+1, lens blur is reported working on the moto g 2013 and it does not have the gyroscope
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] doctorace92:
Lens blur does not work on my friend's Xperia U....which does not have a gyroscope as well. I think recent updates made this feature dependent on gyroscope too like other features. It no longer works on phone without gyroscopes.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] HybrisZero:
just checked on the playstore

photosphere and panorama require gyro and 1GB RAM

lens blur requires 1GB RAM
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] doctorace92:
Thanks...so that's why after the updates, it will work on moto g but not work on xperia u/sola or xperia 2011.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] BealeStBluesBoy:
If you set in build.prop ro.config.low_ram=false Lens Blur become available

Did u flash the right boot.img file?

Perform a clean install (wipe data and cache, format system, cache, data, wipe dalvik)?

If yes, try wipe dalvik and restart and see if works.

Hello!!

I instaled the latest build on my coconut but i thik wifi suspension is not working because in 15 hours of battery consuption i have 10 hours of wifi usage. This means that even with the sceen off for a long period of time the wifi mode does not suspend as it should and only reenalble when the scren is on.

Is this normal???

I flashed the rom properly, and so on, and so on.

Thanks in advance

Hi Mike & guys!! :D

I'm using new build 06092014 for coconut.

Is there a way to fix mp3 cut issue in coconut??

hi,

have done a new build. for now i don't have problems, the LED changes seems to work backlight not turn on on incoming messages.

camera pic and videos work. if the wifi patch works i cant say for the moment.

mp3 fix doesn't work. in some files there are more cuts than other, but i see no patterns. all my mp3 are encoded with lame, mostly in VBR.

and a little thing that annoying me while using. If i try to unlock the device often there is no reaction. if i press the poweroff button and the device go to sleep again and i try to unlock it again it reacts really fast. this behaviour i have for some last relaseses and own builds now. maybe it depends on link2sd? Did someone has similar experiences?

Hi. I was on latest nightly 20140906 trying to tether my mini pro to my tablet then I got a reboot. It doesn't turn back on anymore, freezes on LX logo. Already tried wipe cache & dalvik. Previously(still on 20140906) wifi tether was working although I have to use no password for it. It seems like I have to start over :(

Could mike/someone identify the problem? Attached is last_kmsg. Thanks a lot! :fingers-crossed:

Kernel IO sheduler

@mikeioannina

PLZ dont set ROW io sheduler as default sheduler on ANZU, this is now the 3rd time this year i lost all data on SD when using ROW io sheduler. Never happened on any other sheduler only on ROW this is happening.

Now SDcard is again corrupted and all data lost!!!

ROW is not safe to use on ANZU.

might be also unsafe on other devices.

Happens on my Samsung Device too with different type of SD and ROW
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] bejunk:
Which I/O scheduler you personally recommend?? Btw my sd got corrupted too some time ago, by unknown reason... Maybe due to this. But i can just guess...
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] taurelio:
In case i was not clear that option is enbled on my coconut. The problem is that it seams that is not working properly...
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Mardon:
Every other io sheduler which is available in lx kernel only ROW results in corrupted SD.

Forgot to change it this time and after ca. 20 reboots SD corrupted with ROW :(

Switched to sio now and repartitioned sdcard with aparted.

Personally i would prefer ZEN but its not included in lx Kernel.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] BealeStBluesBoy:
That issue is very strange, I've been using ROW since always with LX and no SD problem happened, maybe there's a hw problem

------------

I see you have two phones with the same problem, woah, maybe you have a really bad luck
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Mardon:
Its no HW problem it also happens on other devices with different SD cards when ROW is used.

ROW = read over write

means read comes first

so if you dont wait long enough after SD write and make a reboot the reboot might interrupt the write process and this leads to corrupted sd.

ROW is only meant to be used on internal device storage not for SD!

And some of the changes we are using is apply sheduler to all storage devices this is also used on my other devices.

Thats the explanation.

Options we have:

1. completely remove ROW

2. revert apply sheduler to all storage types

3. different io sheduler settings for internal and SD storage and blacklist ROW for SD storage

its up to @mikeioannina now to decide which option to choose
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] BealeStBluesBoy:
Do you have a second partition?
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] mikeioannina:
I've been using ROW since forever on all my devices, doing constant tests & reboots every day and I never had a single corrupted SD issue...
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Mardon:
Happens when you have much apps with sync installed and linked them to sd.

ROW also wasnt meant to be used for SD its only meant to be used for internal storage.

One of the reasons why nexus devices doesnt have an SD ;)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] mikeioannina:
I use link2sd with a ton of apps too.

Where did you read that ROW isn't meant to be used for SD? How exactly is this proved? Looking at the documentation I didn't find anything saying that.

BTW I don't understand your nexus reference... what does ROW have to do with nexus devices not having SD cards? Nexus don't have SD for totally different reasons.

