[Q] Can barely hear my speaker on max volume

Hi, all.
After Android 4.2 update I can barely hear any sound coming out of my N7 speaker. I mean, literally - I have to put my ear next to it to hear anything (but there is some sound, just really quiet). With my headphones the sound is fine though.
I tried resetting to factory defaults, but that didn't fix it. I tried using Volume+ for increasing max volume, but that changed almost nothing.
What can I do?
Hi.
Did you try a hard reset, as described on google support ? :
######
If your tablet is on, power it off.
Press and hold Volume Up + Volume Down + Power until the device powers on. You should see an image of an Android lying on its back.
Press Volume Down twice, until the screen says "Recovery mode."
Press Power to restart into "Recovery mode." You should see an image of an Android with a Red triangle after a few minutes.
While holding down Power, tap Volume Up
Use the volume keys to scroll to "wipe data/factory reset" and press Power to select it
Scroll down to "Yes - erase all user data" and press Power to select it
Note: If at any point during the above steps your tablet becomes unresponsive, you can restart it by holding down the power button for several seconds.
#############
If that doesn't work, I (personally) would try to flash a factory image via fastboot.
If you don't know what this means or you don't want to do this, I would contact your reseller/google for a swap of the device, after you tried the hard reset above.

I'm not sure - does that differ from the factory reset that can be done in Settings? If not, I have already done that.
Well, give it a shot?

[Tip] Make the SOD's a little less annoying

If you're here at XDA, it means you flashed a ROM or two (or 10... 20... 1434240 )
If you've flashed any ROM, you probably encountered SOD's before.
You probably took out your battery and put it back in, in order to restart the phone.
But, recently I found out that you could just press and hold
Power Button + Volume Up Button
to restart the phone! (hard coded reset )
So as the title said, it won't prevent any SOD, but will sure make them feel less painful!!
hi,
i usally just press my power button for a few seconds and it reboots as well - i dont know if there is any difference if you press volume up as well.
best regards, dv
Correct procedure is: Home button + power button.
No, dervaganund is right. You can just hold your power button for a couple of seconds to shut down your phone, or hold it longer for about 8 seconds to reboot your phone. No need for volume or home buttons

Problem with A3 SM-A300FU

My A3 doesn't "wake up" from stand-by.
If I reset it keeping pressed power up button, it correctly reboots, I can see all boot process and it correctly reachs the starting home page.
If I keep touching screen, open apps, navigate from various menu all works fine. But when I leave it without pressing any button/screen for 10/15 sec (display power off delay) the screen correctly goes black, but there's no way to wake up it again although it seems working. The A3 "under" works because plugging to AC Adapter beeps the sound of charging in progress, PC (Kies or SmartSwitch) detect it correctly; only the screen remains black.
I already tried to wipe and even reflashed last firware with Odin but with no luck.
Is there anything else that I can try (except send it to repair center...)?
Thanks in adv

P.S. When I call It from another phone, it rings but the LCD remains black and doesn't respond clicking vol +, vol - and home buttons
P.S. 2 Thinks become "funny": Home button, vol + & vol - don't work at all. Power button powers off display, but long pressing it, doesn't pop up power off/reboot menu. Softkeys don't work.
Sounds like SoD. Try installing the app "Wake Lock" and choose the PARTIAL_WAKE_LOCK option.

Fast fast try to return it before Trump wins . He will build the wall you know... Jk...
For my opinion LCD has to be changed. Due drop or in your pocked from high pressure i think its gone ...
Since as you said phone is working you can take pictures or receive calls but screen is always black.
Can you see its black color or screen isn't turning at all.
Sent from my ONEPLUS A3003 using XDA-Developers mobile app
Mine started with green stripes allover the screen and few days later - "black screen"
Samsung change the whole unit.
But if lcd doesnt work so, it wont recognize when i press the screen, can it?
Anyone with this problem

S7 Edge BSoD Extra Info. needed
Hi,
Phone: I have a Samsung Galaxy S7 Edge SM-G935FD
I was using my phone to send a txt (and at the same time I think I was receiving a text or call because the menu and back touch buttons were lit up) and all of a sudden the phone crashed as I tried to finish my text but the touch wasnt responding, then the backlight turned of like it does if the phone is not being used. But the strange thing was that the menu and back touch buttons stayed lit up (Solid).
I tried many methods to restart the phone:
Power button + volume down (FAILED)
Power button + volume up (FAILED)
Power button + volume down + Home (FAILED)
Power button + volume up + Home (FAILED)
So I thought I'll let the battery die and then recharge and hopefully the phone would automatically restart like normal, however the phone does not show sign of charging now.
So I tried to connect to the PC but it wasn't being recognized however when I press and hold the power button a sound of detecting a device sounds and then when I take my finger off the sound of detaching occurs. But I couldn't see anything happening, until I went into device manager, under "Other Devices" , "Exynos8890" appears which I know is the chipset.
This is as much as I know of the problem. How do I solve thins problem without trying to factory reset the phone and lose all my data?
PS: I didn't backup my photos (My baby children only copies) or Notes in NotePad, which has some very important info.

can't make hard reset nokia 6

hi
my little brother made a pattern lock and forgot the pattern, after many tries the phone erased everything
he doesn't know the email he used it on phone or the password
now it boots welcome screen and asks for the old email, i did tried make new but it doesn't works.
so i figured i should just wipe everything with hard reset
from what i read and saw some videos, i should turn off and then connect to power then wait a little, then press power and vol up for 10 seconds then release my finger from the power button.
i tried it many many times but it doesn't works.
any help?
Switch off your phone,then connect the charger to your phone and quickly press and hold volume up and power buttons,after the screen is blinking a bit release power button,but hold volume up until you are in recovery mode.
it doesn't works, it's like the vol up doesn't work when the phone is switched off, but when i power on the phone and finish booting i can vol up.
i can enter download mode (vol down + power) but it doesn't do anything.
