All,

I can confirm that I am having the same issues with the German HTC stock ROM.

This device has so many bugs that it is hard to believe.

Regards

GZ
[Tilt, TyTN II, MDA Vario III General] isujosh:
Spent some time looking at the problem yesterday - can someone please try out the following;

Set Kaiser/TyTnII so that it stays on all the time (no sleep or power options set), reset the device and let it connect to the AP - leave it 'connected' for approximimately 10 minutes, open IE and see whether you can browse internet - and if you can - for exactly how long before the session hangs?

Do the exact same thing as above (soft-reset) only start IE just after the device connects to the AP and time exactly how long before it hangs.

With both these tests its very important that the machine does not go to sleep or standby etc...

I've dragged out my old Hermes which I am taking in to uni to test with on Monday along with my TyTnII.

Final question, can anyone who has this issue please post;

Device Name (I presume a TyTnII)

Radio Version

OS Build

Access Point Brand/Model

Exact Security used to connect with (WEP/WPA etc...)

FAQs.

1.ROM is based on?

* Roms is Based was AOSP-CAF now its fully rebased to pure CAF with few lineage elements.

2.Supports 4k Video Recording?

* Yes , use SnapCam included in the Project Build.

2 Changelogs?

- Please check my commits on Github or the changelogs section in Settings->About Phone.

3. Does VertexOS work with other GApps, TWRPs, firmwares, SU, kernels, tweaks, Viper4Android, etc?

- Please feel free to try, but I may not give support for issues caused.

4. Deep sleep issues?

- Reboot or clean flash.

5. Mobile network issues?

- Toggle airplane mode to see if it fixes the problem. Please check your APN and Preferred Network Type in Mobile Network Settings. If your APN is missing, please share the APN you want me to add.

6. Why is the security patch in "About phone" outdated?

This ROM tracks CAF, which lags behind AOSP by a bit. However, you shouldn't be worried about this because CAF brings in the latest security commits even when the stated security patch level in "About phone" is outdated. Trust me, I've compared the commits of our CAF tag with the latest AOSP branch commits, and also with the Android Security Bulletin. Please just wait patiently for CAF to update the security patch string. I can easily change it and 'cheat' you guys, but I'm never going to do such a thing. So please be patient and know that your device has the security patches.

7. Facing odd drains and issues with apps (message notifications not showing)?

* Stop restoring them with Titanium Backup

* Stop using hacky tweaks

8. Google Play Services drains?

* Clean flash

* Stop restoring everything with Titanium Backup

9. Losing Magisk root?

* Don't enable the BusyBox option

10.Can I dirty flash over previous builds?

* Yes but you may face some issues.

11.Is it Pre-rooted?

* NO.

12.What about Google Assistant?

* Its in the Project by Default.:D

[Samsung Gear S3] tu3218:
Anyone else experience terrible bluetooth range on their gear s3? It is much worse than my old gear s2. I am connected to a S8 so even with new Bluetooth 5.0, the range is awful. Not sure why. I do have the Gear S3 LTE through verizon but that shouldn't matter.
[Samsung Gear S3] adfree:
Could you please give example?

1 meter or 2 or less?

So we could compare...

:confused:

Question is because..

I have killed 1 SMD part form my SM-R732... during some soldering activities...

So I know why range for BT and WiFi is dramatically lost... :o

In my device. :crying:

[Samsung Gear S3] fred2546:
I actually think it is not that bad. I can walk downstairs in my two story home and keep the connection but occasionally if I stray too far horizontally from where the phone is located upstairs, I will hear the Beep showing I've lost BT. Plaster/lath home.

[HTC U11  Questions & Answers] Anghus:
Has anyone else ran into this?

I am on Verizon, using an unlocked U11, bootloader still locked. I ran the phone on just wifi for a few days before I put my Verizon sim in, and the system had updated from HTC.com over wifi, to version 1.11.617.4 . Up until today, the wifi ran reliably, now it shuts down every 10 minutes. No I am not paying Verizon for the hotspot. I imagine rooting and a custom rom would fix this, but I am about 4 years out of practice, so a simpler solution would be nice.

Thank you all for the help!

If this is in the wrong spot I apologize.

I am trying to get an Android box to work with my Planar standard HID touchscreen monitor (plug and play in Windows, no driver required). I tried simply creating an IDC file and that didn't work.

[Xiaomi Mi Max Themes, Apps, and Mods] ScreaMySkrillEX:
Hey guys...

ScreaMySkrillEX here.

This is an audio mod made for the redmi note 3(kenzo/Kate) which also works on mi max(hydrogen/helium) as both the devices share the same audio codec and streams.

What does my mod do?

It enables dual speaker config on your device and has two variants(htc10/stereo). And there's also a stock version which only tweaks the headphone audio output.

Htc10 version uses both earpiece and loudspeaker for audio output. The output is mono and hence earpiece acts like a mid-range booster and adds more detail to the speaker audio.