This whole conversation reminds me of the pointless conversation in http://review.cyanogenmod.org/65599

Until someone has actual proof that ROW is broken or that a different IO scheduler is better, I'll stick with it. Almost all qcoms use it
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] skaveelicious:
Been using ROW ever since it was set to the default and I have not yet had any fs corruption on my Anzu. Considering that you build from source you can always change the values for your own builds. :good:
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Mardon:
Sure i can build from source but thats not the point.

The point is only ROW leads to sdcard corruption on much devices (all with good brands & fast class 10+ sdcards), never happened with other shedulers.

Setting Row to default is not safe in my eyes.

@mikeioannina

Nexus was reference where row is set default.

Internal storage data bus 8bit

SD card data bus 4bit

Maybe the data loss will be also fixable with a row finetuning, but im out of using row for testing parameters and risk a data loss again.

Maybe [MENTION=3877378]psyke83[/MENTION] can explain the disadvantages of row a bit better.

A few days ago on build 718, my class10 16gb micro sd got corrupted on ROW. At first i didn't know the cause. My pics started to turn completely yellow and then bam, sd card is corrupted. Also, the card was less than a year old. What i/o scheduler to use other than row?:eek:
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] TechExhibeo:
I also didn't faced any SD card corruption

:fingers crossed:

After first boot i change the governors and io to smartassv2 and sio :)

I am using Kingston 16 GB class 4 SD

SD corruption thing happened to my friend last year.

He was using 16GB ultra sd card of SanDisk class 10
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] amishxda:
This statement seems wrong to me. Since android is based on Linux and in Linux there will always be SYNC command for all MOUNTED partitions before reboot (i.e before unmount), it should not cause issue in android as well.(unless android does it in some other way)

Btw, I am using ROW ever since it was default (I did not know what it was though) and have not had SD card problem yet.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] vikusz:
I've had 2 broken SD cards in the last 6 months using LX CM11 on my iyokan. Both were 32 GB, class 10, different vendors (Kingston and Transcend). I haven't changed I/O scheduler, it has always been on default - ROW. I don't know whether the SD corruption is connected to the scheduler, just thought I'll share my experiences since there is a discussion about it.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] amishxda:
Broken has 2 meanings.

Broken as in completely unusable. (can not be ROM fault - unless very bad setting cause too frequent writes on SD card - causing EOL)

Broken as in file system corruption (can be ROM fault). This will cause data loss but card can be re-used by formatting it.

I am using gravity box to solve it with xposed in dalvik mode.

But if you want to run in art mode,the xposed has gone.

I have switched to nexus 5 now, but two months ago on hallon and lx i had my sd card corrupted... I can't use it anymore on any device, it's unreadable.

The sd card was the one sold with my device, so it was almost 3 years old.

I taught it was a failure of the SD card and not caused by lx, but after reading these posts I think that can be some problems with the rom.

I don't remember if I was using link2sd or mounts2sd when the failure happened

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Grof87:
I had issues with the sd card on the latest build also (I've checked the card for errors using PC software and the card is absolutely fine). Sometimes the files copied to the sd card where unreadable, I couldn't partition it using CWM (it says that everything is done but the card isn't formated or partitioned). Also I'm on cm10 now, and there are absolutely no problems (formating, partitioning and everything else).

EDIT: I didn't change any of the settings (I had problems with Viber and was testing to see what was wrong so i kept everything stock).

I had 2 corrupted SD cards in the past 2 weeks after installing build 20140814! now my phone dosen't recognize any sd card, even after flashing ICS stock firmware via flashtool.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Grof87:
I don't have a card reader, just connect the phone in mass storage mode (if using linux read the guide I mentioned).

EDIT: forgot to mention I did all the formating and partitioning on CM10, since I was having issues with CM11 (Viber boot loop).

Well, everything was fine on the build before this one and CM10 that I'm using currently. Like I said my issues using the last build were relatively minor, sometimes the file would copy without problems and sometimes it was defective - it didn't want to open, although no errors were reported during copying, and also I was unable to partition the card using CWM. I've also noticed it takes quit more time to copy files to sd using latest build than CM10 (example: 150 MB file needs 30~60 secs on CM10, but it takes ~3 minutes in latest CM11, and I can't remember if it was different in the previous build). At least in my case the card doesn't seem to be defective.

[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] vikusz:
I had the exact same problem with my Transcend 32GB class 10 card! The card got into a "frozen" state where writing/deleting/formatting had absolutely no effect. Also none of the low level format tools worked. All this after a few month of usage with LX CM11 (several builds).
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] doctorace92:
I do not have any such issues after several non months of usage. I have found a pattern in SD card corruption. Most victims of SD card corruption are users of cheap Transcend SD cards or similar cheap cards. If you Google it up you will find sdcard corruption is a perennial problem of these cards.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] vikusz:
