Bravia Engine is a little mod that will improve your graphic's and video's qualities.

More info here

The screen patch is a fix for people who have issues with the Tipo (Dual) touch screen.

Some people have the issue that their touch-screen is not functioning correctly, usually they describe their problems as: "My touchscreen is laggy/lagging". This screen patch will re-calibrate your touchscreen and fix the issues.
[Sony Xperia Miro, Tipo (Dual), J, E] Eth4n:
Some tests around with and without bravia engine? I tested it on a GT540 some time ago, there was no difference between images.
[Sony Xperia Miro, Tipo (Dual), J, E] kurotsugi:
Bravia engine only work in sony's device since it need support from the rom made by sony. That's why it doesn't work on another device. I never got any report that it work on another rom like cm neither. Even if it cm in sony. Anyway, this bravia engine port in this thread is incomplete. You'll need a framework file, a xml file, and a lib file for complete working bravia engine. The two lines in build.prop is needed to show bravia option in setting. However,the bravia engine won't work until you have all the rquirement. This is the reason why most people can't spot the differences after using this bravia mod
[Sony Xperia Miro, Tipo (Dual), J, E] ChinchilaO:
Where do we find this lib and xml file?

I suspected that soemthing was missing

I have it...but I can't upload it due to my slow internet connection at this moment. Ill tell you later when I managed upload it
[Sony Xperia Miro, Tipo (Dual), J, E] kurotsugi:
Here is the complete file as I promised. The movie effect only work if you use movie player in my thread about clearbass mod. The photo's differences isn't as clear as you can see in another device with lcd screen but the if you compare the filesize, you'll know that the mod is working
[Sony Xperia Miro, Tipo (Dual), J, E] balboarocky:
Slight difference noticed in tipo ..thanx:)
[Sony Xperia Miro, Tipo (Dual), J, E] cipjanin:
should i install bravia on tipo? and if yes , why? it is worth though?

also can u add some pictures , so we can notice the difference if any?
[Sony Xperia Miro, Tipo (Dual), J, E] Dragoboss:
I will try to make some screenshots of that soon.

Now, Bravia Engine doesn't make a REAL big difference on Tipo, but you will see a bit improvement.

As far as I know it isn't really hard, and neither really risky, so I guess you could just install.

EDIT: updated the steps with Kuro's files.
[Sony Xperia Miro, Tipo (Dual), J, E] smartyyadav:
Should i have to install both blindshooter's and kuro's file?

What instruction to follow to install kuro's files?
[Sony Xperia Miro, Tipo (Dual), J, E] Dragoboss:
I put a stripe through blindshooter's files, the installation steps are for Kuro's variant now.

Just follow those :good:
[Sony Xperia Miro, Tipo (Dual), J, E] smartyyadav:
One more question pls

After modifying build.prop will i have to clean dalvik cache before reboot?
[Sony Xperia Miro, Tipo (Dual), J, E] Dragoboss:
nope, no need to
[Sony Xperia Miro, Tipo (Dual), J, E] littlepai007:
i want to instal bravia engine on Tipo(Single). I made a back-up using TB. I download BE.rar folder from the mentioned link. But i dont know where is /system. Is it the one in internal memory? And also i couldn't fint build.prop file!. Please tell me how to proceed.
[Sony Xperia Miro, Tipo (Dual), J, E] Dragoboss:
Have you got a file-manager that supports root?

Practically it's like this:

./ folder = the main folder,

in this main folder there is folders like "system", which is the system partition, "data" which is your phone data partition, "sdcard" which is internal memory/the 2GB space think where u usually put ur files and sometimes apps, "ext_card" which is the external sdcard you inserted. And many more folders. But you need a root File-Manager to see those folders usually.

The build.prop file is also in the system folder...

I'll add a screenshot of my Root Explorer being in the main folder.
[Sony Xperia Miro, Tipo (Dual), J, E] littlepai007:
Thanks Got it!
[Sony Xperia Miro, Tipo (Dual), J, E] GoOxT:
It Works?

Wysłane z mojego Sony Xperia Tipo.
[Sony Xperia Miro, Tipo (Dual), J, E] Dragoboss:
Works on all phones of this section ;)

Tested 100% for Tipo!
[Sony Xperia Miro, Tipo (Dual), J, E] GoOxT:
BE

I rather it was about whether you can see the difference the original and converted BE. Photos and movies are better in addition to something else? This consumes a lot of battery?
[Sony Xperia Miro, Tipo (Dual), J, E] Dragoboss:
Oh sorry, euhh. Some users have reported to see a difference. Personally I thought I saw a slight bit of a change. But some others have reported that it didn't work on their devices.

