You have something wrong in your tablet, I guess, at firmware/partitions level. Restart from scratch by flashing stock lollipop with pit file. Bluetooth is working at 99% of cases, but in case bluetooth address is lost, I let the guide on how to recover it. I'm not sure if the issue is definetely fixed because I've never found the reason why it happened and, in case, how I fixed it.
[Galaxy Tab 4 Original Android Development] metalshreds:
I just spent too much time with the same problem, multiple clean installs and "free up space" with no apps listed every time. Did you by any chance nuke the whole stock folder structure/ wipe internal memory?

I had to flash the stock firmware again 5.1.1 which kept crashing at boot but still created the stock android folder structure in the internal memory, then I flashed TWRP using odin and LOS 18.1 and opengapps nano and finally was able to install apps after a clean install

Ohh one other thing, "system gesture navigation" seems to be missing completely from the device. No way to get swipe left or right for back button.
[Galaxy Tab 4 Original Android Development] VoluntaryMan:
That is exactly what I did. I'll try that, thanks.

EDIT: yes, this fixed my issue
[Galaxy Tab 4 Original Android Development] matteo0026:
Since we have physical buttons, navbar and gestures are disabled. To enable them, write qemu.hw.mainkeys=0 at the end of /system/build.prop file.

Worked great! thank you!
[Galaxy Tab 4 Original Android Development] matteo0026:
Hi guys, new builds of LOS18.1 are online.

Changelog:

- October 2021 security patches

Keep in mind that from this build, if you want to check the integrity of the zip file, now the checksum file doesn't have the .md5 extension, but .sha256sum.
[Galaxy Tab 4 Original Android Development] matteo0026:
I have to correct myself. I removed the link to mega to download the sha256sum file because now AFH supports that format of file. So, you'll find both zip and checksum files in AFH!
[Galaxy Tab 4 Original Android Development] Ozbargain22:
I'm also having the same issue. Re-installed Lollipop stock but stuck in boot. So you just re-installed TWRP and lineage and it worked?
[Galaxy Tab 4 Original Android Development] VoluntaryMan:
I think what you are doing is wiping partitions before installing Lineage.

Don't do that.

Just lollipop, twrp, lineage (then wipe ONLY data/cache).
[Galaxy Tab 4 Original Android Development] matteo0026:
What? No, don't do that. System should be wiped by coming from other ROMs, to do a clean installation. It always worked. Instead, check TWRP version, that could be fatal if not well updated.
[Galaxy Tab 4 Original Android Development] Ozbargain22:
I used the TWRP from this guide. Lineage hangs each time so I flash stock again. Stock then hangs.
[Galaxy Tab 4 Original Android Development] matteo0026:
It could be a partitions issue too, so I advice you to flash 4 parts stock firmware, with pit file too
[Galaxy Tab 4 Original Android Development] Ozbargain22:
Do you have the links to these please?
[Galaxy Tab 4 Original Android Development] Achsel:
The automatic rotation suddenly no longer works on my Tab 4 10.1" WiFi (SM-T530). Therefore I would like to recalibrate the G-Sensor. With Android 4.4 / 5.0 you could use the calculator app to enter the code (+30012012732+ and then you could enter the code *#0*# into the large keypad that appears to get to the service menu. This does not work with the LineageOS 18.1 calculator app. How can I get to the service menu?

PS: The "GPS Status" app also offers the option to calibrate the G-Sensor, but it did not work. Maybe the sensor is defective.
[Galaxy Tab 4 Original Android Development] Achsel:
After I restored the last backup from the system via TWRP, the automatic rotation works again. I suspect that an update from the "CovPass" app, which can only be displayed in portrait format, destroyed the calibration data for the sensor. Deleting the app wasn't enough either. In TWRP I first deleted "Dalvik / ART Cache", "System", "Data" and "Internal Storage" under "Advanced Wipe", then executed "Format Data" under "Wipe" and only then I selected and installed the backup under "Restore" from the micro SD Card.

