Microphone volume too low

Hi!
I wanna ask You, do You can help me to recover factory default Microphone settings? I've had it somehow changed, and now cann't set it back. Or how to put the Phone using Service Menu into the full factory default mode?

Thank You so much!
Zoli

When you mention "key input" what do you mean? I thought you meant to input using the phone app keypad but I can't figure out how to type letters. I'm trying to access the Service Menu and it seems I need to input Q0 but can't figure out how to enter the "Q". Thanks for your help.

Bro.....use those three dots on right top to select key input option.....then u can use key input.... To input codes..

If you press the phones menu soft key, located to the left of my note 3 Home Key, you will get the options you're looking for.

Samsung c9 pro.
I enter menu, but the rest is not coming.
Is there a way to version 6.0.1?
I read the whole thing but I could not find a solution.

You'll have to try ask on the C9 forum (or find a model that is close to it as more likely to be the same) this thread is for the S4 mini so yours is probably different

I dial *#0011# and only see a blank screen, although I am in service mode. Help

Unfortunately I don't have any new Samsung to test this on.
So I can only guess those effers have hidden it again!

Should be easy enough to find, if I get my hands on one.
(I stopped using Samsungs overpriced garbage, after I got my first Huawei...)

Hello, I'm trying to access the service mode main menu on the galaxy S8. I've tried several codes to no avail. When I use *#0011#, it gets me to the service mode. I've tried clicking the back, input "Q", back input "0000" to get to the main menu, no dice. Does anyone have the code to get to the main menu? Thank you

I'm hating myself today for asking so many stuff on XDA and one more dangerous than the previous one. I stumbled with this thread and decided to explore the settings trying to set a preferred band for LTE, but I actually moved something around the menu on WCDMA which I can't remember and I stopped getting signal, Sim card is detected and GPS and wi-fi are working. On phone menu where I should be able to select if I want 2G, 2G+WCDMA auto or, 2G+WCDMA+LTE auto I only get something about receiving on home are or roaming, the previous mentioned selection choices are goine. Is there a way to reset this settings or anyone can help me on any form?, imma try to reflash stock rom to see if the issue can be resolved like that

I found this another post from EVA, I promise I'll study a lot about it on morning to see if I can solve this by myself (10 pm here and haven't slept since yesterday, reason why I was so stupid).

If there is anyone willing to help me or present me to a quick solution that can magically reset the SM settings I would love you forever, you have no idea.

I'll upload screenshots of my menu later.

Okey I decided to pray to my goddess of knowledge last night, and this morning I figured out I messed up the options on Network Selection so I changed that again and now everything returned to normal, I attach screenshots of what I did for reference if someone else stumbles with this very same problem in future.

where to find the apk you are talking about

If for some reason you own a new (stock) Samsung phone, where you're not able to enter the Service Menu as described in OP, please locate and send me the "ServiceModeApp_RIL.apk". (Also give me the details about the phone model etc.)[/QUOTE

where would I find the info to send you? I have unlocked u.s. version of note 10+
