So basically, I must have damaged the jack socket of my Redmi Note 3 (OS: Android 6.0.1 MMB29M) - now with any kind of headset (I've tried many!) I can only hear some audio channels, while the rest is almost completely cut out (plays at extremely low volume - it can be barely heard). For example, I can tipically only hear instrumentals, and not voice, while listening to music - irrespectively of the audio player I'm using.

Plus, my phone does not really detect headphoes when I plug them in, so I had to resort to the "LesserAudioSwitch" app that, if I understood it correctly, forces the phone to use the "headphones" audio out even if it detects no plugged device.

To try and understand what the problem is, I downloaded the app "Stereo Test for speakers & headphones" by Pasta Panda Entertainment and run a test. What I get is that I can hear perfectly clear sound when I test the "L" channel, and the same when I test the "R" channel, BUT I only hear extremely low and distant sound when I test them "Both".

This makes me think (but I could well be wrong) that these three choices correspond physically to three separately wired channels in the jack, and that one of them is not working properly. I would like to know if this is true, and if there would be any way to redirect audio from one channel to another in order to be able to properly listen to music - even at the price of sacrificing stereo sound.

Bonuses: 1 - actually my Bose PC speakers are recognized correctly by my phone and with them none of the described issues takes place; they just work perfectly. I cannot understand why (???).

2 - I DON'T have any option for balancing or switching between mono/stereo mode on my phone, not in the accessibility settings nor anywhere else (it there's something, it is incredibly well hidden...).

Thanks in advance for any help!

My phone dropped in water about 30 days ago. I couldn’t open it at the time so, I put it in a rice bag(which I later learned does nothing). After the phone was dropped in water, It was stuck in a bootloop and there just wasn’t a way to turn it off to prevent damage from water left in it.

I charged and restarted it 15 days later, Around 25 November. It started but touch was not working so I couldn’t enter my passcode. On 6 December, I bought a replacement screen from aliexpress and replaced the screen. In the process of doing so, I broke the Volume/power button cable and the socket in which that cable is plugged into. So, I ordered another volume/power button flex cable and replaced that as well. Since, The Socket was broken I inserted it in the socket just right and screwed in the shield.

Now, It doesn’t starts when I press the power button presumably because the battery isn’t charged at all?

When I plug in the charger, It gives 2 short vibrations, 1 long vibration and then starts and I see the MI logo but then It just reboots!

Sometimes, When I plugin the charger, The Red LED at the bottom just flashes at 0.5-1 second interval but no vibration and screen doesn’t starts either.

I left the phone to charging for a few hours and then tried starting it but that also didn’t work.

Then, I thought maybe something is wrong with the charger circuit at the bottom of phone, So, I got a donor phone(redmi 3s prime) from a friend, His phone was bent in half. I replaced the charger board of my phone with the one on his phone but that also didn’t work.

I also tried replacing my phone’s motherboard with his phone’s motherboard but then the phone doesn’t vibrates and there is no LED light.

I am completely lost at this point, Please let me know if there is something else I can do to get this to work.

I already bought another phone so it’s not super important to get this to work, But I am attempting to fix a phone for the first time and it would be nice to make it work.

Here is a picture of the socket I broke while replacing the screen. https://imgur.com/a/gy11SMd

I have a problem with my phone.

The phone is charging very slowly (150-300mA)

If the phone is switched off and connected to the charger, the red LED blinks and can not be switched on.

The phone only starts when I disconnect it from the charger.

PC does not detect the phone. After connecting to the PC there is no reaction.

I have already replaced the USB board. It still does not work.

I already made sure the flex was correctly attached, I also booted without the flex and the backlight disappeared, so I think that is not the problem