I will no longer install the "CovPass" app on Tab 4. There are no problems with this app on the S4 phone. I installed the October update of LineageOS. According to the "GPS Status" app, the Tab 4 does not have a gyroscope sensor, but only an acceleration sensor, which is now working again.

PS: Does anyone know in which file and where the values for the calibration of the sensor are saved?
[Galaxy Tab 4 Original Android Development] matteo0026:
Rotation should work fine. Service menu is samsung proprietary, so you just can get the secrets menu of AOSP.

About this last ask, I don't know how to help you. By the way, I think that CovPass and other sensitive data apps should be installed just in recent and with locked bootloader devices.
[Galaxy Tab 4 Original Android Development] Jurgie:
Sorry big noob here but I'm having weird issues. I just got the ROM installed on my SM-T535 using TWRP but none of the apps seem to work properly. I tried downloading f-droid with the default browser but the browser crashes as soon as I hit 'download'. A lot of apps open but crash as soon as I try using any features. Apps like music and camera do not open at all and crash straight away. Wi-fi works fine but can only use 2.4GHz.

Again I'm a noob so I have no idea what causes these problems... Should I try to re-install? What could be causing these problems?
[Galaxy Tab 4 Original Android Development] Achsel:
@matteo0026

Thanks for your answer!

To be on the safe side, I copied and backed up all the files that I could find in connection with the sensors on the external memory card. Here are the paths to the files:

/data/system/sensor_service/hmac_key

/persist/sensors/sensors_settings (contains only the number "1")

/system/bin/sensorservice

/system/etc/sap.conf (sensor settings)

/system/lib/android.hardware.sensors@1.0.so

/system/lib/android.hardware.sensors@2.0.so

/system/lib/android.hardware.sensors@2.1.so

/system/lib/libsensor.so

/system/lib/libsensorprivacy.so

/system/lib/libsensorservice.so

/system/lib/libsensorservicehidl.so

/vendor/etc/sensors/_hals.conf

/vendor/lib/hw/sensors.msm8226.so

/vendor/lib/hw/sensors.vendor.msm8226.so

Due to the unusual name, I only discovered by chance that the "sap.conf" file contains the sensor settings.
[Galaxy Tab 4 Original Android Development] matteo0026:
I think the best thing is to clean up everything by flashing stock firmware and then reinstalling everything from scratch.

Some files you wrote are built by the ROM environment, the other files are coming from device/vendor source. They should be ok, since they come from samsung msm8974 (as that sap.conf file) or galaxy s3 neo (as the blobs mentioned at the end).
[Galaxy Tab 4 Original Android Development] Achsel:
I suspect that the last update for the "CovPass" app damaged the "sap.conf" file and caused the sensors to no longer work. After restoring the complete system backup, the automatic rotation works again. The test with the "GPS Status" app no longer shows an error for the acceleration sensor. For emergencies I now have a backup of the "sap.conf" file.
[Galaxy Tab 4 Original Android Development] Jonae:
Thanks for the great ROM. It works like charm!

Hi guys, new builds of LOS 18.1 are online!

Changelog:

- November 2021 security patches

- Encryption now should work (change tested on S3 Neo) ~ I want to add here that it slows a lot down the device, you're warned!

- Fixed WPA2/WPA3 co-existance (in this way, you can connect to a Wi-Fi network set with WPA2/WPA3 security key, instead of only WPA/WPA2)

- Some other more specific things under the hood

And with this post, I say goodbye to my main smartphone, Galaxy A52 5G. I still didn't choose the new one. Why should it be that hard to choose one? :(
[Galaxy Tab 4 Original Android Development] matteo0026:

[Galaxy Tab 4 Original Android Development] Jr_Ferreira:
Hi,

Greetings from Brazil.

Great ROM but I believe I did something wrong during the install.