Stereo version also uses both speakers for audio output but earpiece behaves as left speaker and loudspeaker behaves as the right speaker.

Instructions.

1) Download the latest zip from the drive folder link below:

https://drive.google.com/folderview?id=0B5ratNhH-7mGU3AtTVFmekE4VG8

2)Reboot to recovery.

3)Flash shox Audio Mod zip.(while flashing the file shows that its made for kenzo/Kate. Don't worry, it will work for your device also xD)

4)Reboot.

5)Feel the shox effect!

Enjoy the music...

If you have any requests or problems, feel free to ask.

I will definitely help you.

And you guys are most welcome for your suggestions.

Read the 2nd post for more info and recommended tips.

Thanks to:

[MENTION=2760454]chdloc[/MENTION] - For his biquads app and support. He has thought me many things. A brilliant dev.

[MENTION=6366997]UltraM8[/MENTION] - For his Ainur Sauron audio mod.

[MENTION=3901724]zhuhang[/MENTION] - For his viper4android app and IRS samples.

[MENTION=7955495]Albertkuba[/MENTION] - For actually informing that this mod works for mi max too. This thread is because of him

[MENTION=4388232]ZeroInfinity[/MENTION] - He is the inspiration for me. His works are really brilliant.
[Xiaomi Mi Max Themes, Apps, and Mods] ScreaMySkrillEX:
This is a guide for creating your own biQuads which replaces the existing ones in the mod.

As you all know, biQuads is a set of 5 IIR filters which can be used to enhance the music and also correct the frequency response of the headphones/earphones which you use.

Continue from here only if you know what sampling rate, bit width, lowpass, highpass, peak filters mean. Otherwise google those terms and learn what they are and what they do :D

So here's how to design your own biQuads and listen the music in your way:

1) Download biQuads flashable zip from the XDA thread here:

https://xdaforums.com/android/software/reference-qualcomm-audio-codec-iir-t3093000

Thank [MENTION=2760454]chdloc[/MENTION] for this great work.

2) Flash the zip in recovery and reboot.

3) You will see an app named biQuads in the apps drawer.

4) Open the app and give it root access.

5)As I told earlier, there are biQuads numbering from 1 to 5

6)After every filter you create for every number, tap design biQuad and wait for 20-30sec. You will be redirected to another window where the app check whether the filter is designed correctly or not with a spectrum graph. After that, increase the biQuad number

7) Do the same step 6 again and again from 1 to 5 until your biQuads is ready.

8)Finally, select review filter where you get a final graph and parameters of different IIR filters.

9)Then select save and give your biQuads a name(make sure there are no spaces included in the name). Click accept and the file gets saved in the internal sdcard with the filename you specified.

10)Open the *.coeffs where * is the name you specified for the biQuads in a text editor.

11) Replace IIR2 with IIR0 wherever found and change INP1 to INP2 wherever found.

12) Finally copy everything from the file and replace the contents in the mixer paths(present in /system/etc) under path name headphones. You will find similar lines there which are my biQuads already implemented.(make sure that you file editor has root access)

13) Replace those lines perfectly and align the lines as they were. Save the file when you are done and reboot.

14) Magic.

No luck: it's me?

Edit: weird, the problem was only accessing from my Mi Max.

Thanks, i'm gonna to try your mod.
[Xiaomi Mi Max Themes, Apps, and Mods] Cooly568:
Is there a way to make the earpiece speaker louder that default? On the Mi Max, mine at least, it's far quieter than the main speaker, meaning it, doesn't seem like it does much.

This also means that in Stereo mode, the left channel is far more underpowered when stereo content is playing, and it's noticeable.
[Xiaomi Mi Max Themes, Apps, and Mods] ScreaMySkrillEX:
Maybe htc10 version is more suitable for this device..

If you have a kernel with sound control, try increasing microphone volume.
[Xiaomi Mi Max Themes, Apps, and Mods] Cooly568:
Was the same with the HTC10 version, and I'm not sure if I have a kernel that can do that, and even if I did, how would I go about doing that?
[Xiaomi Mi Max Themes, Apps, and Mods] Cocoyg:
Discovered a bug with this mod. Installing this would disable mic thus any video you record has no audio. Worse uninstalling this mod would not remove the bug. So I had to reflash ROM.

Tested with Mi Max hydrogen 6.0.1 + Audio Technica ATH-IM50/ATH-M40X/Trinity Delta

For anyone who suffer same bugs, replace mixer_paths_wcd9326.xml and mixer_paths.xml in /system/etc and set permission to 0644

Hi,

Will this work on stock rooted nougat based rom 8.5 ? please revert as i m finding it impossible to install viper on nougat for mi max prime helium
[Xiaomi Mi Max Themes, Apps, and Mods] bluviper:
Viper4Arise is only used to further tweak the settings that this MOD offers.

so i think its just but OK not to install Viper.

also, if you already have a 3rd-party recovery, you can easily flash this.
