[Redmi 9 Power / 9T] SamueruSama:
I recently got this smartphone, and one of the very first things that I noticed is that volume thru headphones is very low, this affects the 3.5mm jack, USB-C audio and even bluetooth. It is in fact much lower than on the previous Redmi 9 which I compared with.

Doing some measurements (by playing a tone and measuring with a multimeter) I found that if I plug a male to male 3.5mm jack to the headphone, it will play audio thru, however none of the settings for headphone will be enabled (meaning that the phone doesn't think that I'm using headphones) if I then connect headphones using an adapter it will play at full volume no problem.

The 3.5mm2 jack puts out 0.8Vrms when there is no headphone, and 0.25 Vrms when it detects headphones. (way too low for many headphones).

This means that the phone has a feature that lowers its max volume by 10 dB when using headphones, that is why it also affects bluetooth audio.

For those that want to test it, if you plug a 3.5mm2 extension cord to the headphone jack, and then you plug headphones you will find out that the max volume is much much louder.

Hopefully there is a way that I can remove that feature all together.

I already tried changing the region, disable absolute volume, etc. None of that worked.
[Redmi 9 Power / 9T] SamueruSama:
Follow up:

I found that what causes the problem is the equalizer effect that Xiaomi added to the phone.

Every time that the smartphone detects headphones it enables the equalizer, the equalizer has a range of +10dB and -10dB.

They implemented the EQ in such terrible way that +10 dB is actually -10 dBFS and -10 dB is -20 dBFS.

So if I increase the volume at say 100 Hz, it is now able to output 0.8 Vrms at 100 Hz. However if I increase the volume in all bands the EQ does nothing and it stays at -10 dBFS. meaning the issue is still present.

There is no option to disable the EQ, it is just flat by default but they didn't add an option to turn it off.

Edit: I tried disabling com.miui.audioeffect thru ADB and while it was disabled, the volume is still low.

No idea if there is another APK that I could try.

[Samsung Galaxy S21 Ultra] zpunout:
Does the USB-C to 3.5mm dongle have a DAC converter chip inside? Some phones don't output analog audio natively through the USB-C port and require a digital to analog conversion which are supported by some external adaptors. Maybe that model device doesn't output analog audio via the USB-C?
[Samsung Galaxy S21 Ultra] amirage:
Yes, this is the correct answer to the OP's question. You need a DAC USB-C not a simple USB-C to 3.5mm adapter. Such adapters retail for around $50+ the better the DAC the higher the price.

Just bought a 32bit/384kHz sampling one for 8$ on Aliexpress...and before you tell me I can't hear difference between this and a 16bit one...let me tell you..I DO.

I got a 3$ DAC onw and while good for calls, I can definitely tell the difference for music.

And yes, I have the Huawei adapter that came with a Mate 20 Pro ( remember the times when power adapters,cables and 2.5mm jack converters came with phones???) and it's not recognized by the S21U.

[Samsung Galaxy S21 Ultra] raudszus:
you need one with a DAC
[Samsung Galaxy S21 Ultra] amirage:
You will surely hear the difference between a 16bit and 32bit sampling. It's very likely Huawei adapter may not have a DAC on board as my OnePlus 7Pro adapter didn't have one. My contention was not about the price - $50 for a DAC adapter. The point I was trying to make was that you needed an adapter with a DAC..the better the DAC onboard the better your music will sound. It's all personal taste...and if an $8 DAC does the job...good for you!
[Samsung Galaxy S21 Ultra] zpunout:
One day, in the future, phone technology will be so advanced that they will have DAC built in.
[Samsung Galaxy S21 Ultra] diffidatipk:
use the OEM from samsung ... i did buy a couple with the option to charge at the same time and they didn't work. Saddly you need a one with build-in DAC onto the Type-C to 3.5mm adapter. The cheapest one is the OEM from samsung.... sucks but thats it.

Ok.. after getting ticked off with "some application" resetting my backlight timeouts, I've been able to track it down..

for some reason the HTC home applicaion (when enabled on the home screen) will reset the backlight timeouts and set them to values of 8s (on batt) and 120s (on power).

if you change them yourself, it will work fine until you make the phone suspend (tap the power button).. when you unsuspend, the HTC home App will change the values back to 8/120.