I have a SM-T531 and in Brazil android only went up to Android 4.4.2 KitKat for this device. As I was watching a tutorial from youtube, I didn't check the minimal requirements for the process. After some problems, I got here and I notice I should have the latest Android Lollipop 5.0.2 for matisse on my device, but I had already finished all the procedures with the bult-in android 4.4.2.

After the install of the GApps ( the last procedure ) the tablet should reboot and then start the booting after a while, correct? But it freezes on the Samsung Galaxy Tab 4 screen and It doesn't boot up. The funny part is that I didn't get any error messagens in any part of the install, everything went ok the whole time.

These are the files I used for the process.

twrp-3.5.2_9-0-matisse

lineage-18.1-20211107-UNOFFICIAL-matisse3g

open_gapps-arm-11.0-pico-20211120

Could you help with what I should do next to install Android 11? ( Could also be android 9 or 10 )

Thanks in advance for the help and keep up the excellent work.
[Galaxy Tab 4 Original Android Development] matteo0026:
That's why your tablet stays in the bootlogo when you try to boot LOS. So, since in Brazil Lollipop has never been released, flash the firmware of another country based on Lollipop. It doesn't create any issues.
[Galaxy Tab 4 Original Android Development] Spontaneous:
I dont know if I did something wrong or what the deal is. It flashed fine and I think I am stuck on the first boot. It has the frown like line and the bubble going from right to left, but its been some time and it just stays at this screen. Edit: NM I got it working

BUT

New problem, wont let me past the SIM card missing screen. This is a wifi only (sm-t530nu) model.

Again, figured it out. Doesnt show the next button in landscape but does when I rotate screen.

The problems keep rolling but this one I have not figured out.

I got MindTheGapps installed. I goto install other apps using the Google Play Store, BUT it says I dont have enough storage???? I check settings and I only have 23% of the 16gb of storage used so PLENTY of space. Is there something I am missing?
[Galaxy Tab 4 Original Android Development] cali.s:
Works great, thank you for your work (y)
[Galaxy Tab 4 Original Android Development] ThetaProtocol:
First off, I'm grateful you're putting these out, I've found a load of these for some extended family and would rather them not have to deal with kitkat, so I'm running through all the ROMs you've put out.

I've got a couple of mattise wifi tab 4's sm-t530nu.

I honestly thought LineageOS would work the best but its the slowest of the two that work. Granted the only testing I did was flash a rom, scroll around the launcher, test the camera and open YouTube, but the lineage-18.1-20211107-UNOFFICIAL-matissewifi build was noticeably more sluggish, especially loading websites and loading YouTube thumbnails. Scrolling between app drawer and switching apps felt pretty bad too. Now I had thought that was just the hardware but your CipherOS build is working like a champ on on the same apps as the lineage build was doing everything far more snappy than a 2015 tablet has any right to be. If you need logs or anything, I'd be happy to attach if you can tell me how.
[Galaxy Tab 4 Original Android Development] matteo0026:
CipherOS is lighter than LOS, since it's very essential. And I can't do anything more, performance side. Understand that the tab 4 is 7 years old, and it isn't that powerful. If you try LOS 16, situation improves
[Galaxy Tab 4 Original Android Development] jsjxu:
hi, I put lineage 18.1 android 11 on a 530 tablet (fiwi) and open gapps, it worked fine for half a day, then after rebooting this error came out on the Samsung " set warranty bit kernel" label and does not load into the system, in the recovery comes in
[Galaxy Tab 4 Original Android Development] matteo0026:
Reflash the ROM in a clean way. The phrase "set warranty bit: kernel" is just a warning because you installed an unofficial software. Nothing to worry about.
[Galaxy Tab 4 Original Android Development] jsjxu:
so it is not included, the process does not go further than this inscription. Everything worked yesterday.

[Galaxy Tab 4 Original Android Development] matteo0026:
Don't use the format data button. Select the 4 partitions I've told many times (dalvik/art cache, system, cache and data) in advanced wipe. Otherwise you won't wipe system, and that's needed to do a clean installation.

