Having problem searching GPS in stock .89. Will sliding xu kernel help improve GPS reception? GPS was snappy when I was using zperience Rom with sliding xu kernel so I'm not sure if it were blessing of that Rom or the kernel.

Secondly, when I was using zperience there was a cpu control option under developer option where I could select governor but there is no such option in stock .89. How to get it.

Tested on xperia u JB mod V3 Dew.

It solves the problem root works fine but I notice slowness in the reboot.

Unfortunately alters the proper functioning of illuminator bar is not doing more work, the LED color when viewing images or works not fixed but flashing. Excellent choice of recowery fpx, excellent fluidity, but no savings of RAM. I continue to test ...
[Sony Xperia P, U, Sola, Go] wisnuhadi23:

[Sony Xperia P, U, Sola, Go] fareed_xtreme:
+1.

Edit

Managed a workaround.

1. Make sure none of the apps use the LED Notification Light (The small light beside the front camera. Examples of Softwares are Whatsapp etc)

2. Install Illumination Receiver by Rundgong.

3. Install Illumination Bar by Rundgong and control notifications from there instead.

Tested and its fine. Album Walkman and all app notifications will have proper LED Support. I hope OP can fix it when he has time but it is the least of our worries, trust me.

JB for XU has major issues. So would have to be patient My apologies. I wrote that in a hurry and seems like I gave out some false information. Thus striked that statement. Thanks to Satya to point it out.

[Sony Xperia P, U, Sola, Go] fareed_xtreme:
Apologies. I wrote that in a hurry. Will edit it. Front cam and LED means nothing much to be honest to me. But battery drain... That is something that needs work amd I have myself been breaking my head to know what is causing this drain. I am trying this Sliding XU kernel and seems a bit better but might as well be the placebo effect. Need to verify with numbers.
[Sony Xperia P, U, Sola, Go] wisnuhadi23:
If you have ever used betterbatterystats you would likely understand why.

Under process, we have too many kworker processes going on and using too much cpu, that is why when you see battery usage you will see androidos next to screen.

I am not so sure about this, deepunkown must know much better about kworker since it is something related to kernel.

This was also the same issue we had on ICS.
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Again !! I thought that was gone :(

Will take a look at it, that will really cause some battery drain :-/
[Sony Xperia P, U, Sola, Go] wisnuhadi23:
Unfortunately :(

By the way, I noticed that it did not happen only on your kernel. Last time when I was on ICS I tried CM based ROMs, clean install without any apps, with FXP kernel, I still had those crazy kworkers. Even on JB, while I was on devswift's kernel those annoying kworkers do not want to go away, I guess they found their home, hahaha
[Sony Xperia P, U, Sola, Go] OmarBizreh:
Hmmm.... I suppose it's obvious now. Will update tonight hopefully.
[Sony Xperia P, U, Sola, Go] wisnuhadi23:
What is actually the reason behind it ? I have been searching all over google yet I could not find any explanation for that and I could not find possible solution.

Anyway, take your time, don't let these kernel developments ruin your study.

I am also a student so I can understand you, just focus on your finals first.

Cheers.

[Sony Xperia P, U, Sola, Go] ashisharia:
Like this kernel a lot, especially no overclock and change in frequencies value.. can you have cwm 5 in next version? It's better than cwm 6 for xpu as it's more stable and can mount usb mount
[Sony Xperia P, U, Sola, Go] satya-1998:
Umm, DeepUnknown. I had this suggestion. Could you add new frequency steppings below 1000 MHz to the JB Version? You know like 300 MHz, 500 or 700. Not 100 MHz because it actually takes more battery than 200. Above 200 and below 800 preferably

[Sony Xperia P, U, Sola, Go] fareed_xtreme:
V-4.0 is decent with battery consumption in JB. If you control your Wifi then you can easily pass a day with this. (I use wifi by timer app to control.the Wifi from being on 24x7) Have noticed a few kworkers but still this kernel manages to give a days worth of juice.

Using Interactive and Noop scaling between 200 - 1000MHz on both screenshots. The one with more battery was a test on using GSM only.

Does this allow for some additional insight into the Sony Illumination bar API on an XPERIA ST25i.

Sony Illumination bar API

Sony states:

The Illumination bar API allows developers to control the LED light illumination bar at the bottom of a number of Xperia™ smartphones (see the list of support phones below). Some of the options that can be set are the LED colour, whether or not the LED pulses and time between pulses, and various pre-defined fading patterns

You could also use the illumination bar app from Google play that works on ICS

Has anyone tried Sliding XU v3.5(ICS) on XPERIA U 6.1.1.B.1.100 ROM?

One considers it may be prudent to run XPERIA U 6.1.1.B.1.100 ROM with root access for a few days(a week) without Sliding XU v3.5 and then install the custom kernel later

This would give a better understanding of the ROM without and then with Sliding XU v3.5 as a control.

I don't have an XPERIA ST25i, but have upgraded another persons XPERIA ST25i and would like to know any benefits of the new 6.1.1.B.1.100 ROM and then how that translates into having Sliding XU v3.5 installed.

I normally only get a 2hour window in which to install and test any changes on said persons phone.

So hedging myself against any issues and also leveraging any benefits (i.e your battery will last longer, known bug x is resolved and etc) is a good reason to initiate an upgrade

Update Center

With this custom kernel, the Sony "Update Center" keeps telling that there is the update to 6.1.1.B.1.100 available, although this version is already installed. The reason appears to be the detected custom kernel indicating a lower version. One can clear the message with "Clear data" under "Settings/Apps/All/Update Center", however, the message will come back and it should be a minor change in the kernel to eliminate the message at all.
