enouff storage available, and google play fails to download application.

so i went to the settings and some wery odd numbers i found.

so, it turns out that storage section of settings shows that there are three different storages.
first one is sd card.
for sd card it shows that it has 16.53 gb capacity, and that 13.97 gb is free.
second one is internal storage:
it shows that internal storage has 16gb capacity, from whitch (believe it or not) 15.91 gb is free.
furtermore, what is also strange is that it shows that there is third storage called "phone storage", and it shows that this storage has capacity of only 17.84 mb, and that 17.75 mb is free. but mb not gb.:eek::eek:

what is even stranger, if i go to applications section of settings to see installed apps it shows that available space for apps is 170 mb from witch about 40mb is free.

i mean wtf, how is that possible?

phone has 16 gb of internal storage, and almost all is empty, there are no installed applications except for built in ones, and still it looks like it lacks free space.
it almost looks like it looks at this "phone storage" for available space to install.

what is that "phone storage" at all?
why is only 17mb large?

and how to make android detect that there is 15.93 gb of internal storage available?
instead android shows that low space icon in status bar and every 5 minuts displays popup saying "internal storage is full".

please help to solve this.
why those 15.93 gb are not available for applications?


also, phone has an option to choose where to install applications.
and no matter what i choose (sd card or internal storage) it says there is no enough storage available.


please help.
i really want to fix his phone, because if i do not, you know, he would think that i do not know how to install facebook app. :(

any help?
how to solve this?
is this normal?
is there any system reserved memory or something?
if this is normal, than can someone explain why, what is all that free memory used for?

for far as i concern, i am down with ideas only to reset phone. but, i am hoping there is some better solutions.
for anyone who reply, thanx!