Hi guys,

I just got the TAB a6 smt 580 and when I open the case I've bought for it, the screen lights on automatically. And when I face the tablet down it turns off. Is there anyway to disable this? This is really anoying because sometimes when I can't sleep I like to put on a silly show on netflix, face the tablet down so I won't see the light from the screen but still can hear the sound and just try to go back to sleep...but when I face the tablet down the screen turns off.

[Google Pixel 4a Questions & Answers] iamagro:
The Pixel 4a has this DAC, which as you can see is a great DAC, its specs are even better than many HIFI portable audio players. Well, for the uninitiated, android acts as a bottleneck in this case, as it always limits the audio output to 16bit 48khz (using a low quality resampler for the benefit of performance)

Is there any way I can use it decently? Because Google apparently has no intention of doing anything, it hasn't even shared any information on how to use the DAC, and I don't like the idea of having to use an external dac even though the 4a has a headphone jack.
[Google Pixel 4a Questions & Answers] Makishima:
I'd like to know too. Doesn't Viper4Android help get more out of it? I'm getting pretty great sound with that + PowerAmp.
[Google Pixel 4a Questions & Answers] iamagro:
mmm I need to know how you set the audio settings, the output audio is resampled to 48khz? have you set the output in HD?
[Google Pixel 4a Questions & Answers] Makishima:
You mean my settings in PowerAmp or Viper?
[Google Pixel 4a Questions & Answers] .: SID :.:
Yeah.. It seems that Hi-res potential is not implemented in the stock ROM. Everything is mixed into 48 kHz...
[Google Pixel 4a Questions & Answers] Makishima:
I see. Is there any custom Rom that implements it?
[Google Pixel 4a Questions & Answers] Makishima:
Also, have you tried Ainur Narsil? Perhaps it does what you want. I'm just unsure whether it will work on Android 11, it seems development is paused.
[Google Pixel 4a Questions & Answers] .: SID :.:
I'm not aware of any custom ROM which supports hi-res. If you know, please tell. 😉

I've tried ainur but without success. And smth was even corrupted because sound became worse.

Mary be community should raise an issue for Google.
[Google Pixel 4a Questions & Answers] Makishima:
I've no idea actually. I'm interested in this stuff, but not so much as to notice worse quality with the 48khz Android output. And yeah, that's why I haven't tried Narsil, it doesn't seem to be too well tested in A11 and we don't even have a proper TWRP in case something goes wrong. Still, I am noticing a difference with my modded Sony NW-A45, but it's not like it sounds better, it sounds different perhaps.
[Google Pixel 4a Questions & Answers] Yeedatoy:
Poweramp is terrible. You need an app that bypasses androids software. Usb audio player pro is the best available. It plays bitperfect audio. Neutron is second, it can also play bitperfect audio. Both apps can output 32bit/364kz at whatever rate the Track allows. Uapp plays MQA as well

Hi,

I've seen a strange logo in the "slide bar" of TF3D of the Touch HD (you, know the "bar" you touch to change to email, contacts, etc. It looks like a Stock Quotes logo. Such a thing in TF3D could be great. See your stocks gowing down and down in the same way you see the rain coming to you in the weather tab.. Wow ;-)

Does some of you heard about such a thing?

Soo I recently Had a problem explained here

https://xdaforums.com/t/help-i-form...tloader-is-locked-and-i-have-no-imei.4271955/

And I found a fix

Requirements--

1) Mtk-SU Easy https://github.com/JunioJsv/mtk-easy-su

2) This Version of MIUI

Redmi 6 https://bigota.d.miui.com/V11.0.2.0...XM_20200102.0000.00_9.0_global_5bc2bc0cf8.tgz

3) A backup of your NVDATA or any IMEI changing app I don't really know the rules here about such apps soo do a little bit of googling (NOTE:DONT CHANGE IMEI ONLY PUT THE ORIGINAL IMEI OF YOU DEVICE)

