Samsung Galaxy Tab 4 8"

I want to start a thread on this device. I just got it and there is no thread specific to this device. I was able to root it with ODEN - but there is no TWRP recovery yet that I have found. This device has MHL capability unlike the 7" device. I had the 7" device but returned it for the 8" to get the MHL capability and it also has more memory. Hopefully, if people start looking at this thread we can get stuff going for this device.

I've got the black version. While I'd like to sell it and get a Tab S, I realize the Tab4 is plenty fast, especially after rooting, and using seeder and trickster mod to tweak.
It seems we have a lot of owners, but no coders

Mines actually black too. I have to check out the seeder and trickster mod - is there a thread on it?

Would like to find out more too please.

Trickster mod is available on playstore.
Seeder is in a thread here on xda, I'd link but I'm on mobile.

Does anyone know of a link that discusses Clockworkmod progress for a recovery for this device? I saw a link somewhere but it was dead. - so I could not read it. Something they were having problems on recovery for this device - but I could not even link so that may be wrong.

Just got mine yesterday, great little device . Looking forward to TWRP and CyanogenMod though

Just spreading the love,
Seeder

Would like to use this for my Tab 4 8" but it looks like it requires S-OFF - I thought that was for HTC devices.

Read my post above, I have both on my 8" - they only require root access.
That link for Seeder is from the HTC Sensation section. Follow the links in the Credits list the first post

Also, check out using Xposed and Install the Wanam Xposed module. Lots of TW mods.

Yeah.. I tried and it didn't. I have been busy fighting Samsung through their US headquarters to get what they've promised with the product.. Which they have promptly removed from their website only after two Official filed complaints.

Anyone want to build a recovery for the 8"? It seems like nobody cares about the T330...

I'm currently working with a couple developers to attempt building twrp for it but they keep saying without kernel source code, it'll be buggy. Of course the 8" is the only tab 4 Sammy hasn't released kernel for.

It appears to be on opensource.Samsung.com, or is that not the correct source needed?

You got that page to load? Won't load on any device for me, android or Windows. If so and it's the kernel for the 33x, please download it.

I'm unable to get it to download on my tablet with any browser. It doesn't state specifically that it's kernel source, just:
Classification: Mobile Phone
Model: SM-T330NU_NA
Version: T330NUUEU0ANC3
Source Code: SM-T330NU_NA_KK_Opensource.zip
If someone could get this to download I think this is what we need.

Release/Download: https://github.com/james34602/JamesDSPManager/releases
If you look at the source code from Java part, you will find some are similar with Viper4Android, but this is not true.
Viper4Android only open source it's interface, their core drivers source code have never been released.
For convenient sake, I copy some interface code to accelerate my development.
How to compile the source code?
Use eclipse && Android NDK will do the job.

This guy are cool! They have tested to use JDSP with v4a! https://forum.xda-developers.com/apps/magisk/module-jamesdspmanager-2017-10-15-v1-1-t3689390

I reach my milestone and made 14 Band Equalizer works @ 32, 64, 126, 200, 317, 502, 796, 1260, 2000, 3170, 5020, 7960, 13500 and 15000 Hz
And more nice bass filters

I have done more on optimize the audio engine, it use less and less CPU usage than before.
So far I have update:
Pure stereo widening.
Reduce band number to 12 bands.

great! this is purely cpu based? can it be hardware accelerated for less CPU utilization?
also a flashable zip would be nice

Tunnel player?
james3460297 , looks very promising. would this bypass the tunnel player that most Samsung phones use allowing for audio visualizers to work?

@james3460297 ... any plan to support magisk module for this ... seems promising. thanks for the works :good:

It looks like it works fine on my phone (MT6755, ARM64, Android 7.0) without any additional steps. I just flashed JamesDSPManager-v1.5-HQ-Auto.zip via TWRP recovery. I didn't remove anything or do other things.

James, would it be possible to add a parametric EQ where users can add custom frequencies and Q factor.
There is no parametric EQ on Android that works systemwide, i hope yours will.

4k video shooting

Do you also have 4k video in your camera app after nougat update?But it does not work for me . It says that the SD card is not available.

I don't have it in the sony camera app.

Do you have SD card? Do you have a lot of free space? 4K videos take a lot of memory.

Nope, don't have it. Not in the settings and not in that camera applications thing. I have a 64GB SD-card optimized for 4k video shooting (high sequential write speed), so that should not be a problem.

Hm that is weird. Try searching for latest camera add-ons (in your case 4K) on apkmirror or if it is updated, try removing update. I had problem on my old phone with timeshift burst. When I update add-on and start it I get camera crash, but when I uninstall update (I think in options it said something like "Do you want to replace this app with the factory version?") timeshift burst works perfect.

I don't have that but I just got a xperia tip notification that says "enable double tap to wake". When I touch "take me there" it can't find the related menu of course.

Both 4k and dttw need hardware support.
According to this page about the xa's soc, 4k support is absent.
And since they did not add dttw in previous firmwares, I'm guessing this is not supported either.

