Hide notification\status bar

Question.

I haven't used any CM since I used Moto Atrix. And there was a beautiful option to hide\show a notification (or status. I have no idea how it called) bar (upper bar with clock, signal bar, etc.) by pressing HOME button. Is there any chances to bring that option back? It was so cool!

And I found CM9 camera app as a piece of cr**. Only "touch to focus" ? Really ? I would lovely use a stock one. Same as gallery app actually.

Only my thoughts. Not more not less.
[Sony Xperia S, Acro S, Ion] Phantasm4489:

I want to install this rom. Is this rom compartible with the Advanced ICS Stock kernel with Custom recovery build in ?

If so, will the kernel replaced by the build in kernel from CM 09 ?
[Sony Xperia S, Acro S, Ion] SilentEYE:
as far as I saw the rom will install its own kernel.

but I am sure u can install it on your current system without problems.

It looks like there are some problems with compositing, sometimes the screen will not update when it's actually needed. Trying to figure out what causes it...

Edit: found it on the bug tracker, issue 639. Added logcat, will look at kernel sources tomorrow.

Edit 2: Looks like the framebuffer cannot into RGB565, the same thing as on Samsungs.

debug.fb.rgb565=0 in build.prop seems to solve most of the bugs, but I might have seen similar errors pop up a few times. I'll double check that, but for now the build.prop override helps.

I really like this Rom and want to use it. Unfortunately I have GSM reception issues. I will have signal and randomly after a couple hours of use ibno longer can find cell service. At this point its nearly impossible to bring it back.

Anyone else experience this and is there a fix?
[Sony Xperia S, Acro S, Ion] Abandoned-Trolley:
Ok problem with screen not updating is back seems this fix doesn't work sadly :(
[Sony Xperia S, Acro S, Ion] K900:
It does work, but not for all cases it seems. It's something in the kernel, which I'm pretty sure is related to CAF buffer alignment commits not working as planned.
[Sony Xperia S, Acro S, Ion] SGR[robin92]:
I had that with 131, with 132 no problem:D
[Sony Xperia S, Acro S, Ion] ej_424:

Same for me on 132 it can't find my network so phone connect on other operators network (roaming fees as I live near a border), didn't noticed any problem when on 131 but only kept it one day...

Is it worth submiting a bugtracker ticket ? Not sure how does it works...
[Sony Xperia S, Acro S, Ion] elvirag:
Omg... just Google stuff before you actually do them... tech support elvirag to the rescue... Google Mac address. Now you need to find out all macs on your devices... update me in private...

I googled it before i ask...

i was able to add mac address of other devices & they worked just fine, but adding Xperia S CM9.0 mac address didn't work!

cant find any AP in CM9.0...

I asked because i couldn't fine the solution.

The Problem is:

when I enabled mac filter with out adding mac address, other devices found the AP(can not connect) but CM9 didn't show any thing!

adding mac address didn't help it either.

it seems WiFi is not actually ON.

first of all, great ROM, thanx for that.

All is working fine and at great speed. I would just like to be able to move apps to the SDcard, will the next version support that?
[Sony Xperia S, Acro S, Ion] Otkudja:
First of all, thanks to the devs for the great work.

I have installed yesterday CM9 with 639 patch. At first it did not work, I had to try almost 15 times before it worked. It did restart it self in cwm when I have tried to mount system or install cm9.

It is very fast but I have noticed that gsm network randomly disappears, and after reboot it works again. Today I have seen that it went gone yesterday night and it came back when I have turned WLAN.

I have tried it couple of time and it seems I can turn network on and of with WLAN.

I have read earlier posts and did not found similar bug.

[Sony Xperia S, Acro S, Ion] Otkudja:
If we only need to keep WLAN whole time on to have network reception then it is ok, bad is when network disappeaers without knowing. I like cm and how light and fast it is.

CM10 is still to buggy but soon it will be ironed to, FXP devs are doing great job.
[Sony Xperia S, Acro S, Ion] 3Shirts:
I've had that issue with every ICS rom I've used, both stock and custom and with many many different kernels. Strangely I've not noticed it yet on CM9 but I'm sure it's on the way!
[Sony Xperia S, Acro S, Ion] realfelix:
the only 2 issues i found in this ROM is, that it sometimes hangs and the lockscreen disappears when turning the phone on and in the browser some websites do not load as they should.