I guess you should just try. ;)

It does use a bit more battery as far as I mentioned. But not a huge bit.
[Sony Xperia Miro, Tipo (Dual), J, E] Eth4n:
Make 2 screenshots of the same image with and without BE and post them here
[Sony Xperia Miro, Tipo (Dual), J, E] piku 123:
Dragoboss Are these instruction for kuro's files and what editor should you recommended to edit build.prop sorry for being noob I am a new android user.
[Sony Xperia Miro, Tipo (Dual), J, E] Razhad:
you can use root explorer to edit those file,
[Sony Xperia Miro, Tipo (Dual), J, E] piku 123:
I mean how can i edit build.prop?
[Sony Xperia Miro, Tipo (Dual), J, E] Razhad:
just long-press the build.prop & then choose open with text editor
[Sony Xperia Miro, Tipo (Dual), J, E] Shambumon555:

[Sony Xperia Miro, Tipo (Dual), J, E] macveriz:
Work for my typo ;)
[Sony Xperia Miro, Tipo (Dual), J, E] Ketansa:
Replace the three folders?

It will delete entire original contents of the folders and just keep the BE files. I think you mean, move the files contents of those three folders to the specified folders. yes?

And, should I give the RW-r-r- permissions to all those files?
[Sony Xperia Miro, Tipo (Dual), J, E] Ketansa:
Well, I did this Bravia mod. And all my videos played with continuous breaks and pixelating. images also looked pixelated in some parts.

I deleted the added text to build.prop file. and deleted all the files that I had pasted. then rebooted again. will this restore to what it was before?
[Sony Xperia Miro, Tipo (Dual), J, E] Dragoboss:
It should just merge the folders, that's what happened to me...

Strange, because it doesn't change anything to the video player app, and it SHOULD enhance the images, not make them worse.

Have you rebooted after you done this all, and are you sure you've done it correctly?

Removing the lines from the prop, will remove the option to enable and disable, so will probably disable the whole mod.

About the files, most of them are free too be deleted, altho I believe a few small files replaced exsisting files.

I'm not sure which, as again, these aren't originally my mods, but Blindshooter seems to have gone inactive in this forums, and Kurotsugi should still be here. I hope he reads they and confirms which files overwrite or not. ... :good:
[Sony Xperia Miro, Tipo (Dual), J, E] tasosl:
i did it but no deference until now..video playes well..nevermind thx...
[Sony Xperia Miro, Tipo (Dual), J, E] osa_misuari:

I think its better to Post this here,when its not better,than sorry!!!

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

Once a brief statement for those who are not traveling so long in the Android scene:

ZRAM = ramzswap = Compcache

In order to explain more precisely ZRAM first need other terms are more clearly defined:

Swap can be compared with the swap file on Windows. If the memory (RAM) to complete the PC the data that are being used not actively outsource (eg background applications) so as to re-evacuate RAM free. To this data is written to a hard disk. If required, this data is then read back from there easily. Even the fastest SSD is slower than the RAM. On Android, there is no swap!

In ZRAM unnecessary storage resources are compressed and then moved to a reserved area in the fixed RAM (ZRAM). So a kind of swap in memory.

This Ram is more free because the data then only about 1/4 of the former storage requirements have. However, the CPU has to work in more because they compress the data has (or unpack again when they are needed). The advantage clearly lies in the speed. Since the swap partition in RAM is much faster than this is a swap partition on a hard drive.

In itself a great thing. But Android does not have a swap partition, and therefore brings Android ZRAM under no performance gain as would be the case with a normal PC.

In normal PC would look like this:

Swap = swap file (on disk) -> Slow

ZRAM (swap in RAM) -> Faster than swap

RAM -> Quick

With Android, there is no swap partition, and therefore brings ZRAM also no performance boost.

The only thing that brings ZRAM is "more" RAM. Compressed by the "enlarged" so to speak of the available memory. That's on devices with little RAM (<256MB) also pretty useful. The S2 has 1GB but the rich, and more than. There must not be artificially pushed up to 1.5 GB.

After you activate the ZRAM also has 2 disadvantages. The encoding and decoding using CPU time, which in turn has higher power consumption.

Roughly one can say (For devices with more than 512MB RAM):

Without ZRAM: + CPU Performance | + Battery | RAM

With ZRAM: CPU Performance |-Battery | + RAM

For devices with too little RAM so it makes perfect sense. But who shoots the S2 already be fully complete RAM and then still need more?