4)SP-Flash Tool

ONE THING IF YOU HAVE UNLOCKED BL JUST GO AHEAD AND GET MAJISK AND USE IMEI RECOVERY APPS WITH ROOT

Let's Begin(UNLOCKED BOOTLOADER PEOPLE JUST USE FASTBOOT AND ON PC OPEN flashall.bat which is inside the folder once extracted then continue from step 2)

1) Flash the above version MIUI using SPFLASH TOOL

2) Setup the phone with NO INTERNET after setup connect to internet

3) Download and install the mtksu easy app latest version also install majisk manager 8.07

4)Open the mtksueasy app and click on the hash button to get root

5) After that go ahead and install either root explorer or IMEI changing app

6)

For people having NVDATA backup (if from twrp extract using https://play.google.com/store/apps/details?id=ma.mk.twrpbackupextractor)

After that install Root Explorer and give it root preveleges. Then open /vendor/nvdata/

There copy all stuff inside and keep inside a folder as safety then go ahead and delete it all from /vendor/nvdata (mount it as r/w) next go ahead and paste all stuff from your NVDATA BACKUP INTO THE FOLDER. Then reboot.

For people who are using IMEI CHANGER APP just go ahead and type your original imei (Get it from the box)

7) Your done actually u can now unlock bootloader.

[General Questions and Answers] MrNice:
Hi there,

I am a newbie with Android and smart phones.

As an old-school tech, from Windows 3.0 to Gnu/Linux, I want for long time avoid all GAFAM stuff and keep a bit of privacy and security.

I came across the Exodus site and try to find app with zero tracker and minimum permission.

Do you care about that?

Do you use FOSS apps?

Do you have a list of usual apps that fulfill your need AND privacy?

Any help, advise, list of apps (browser, messaging, files management, maintenance, ...) are welcome.

Thank you
[General Questions and Answers] Deleted member 1890170:
IMHO it doesn't matter where you fetch apps from: F-Droid, Google Play Store, etc.pp.

Apps typically request normal premissions and dangerous permissoins.

Dangerous persmissions are

READ_CALENDAR

WRITE_CALENDAR

CAMERA

READ_CONTACTS

WRITE_CONTACTS

GET_ACCOUNTS

ACCESS_FINE_LOCATION

ACCESS_COARSE_LOCATION

RECORD_AUDIO

READ_PHONE_STATE

READ_PHONE_NUMBERS

CALL_PHONE

ANSWER_PHONE_CALLS

READ_CALL_LOG

WRITE_CALL_LOG

ADD_VOICEMAIL

USE_SIP

PROCESS_OUTGOING_CALLS

BODY_SENSORS

SEND_SMS

RECEIVE_SMS

READ_SMS

RECEIVE_WAP_PUSH

RECEIVE_MMS

READ_EXTERNAL_STORAGE

WRITE_EXTERNAL_STORAGE

and only become activated if user clicks ALLOW to them: so it's on user what permissions can be used by an app.

So-called normal permissions get allowed by default without any user interaction.
[General Questions and Answers] MrNice:
I you sure only normal permissions get allowed by default without any user interaction? and where can I separately allow or deny them? Is there a place where all these permissions are explained and what I'll block in the app when denied?

What about tracker? Is it possible to deactivate them?

I think trackers are more intrusive than permissions. Am I right?
[General Questions and Answers] The Penguin:
Yes, only normal permissions get allowed by default, the apps will ask for the rest of them and you can deny them if you want. Also the only way to disable trackers is with aurora appwarden or trackercontrol, but sometimes the apps with disabled trackers could crash.
[General Questions and Answers] Deleted member 1890170:
@MrNice

an app only can track you if it has the related Android permission granted to do so.
[General Questions and Answers] MrNice:
Hummm, for me, these 2 sentences look like an oxymoron.

Could you explain?
[General Questions and Answers] Deleted member 1890170:
My last 2 cents here:

An app doesn't have trackers, it only has granted permissions, but an app may behave as tracker - where it doesn't matter whatever it will track - if it got granted the related permissions.

Have a nice day.