AARRRGGHH and of cource HTC's answer was.. we don't support registry changes.. just don't use the HTC home application..

guess it's time to break out the code and build my own pluging for suspending and double restore them after the HTC home app changes them..

[Samsung Galaxy S9+ Questions & Answers] Trism:
My boss recently acquired an S9+ and wanted to factory reset it maker sure it was clean before usage. Being 'the tech guy' it's been handed over to me to sort out. However there's something very weird with this phone. There's no Play Store, for a start. It's not disabled in the App settings, it's just not there at all. I tried installing an APK of the latest version, it installs and acts like it's updating an existing app, but when I try and launch the program is says there isn't an app installed to perform that operation.

I decided to just wipe the thing and start from scratch, but there's no option anywhere to perform a factory reset. NOTHING. No options in the settings and nothing in recovery (photo added for proof).

So I've decided to adopt a scorched earth policy and root the thing and install a fresh vanilla ROM. Except I CAN'T because I can't enable OEM unlocking. I've gotten into Developer option no problem, and OEM unlocking is there. I toggle the switch, press enable, press the blue Delete All button and... nothing. Well, not quite. Very briefly a box will pop up that bottom saying Reset but will disappear immediately. I'm utterly stumped!

Does anyone have any suggestions?

[Samsung Galaxy S9+ Questions & Answers] Trism:

Spoiler content hidden.
[Samsung Galaxy S9+ Questions & Answers] spawnlives:
It's the right screen

Did you use recovery to boot into download mode or did you use the power/vol down/bixby buttons when booting phone.

Also when you flashed the phone with stock firmware did you do a clean install. ie: used the csc file.

and did you boss say if it's a new or second hand phone.
[Samsung Galaxy S9+ Questions & Answers] Trism:
It's very much second hand. And I think I've partially solved the problem.

I did a full reinstall using Odin and did a Nand wipe in the process. This finally made an actually full reset of the phone as it took me through the setup process. However, it automatically install a Knox profile that locks it into Retail Mode, so I guess this is an ex-display unit.

My new issue is getting out of Retail Mode. If I open the app for that it makes me choose which store the phone came from, then it downloads a 9GB file that sets up the display demo. I've found the passcode (5444) to get into the Retail Mode app, however once it begins working it completely disables the keyboard, so I can't go back into the app to disable it again. Its all very annoying.

*EDIT* Well, I got around that and disabled Retailed Mode.... and the original problems are still there. No Play Store, no Factory Reset options, can't unlock OEM.

I have now actually found that the Play Store is installed on the device, but it's disabled and pressing Enable does nothing. I'm totally stumped.

Here's the shot of the download mode screen you asked for. No idea if it will help now, but I'm willing to try anything.

Spoiler content hidden.
[Samsung Galaxy S9+ Questions & Answers] spawnlives:
I don' know to much about the retail mode except for the option in developer menu. I have never tried to turn it on/off.

Amonst other things from your download screen your OEM ( bootloader ) is on. Miight be because of the retail mode.

In regards to trying to enable play store maybe try using adb to enable it.

While l could be wrong i was iniatally thinking about some sort of MDM lock which will prevent you from doing stuff to your phone.
[Samsung Galaxy S9+ Questions & Answers] Trism:
Hm, I didn't know you could enable things like that through ABD. I'll look into that, thank you.

*EDIT* Holy crap that actually did it! I uninstalled then reinstalled Play Store through ADB and it's now enabled! Thank you, dude. I really appreciate your help!
[Samsung Galaxy S9+ Questions & Answers] spawnlives:
So can you download, use apps from playstore.
[Samsung Galaxy S9+ Questions & Answers] Trism:
Yep. Still can't factory reset, but the Play Store is working as expected. Installed a few things and reloaded several times. Everything is still there.
[Samsung Galaxy S9+ Questions & Answers] Cr0magn0n:
@Trism you literally saved my life, I had the same issue and resolved throug adb. Still disapperared the reset functions.

Other than the Wear Os app the Galaxy wearables app does not see work profile apps and will not push their notifications. Let's see if that gets fixed at some point.