As far as I know, dt2w must be supported by kernel not the hardware.

I guess the hardware should provide the possibility to enable touch without enabling display.
With oled screens this doesn't matter, as a black screen uses (almost) no power, but leaving a lcd display on is wasteful.
Of course, kernel support is necessary on top of hardware support.
(Correct me if I'm wrong, I certainly don't claim to be an expert on any of this)

I'm not an Android expert too but in Windows Phone, my Lumia 630 has standard IPS display (no OLED) what I needed to enable dt2w was adding a simple registry key (NT kernel supports dt2w regardless of device but for some reason, Nokia decided to disable it on cheap WP devices).
Also my old Ace 2 used to support dt2w with custom kernel on cm10 or 11 I can't remember exactly (it has standard LCD display)
On both of these devices battery consumption didn't change after dt2w.

I'm not an Android expert too but dt2w is based on kernel feature and use the digitizer to work, OLED or LCD is not the problem. As you probably know I enabled F2FS feature on my XA, the question is the same: why Sony didn't use it out of the box?
For me the answer is because a mid-range device must stay a mid-range device and costumers must have the illusion that there is a big difference with flagship devices.

Yup 4K is not going to be available even with newer updates since Mediatek MT6755 Helio P10 supports up to 1080p 30fps H.264 on video encoding.

Xiaomi Mi Mix 2s bad audio quality recording video

Unfortunatly The Mix 2s seems to have very, very bad audio recording quality.
See the review of TechTablets:
https://www.youtube.com/watch?v=HLbYuLW7gbw
What I don't understand, the issue of bad audio quality is there for many Xiaomi devices.
Is then no-one testing this at Xiaomi ? These bad reviews will have negative impact on sales.
And most of the time the fix is easy.
The Mix 2 also suffers from the same issue:
]http://en.miui.com/thread-1730106-1-1.html
And same issue for Mi Max 2: http://en.miui.com/thread-730427-1-1.html
Some suggested workarounds, hopefully they also work on the Mix 2s:
- https://www.reddit.com/r/Xiaomi/comments/6zbper/mi_max_2_workaround_for_noise_cancellation_mess/
- https://www.reddit.com/r/Xiaomi/comments/6txqjt/i_discovered_something_about_the_mi_max_2s_poor/
- http://en.miui.com/thread-965057-1-1.html
Hopefully Xiami will fix this very soon, it will bring them more sales i think.
Anyone any ideas on how to fix this on the Mix 2s ? (hope to receive mine in 2 weeks )

I think if you sell a phone so much cheaper than other companys you have to make the cut somewhere... If they use a mic that costs 2$ more in production it's already 200000$ if they produce 100000 units

This is a deal breaker for me, as I mainly record videos...
Too bad I was about to buy it in China next week...

I really hope it can be fixed with a software update... the mic quality sounds poor and I was let down since I regularly call. Overall the phone ticks everything I want.

One substitution I discovered is to use Open Camera App. In video setting, select 'default audio source' in audio source option and 'stereo' in audio source channel option. I tried this setting on my Mi Mix 2s MIUI 9 and it works so much better than the default camera app.

I've read about people trying to fix this problem in the same way with the Mi Mix 2 but it didn't work at the time. A comparison between the two input sources would be great to understand better the difference. Thanks.

Huge difference,
Currently use open camera in my OnePlus One ...and waiting for Mix 2S to arrive in ~10 days, so I guess I'll keep using open camera

Anyone know if the poor audio quality when recording videos is fixed in the MIUI 10 beta?

So this is a software bug for sure?

I dont have issue's anymore i am on 8.8.16 (Miui 10/Android 9) rom which at the moment is still in closed beta.

Hi I have made a comparison with my other phone (samsung note 9). Surprisingly, the mix2s sounds better. Running MIUI 10 Stable Global.

Hello,
I would like to draw on the subject, I can confirm the same problem with MI A2.
I came to the solution using Open Camera:
audio source: external mic
audio channel: mono
I've tried the solutions described in this topic, but without success and then I accidentally found a pretty good solution.
Greetings from Croatia

[Magisk] [Module] STEREO-HIFI-PREMIUM to AOSP 9.0

STEREO-HIFI-PREMIUM only for AOSP 9.0.
Author Big_Brazer , I just tested and made it a module for Magisk.
This is not a port , the mod is made entirely on the aosp 9.0 files of our device.
Not to be confused with the stereo mod for two speakers, this is not about it.
*
v1.4
The sampling frequency of the audio is increased to 862000hz
Audio frequency up to 32bit
The Bluetooth A2DP driver now has support for 128bit 768000hz.
Improved effects surround_sound the back of the stage and improved audio depth.
===
v1.5
Activated Auro 11.1
*
It is recommended to install on a clean system without any audio modifications in the form of Dolby, ViPER4Android and others because they still cut the quality of the signal under its configuration.
P.S. perhaps they you more not will need.

How to check if it's working ???

v1.5
Activated Auro 11.1

For what is this mod ? I just edit mixer paths to 92 lvl instead of 72 and sounds wonderful .