I'ts possible flash the stock basebands into cm9 rom? Maybe this solve the problem?

HDMI/Bravia/xLoud not work

SMS over 160 characters does not send
[Sony Xperia S, Acro S, Ion] sixdaysandy:
Bravia & xLoud are Sony modifications, it's not that they don't work it's that they are not part of CM9, and as pure CM goes they never will be.

The SMS issue is a known bug and is on the bug tracker; HDMI has been disabled, reading through the thread it may be introduced in a later build if feasible.
[Sony Xperia S, Acro S, Ion] realfelix:
bravia is a real battery killer so i dont mind.

xloud.. the sound is loud enough imo

sms.. doesnt matter to me as im mostly using whatsapp.

oh and if you really want bravia engine on this ROM, ask a dev on the forums if he can make a flashable zip. I've seen ports from Xperia Arc to Xperia X10 when i used the x10 in 2010.

It's confirmed that supported devices will get stable tonight but the Xperias are not officially supported CM devices. Releases for unofficial devices are purely down the relevant teams, in this case FXP.

FXP can you make a normal flashable zip?
[Sony Xperia S, Acro S, Ion] avindal:
It would be infinitely more helpful if you provided what error bugs / error messages you got when you tried installing it, and exactly what steps you followed. Like a bug report..?

if it complains about "asset failed" or something, then unzip the package (on your computer), go to the folder

META-INF\com\google\android

and edit the file updater-script (with notepad++ for example).

Remove the first row (might look like 3 rows) so that the file starts with this:

package_extract_file("system/bin/backuptool.sh", "/tmp/backuptool.sh");

Then save the file, go back up and zip the package again (the unzipped contents!) and transfer to your phone, then flash the kernel with Fastboot and then flash the zip and the ics gapps zip, then reboot...

Like said before... Flashing this update with the boot.img in the zip doesn't work. But Flashing bin4ry's recovery, then flashing the update and then flash the boot.img from this update works.

But Wi-Fi doesn't work, BT doesn't work, so there is some work needed, but aside from that it works great and smooth!

I would love to try this but I haven't quite figured out how to flash this. I got Doom Recovery, I'm getting the assertion error someone else posted before.

Can anyone give me a more detailed instruction on how to flash it?

It would also be useful for other users if the first/second post statet how to flash this under Dooms Recovery
[Sony Xperia S, Acro S, Ion] kazuni:
you can do so by :

1) having a rooted system

2) modify your /system/bulid.prop

make sure in that file, the aforementioned lines are saying "nozomi".
[Sony Xperia S, Acro S, Ion] onemandivision:
thanks!

for the others who are also trying this: after this you also need to flash the boot.img from the zip file with fastboot (at least I had to in order for it to boot)

by the way: you guys are awesome. this firmware so so freaking smooth! if there was a way i could enable mobile data, i'll definately stick with it, even without wifi
[Sony Xperia S, Acro S, Ion] kazuni:
The only 3 reason I can think of is version control (like, if a critical / major flaw/bug is found, it won't be spread wide), discrepancy of original content (i.e. an implanted malware/virus), and counting the amount of downloads.

Cause, the project's nature is to allow as much user as possible to experience the Xperia S with FXP's CM9 build... wouldn't a widespread / be better?

and for the discrepancy issue, the downloader had already taken the risk of retrieving it from a third party mirror anyways.
[Sony Xperia S, Acro S, Ion] 3Shirts:
Same, I edited the build.prop so it installed ok but it just reboots after the doomkernel logo
[Sony Xperia S, Acro S, Ion] kazuni:
Use bootloader mode to flash the boot.img inside the zip file.
[Sony Xperia S, Acro S, Ion] 3Shirts:
Sweet. Got it installed and working. It looks great and seems really smooth though there isn't much to test with the lack of Wifi or GSM. Nice to just have a CM rom running on my XS though, it's like an old friend after the Nexus S I had before that was running it for a good few months.
