I think that HD Voice is a VoLTE (4G) feature so our S2 can not support that, as his hardware can't do it.
[Galaxy S II Q&A, Help & Troubleshooting] Weib67:
I see. Maybe you think that flashing a custom PIT implies a modified preload partition, which would indeed brake stock rom compatibility. But as long as you keep this preload partition, you are safe to flash whatever PIT file you want. Hence different PIT versions available to suit your needs. :)

Could you please share the tutorial used to mount /sdcard0 ? There are several around here, but one that has sucessfully been tested on i9100 is always good to know, just in case.

Actually, according to Wikipedia, it does: en.wikipedia .org /wiki/List_of_smartphones_with_HD_Voice_support (can't post full link, but you get the idea).

Don't know how accurate it is though.

[Galaxy S II Q&A, Help & Troubleshooting] jerjakob:
If you mean after using and switching between different apps, it becomes slow and you get force closes and crashes, this is because of low RAM, which 5.0 manages pretty badly and is a widely known problem, especially on low RAM devices like the SGS2.

[Galaxy S II Q&A, Help & Troubleshooting] jerjakob:
No, the PIT will only give you more space for apps on the flash partitions, since newer versions of android need more space, it's very good, if not mandatory, to do it anyway. It will not give you more RAM, that's a limitation of the hardware.

[Galaxy S II Q&A, Help & Troubleshooting] LeBourrin:
Thanks for the link! I was wrong :silly: and it appears that Galaxy S2 support HD Voice. I confused with the new VoLTE implementation named Full-HD Voice that use better sampling.

EDIT : S2 already have HD Voice because we can enable it in a hidden menu:

Found that in other xda thread and I can get the menu in my Omni4.4 but I can't activate it because my carrier don't support it.

Service menu *#*#197328640#*#*, "[7] WB AMR STATUS", "WB AMR SETTING"

"WB AMR" is Adaptive Multi-Rate Wideband = HD Voice
[Galaxy S II Q&A, Help & Troubleshooting] disorganizer:
Im not in the PC at the Moment so i describe the Methode i used roughly cause i cant find the original guide:

No warranty! Be aware this can break your phone ;)

1) rename /system/bin/sdcard to /system/bin/sdcard_backup

2) copy sdcard script ( inside attached ZIP) to /system/bin/sdcard

3) change permissions oft /system/bin/sdcard to 755 ( rx for all, w for owner )

Boot

The ext SD shoukd be mounted in /sdcard and the infernal not mounted at all after that thread

For the devs:

Maybe it would be a really nice Option to have this implemented in the os ( to be able to choose the system mounts for the internal and external sd cards) without doing dirty tricks

I still wonder why android doesnt use fstab mounts though. That would be the easiest mounting possibility and could even survive updates.

Btw as im at it:.

After a system update i suppose this needs to be repeated ;)

Really thanks for the first awesome "all working" rom in years!

Hi! I'm posting only to say thanks to Lysergic, in years this is the first totally stable and "all working" rom that i tried, even GPS is locking as fast as on stock ROM! The battery life is amazing (Apolo 8 Beta 6 Kernel + Xposed Lollipop + Amplify and massive tweaks to Google Play Services), the only problem i found is that the light sensor is not working, automatic brightness keep bright at 100%, but i dont want to touch this rom anymore haha (Build 03.03) because it's giving 3hs of screen time, with 3G on all time, bluetooth playing, and 12-14Hs of total use time!

Well if anyone wants to use screen pinning in this ROM you should know that you won't be able to get out of the pinned screen as s2 does not have a overview or recent apps onscreen button..

You can use this following command at the end of the build.prop to enable onscreen nav bar

"qemu.hw.mainkeys=0"

Just be sure to make a backup of the existing build.prop before making changes.

Bluetooth A2DP issue: sound stutters constantly

Hi all,

Does anyone have A2DP streaming working with CM12 / Lollipop? According to some googling I did, there seem to be a lot of problems with this, not only on CM12 / I9100.

I'm running CM12 (March 6 build) and find that when connecting via Bluetooth to an A2DP device, the sound is constantly stuttering. As if there is a processor throttle issue or something like that.

The problem is only there when using Bluetooth, internal speaker and headphones are working fine.

Sometimes, after connecting to the Bluetooth device, sound comes out of the phone speaker instead of through the Bluetooth device. In that case, sound is playing without any stutter.

AVRCP (Skipping tracks, play/pause button, track info) is working OK, it's just the sound that is constantly stuttering.

Sound is never OK, the stutter is constantly there.

I have tested with:

* Pioneer DEH-4700BT Car stereo

* OVC3860 based bluetooth speaker

I have tried (found in threads on several other Lollipop phones):

* Disable WIFI

* Set WIFI to 5GHz only

* Enable different CPU governors (e.g. force 1200MHz continuously)

* Remove the Bluetooth connection from the phone and re-connect it

* "Use NuPlayer instead of AwesomePlayer" from developer options

I have also tried a different ROM (Hazy ROM, also found here on XDA), which gave me the same problems.

Before, I was running SlimKAT and back then Bluetooth streaming was working perfectly fine.

Anyone experiencing the same issue, or anyone who's got this working without any problems?

If you're coming from original samsung firmware, you need surelly the cm12 rom, gapps etc., but before you need the right recovery to flash them.

I quickly usually do that:

1) Flash from present recovery this one: PhilZ-cwm6-XWMS3-FOP-5.15.9-signed.zip then reboot to system and back in new recovery.

2) Flash one more recovery to be able to install cm12 (directly from sammy rom is not possible). I use: philz_touch_6.48.4-i9100.zip or CWM-KitkatCompatible-i9100.zip

3) Reboot into second recovery.

4) All wipes needed, format system and flash rom, gapps.....