I think this is another "only works on Samsung" thing.

I had this problem on my oneplus phone. Switched to a Samsung and it was working fine. (that was the experience I had on previous generation wear os and Tizen watches at least)
[Samsung Galaxy Watch 4] diabloazul126:
Yeah, it'd be nice if there was some sort of workaround for this. Even just as simple as bridging notifications without allowing actions on the Watch would be more useful than the current lack of anything.

It's also sort of odd, looking at the notification settings in the Wearable app shows that it does see that there was a notification coming from that app (gmail, calendar, etc.) even if it was a work profile notification, but won't allow the work profile apps to be synced on anything other than a samsung phone. :(
[Samsung Galaxy Watch 4] esudip:
Yes I observers the same, I tried to bridge the notification by some apps but not working, You got any luck with Bridging? Also DUO Mobile app was working awesome with Andriod OS 2, But it isn't working here... Looks like Tizen thing is preventing it.

All Work profile apps and Duo Mobile had been se to "Off" by default. I've turned them on. We'll see how it goes...

{ETA: Success! Duo (via personal) and Slack (via Work) are sending notifications to the watch! I can't act on Duo except via the Phone, though, so not sure how useful that part actually is.}

Hello guys,

I am planning to buy S21 Ultra, after reading some older reviews and watching some videos I was wondering if I should get snapdragon (according to some reviews a better one) version or exynos? I am based in Europe.

Is there still big difference (or any) in performance, camera and battery?

Also, will there be any problems using snapdragon version in EU?
[Samsung Galaxy S21 Ultra] MAX 404:
Hi

There are not such a big difference in performance ( that you can really notice in your daily use) to say one is better than the other

You can root both but exynos is "easier", if you live in europe the exynos may be a better option , there is no european firmware for the SD , even though both firmware should work fine , the snapdragon firmware may be a little more limited as 4G and 5G bands are not all the same and maybe an specific carrier service may not be available due to the CSC

I'm going in...and have committed to Google's Newest (for now) offering, mainly, due to my ADHD/OCD advisement and my current Pixel is pretty much taken care of thanks to the

platform offered by our great allies @ SWAPPA!

Given the purported IP67 rating & considerably larger power-source over the 4a(5G), I'm fully aware of the fact these two handsets are damn near twins, I decided not long ago I wouldn't be a Pixel 6 taker(when/if offered this fall).

As always, comments, opinions, and yes, even some fun ridicule are always welcomed!😭

Stay clear of the delta variant, & safe journeys!
[Google Pixel 4a 5G Guides, News, & Discussion] bubbyj:
To each their own.

But I can't force myself to pay $450 for an 18% larger battery. Considering that my current rooted Pixel with custom rom and excellent tuning will last through the entire day 100% of the time. The 15% brighter screen, coupled with 1/4" larger size, and 65,000 more pixels, and a 50% faster refresh -- will absolutely cancel out any increase in battery size, and then some. Its SOT time will suffer considerably, and almost certainly be worse than 4a 5g. Then there's the 30w charging. Supposedly the Pixel 4a 5g tops out at 18w. But this is demonstrably false. My own charging maxes out at nearly 27w. 9v @ 2850mah. So again, this is of zero benefit. The 10% faster charge rate would still require about 10% longer to charge with the larger battery... that again, would likely discharge at a much faster rate than the 4a 5g. IP67 is nice, but again... its not worth $400. Especially considering that I can literally throw my current Pixel 4a 5g into the ocean... twice... and just buy 'new' ones for less money. :-/

I mean, if it had the new Tensor cpu... and a ultra premium camera, rather than the same 12.2mp thats been in it for the last 4 years. Some cool new features like under display front camera and fingerprint.

But its literally the same effin phone. Google is now following the same identical business model as Apple. Upgrades that aren't -- well... upgrades.

The biggest change between the 4a and 5a? the 4 and the 5 in the model number. Its disgusting to me.

Do you really not have anything better to spend your $450 on?? I mean, thats a years worth of car insurance. Or 2 car payments. Or Rent. Or 6 escort services. Or a weekend in Vegas. Or 4 pixel 4a 5g's off craigslist that youd set on fire and record it in 4k while playing Freebird in the background.