Check whether you can ZRAM runs in the terminal with

free or cat / proc / meminfo

I hope it helps to understand zRam!!!!:o

Yeah thanks indeed for the info - so does this mean that we must have zram disabled because of low memory ?
[Galaxy Y GT-S5360 and Duos 6102 Q&A, Help & Troubl] -CALIBAN666-:
no its very good for devices with less ram like 289mb and we have less ram,so its useless for higher ram devices with 800-1000,but that can u read in this guide;)
[Galaxy Y GT-S5360 and Duos 6102 Q&A, Help & Troubl] nikufellow:

[Galaxy Y GT-S5360 and Duos 6102 Q&A, Help & Troubl] -CALIBAN666-:
not really because the system all the time creates virtual ram and distributed, just as if the ram is not needed, because then the virtual ram not needed and the system distributes it then falls to a normal ram, but I think it also comes to the what and how much the device is made for running multiple concurrent tasks, it is recommended.

@CALIBAN666

ramzswap != compcache. both using compressed data on memory. both even from the same person AFAIR. the different is ramzswap using compressed swap and compcache using compressed cache.

kernel 2.6.35 source code from samsung have ramzswap support, but you need user space program to enable it (need little patch to build it for sgy but it's easy).

[Galaxy Y GT-S5360 and Duos 6102 Q&A, Help & Troubl] celisdelafuente:
swapp != zram

With swapper you can have an swap file or you can choose to partition your SD-Card to have an swap partition there. Swap is not used by default in Galaxy Y and swap space is optional not really needed in Android (or Unix/Linux in general).

On the other hand, zram is a whole different beast.

i am little bit confused do i have to disable Zram and enable swap partition or just leave as it is :P

have found a lil more about zram,i hope it helps anyone!!!!:)

zRam(Zero Capacitor Ram)

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

zRam is an experimental(staging)module of the Linux kernel.It was previously called"compcache".zRam increases performance by avoiding paging on disk and instead uses a compressed block device in RAM in which paging takes place until it is necessary to use the swap space on the hard disk drive.Since using RAM is faster than using disks,zRam allows Linux to make more use of RAM when swapping/paging is required,especially on older computers with less RAM installed.

To make it simple,zRam allows to virtually increase the amount of RAM your device has by using the Swap spaces in your device memory.This is mostly profitable for "LOW-END DEVICES" that come with "FEW RAM" (512mb generally).

I have a Galaxy S3 with Googy Kernel, I have installed the stweaks app and it gives me the chance to set the ZRAM at 200 mb with 80-90% swappiness... Is this worth for me? Would I get more free RAM memory? Or would I have better performance playing games?

I am currently on Stock running Jarvis Kernel on my Galaxy Y. The kernel says it supports zRAM, so how can i enable it? :confused:
[Galaxy Y GT-S5360 and Duos 6102 Q&A, Help & Troubl] -CALIBAN666-:

[Galaxy Y GT-S5360 and Duos 6102 Q&A, Help & Troubl] karnal.girish:
can the zram be programed if so how

this is very informative thank you.. i have a doubt... can we redirect the zram to a sd card partitioned space, or it wont help if as it utilizes the same space as before... i am using iberry auxus note 5.5... it has 2gb ram so there is not need of zram for me i guess but still if possible would help to speed it up a little
[Galaxy Y GT-S5360 and Duos 6102 Q&A, Help & Troubl] totiadrenalin:
Is enabling the ZRAM is the correct step to gain performance?!!

If you really like to speed up your android device (iberry auxus note 5.5) that have 2gb of ram, then activating the zram is the first wrong thing you could do!

Anyway to activate zram your kernel need to support it, and except if you are running some custom rom on your device with enabled zram functionality, the Manufacture of your device will never let you do this on it by default!

But even if you do activate the Z-Ram ( aka compcache - Compressed cache) then you will loose some of the CPU's processing power for compressing and decompressing the inactive applications into a separated memory block in the devices Ram memory. Also this lead to less idle state of your device, because the CPU will wake up pretty often trying to compress and decompress the needed data, so this will leed to more battery consuming. And if you like to get some gaming performance you will have to activate the GPU rendering, which will also lead to more battery consuming, and over all you will loose much more than you could get from the Zram!

Anyway for those devices with 512 mb of ram or even less, my advice is to try to setup the OOM minfree parameters (Out of memory killer - The task manager integrated in the Android kernel) values, so less inactive cached apps will occupy the ram, in other words more free ram for the foreground, Visible and secondary Server(Services) applications.

The main disadvantage: the more aggressive the minfree values you set, less multitasking you'l get.

Also you could play around with the sysctl command (system control).

Finale conclusion: If ZRam was necessary for your device's performances, than it would have been pre-activated by default!
