Battery lovers enable mpdecision it's off by default. Set maximum frequency to 700 mhz and Governor on demand. 16 to 20 hours idle battery life with movement. 20 to 24 hours if kept idle. 5 to 7 hours sot. What more can anyone expect.

---------- Post added at 04:58 PM ---------- Previous post was at 04:41 PM ----------

I was talking about this see attachment it's taking whole screen. Feels wrong should show one notification in screen.
[Samsung Galaxy Grand Quattro] Tsun_Pooka:
I've still no idea what's causing the full-screen notification, so I can't help here. But at least can you tell us how to enable mpdecision, and what's the best program to control the processor and governor?
[Samsung Galaxy Grand Quattro] Natus Chaos:
Tip

Use Kernel Audiutor to control governor and others things to save battery, but don't change the governor if you not have aplied the pacht to Kernel, phone will reboot, and about mpdecision do this, go to developer settings and enable terminal local app, you should see a new app in the drawer, open it and type:

su (to allow superuser permission on pop up)

Later type:

start mpdecision

And it should be running, if you are using Kernel Auditor a new menu CPU hotplug will appear where you can disable or enable manually, if you are not using Kernel Auditor you have to do the terminal command again when you reboot the phone.
[Samsung Galaxy Grand Quattro] z1_nile:
Use arubadel app it's nice simple. Mpdecision is under Misc stuff menu.

Bonus you can change selinux too probably someone will need that for v4a. Changing dpi drops the curtain /quick settings a little upwards. Like just a centimeter or 20 pixels lol.

And what's the problem of these guys if live display ambient display and auto brightness is on by default we only have to disable once per clean install.
[Samsung Galaxy Grand Quattro] SonOfSparda:
There is an bug in cm. If you disable LiveDisplay, it won't fully restore the default colors.

SOT is good but idle drain is not.

In stock rom, idle drain is totally 0% in more than 8hrs

People flash custom ROM's to get best battery life n performance but in this case, it was reversed :(

Hope they all get fixed soon.

[Samsung Galaxy Grand Quattro] Natus Chaos:
Thank you so much for keeping on this, anyways I want to share something weird.

I managed to fix the Youtube and video lag without the frequences pacht by using L Speed Beta, it's something relacioned to mpdecision and the way I keep it on, I used the terminal to start mpdecision and opened L speed to check if it was working, with the toogle triggered cpu tab wish means yes, then I rebooted and L Speed aplied the settings so I found videos are working good without overheathing the phone, I so happy, I think this could save more battery but the problems start now, I shared this tip to a guy but he did not have the same sucess, probaly the fix could be in my buid.prop or init.d folder because I tweaked all the phone trying to have good battery and speed, can someone try and report?
[Samsung Galaxy Grand Quattro] Ash52:
I will try
[Samsung Galaxy Grand Quattro] MM.626:
my youtube have never lag before, even on 480p maybe keep your phone cool?

Reboot recovery, open file manager, delete the app from data/app/"whatever the app name is"

It will uninstall ac3 player then reboot

Install mx player from play store. Download mx player codecs from xda (optional)

Enjoy.

[Samsung Galaxy Grand Quattro] Dan_Jacques:
I saw in config file the F2FS is enabled. Is this great FS fully supported? Can I format my /data into F2FS (rev2) through TWRP 3.0.2?

---------- Post added at 08:40 PM ---------- Previous post was at 07:48 PM ----------

Whatsapp Messenger says device it's compatible.

WTF DUDE

Suggestion: could you add lazyplug hotplug?
[Samsung Galaxy Grand Quattro] singh.adi.niranjan:
Can anybody please help me...

I have done everything right...

And installation was succesfull

But i soon noticed that the rom has only one problem...

"There is no Signal" can anybody fix this.. Please

Beacause without this i cant do anything..

Network is the most important thing u know
[Samsung Galaxy Grand Quattro] tejus:
U did clean install (eg wiping system , data etc)

Nd which ur twrp version is latest 3.0.3?
[Samsung Galaxy Grand Quattro] tejus:
Yeah added f2fs but now whole rom needs to built again and new twrp will also needed as m busy in exams so cant build rom with f2fs support for now
[Samsung Galaxy Grand Quattro] Dan_Jacques:
Fine. Give attention for your exams. We wait, relax.

Please see the Device ID. I think something is wrong. I can't install Whatsapp though Google Play, only through apk file.

Well, the requests:

- F2FS

- SDCardFS (improve A LOT the read/write operations without need format anything - Infos: https://www.xda-developers.com/divi...les-fuse-replacement-will-reduce-io-overhead/ )

- Device ID fix (Whatsapp doesn't install from Google Play)

- Hotplug (lazyplug/intelliplug/MSM Hotplug/Zen Hotplug, all great options)

Please pay attention to SDCardFS. It speed up a lot the filesystem operations (both internal and external). It improved my Redmi 2 performance HUGE, and it's useful to MM in low storage phones like ours, speeding up operations and improving the adoptable storage performance.
[Samsung Galaxy Grand Quattro] Natus Chaos:
Maybe

Perhaps a possible fix for the ID problem can be solved by taking the ID on default stock build.prop and putting in the LOS build.prop? And I think the mpdecision must be active by default on kernel with the wake up of cores on touch of screen to 700mhz instead of 1080mhz which

drain battery so fast, cause all cores jump to this high frequency at the same time on every touch, we don't need the cores jumping too high for example while typing on a chat on WhatsApp or Telegram or everywhere. :fingers-crossed:

I flashed with philz cwm and it worked. No prob at all.

---------- Post added at 05:39 PM ---------- Previous post was at 05:32 PM ----------

Normally, i use a long procedure before flashing any new rom.

Through cwm..

Wipe data / factory reset

Also clean to install new rom

Wipe cache

Wipe dalvik cache

Then i restore stock rom

Then factory reset via settings

Then all steps again through cwm

Then new rom

It may be a long (and may be unnecessary) procedure. But after following this i do not get any bootloops etc problems.

So far, i have tried 7 different roms, all flashed through cwm, and faced no problem whatsoever, except those which are there in the rom itself.
[Samsung Galaxy Grand Quattro] Natus Chaos:
Any news about the new update or Los 14.1? I'm in a Telegram group and the people there ask about it everyday, I know is not good asking for etas but this waiting is making me kinda sick, if we have a no or date will be better.

[Samsung Galaxy Grand Quattro] raymonardo:
Thank you for the great software

i had been using philz touch for years, and switched to twrp explicitly for this.

stability is quite good.

some weird intermittent behavior of unable to control dimness of the display from time to time.

added Gapps arm 6.0 pico 20170325

first power up is all fine.

setup wifi, login to google account, downloaded some apps all went fine.

until i do a reboot or power off.

the next power up,

the phone always stuck at "preparing google play services" even after a few retries.

wiping dalvik and cache doesnt help.

i had to reinstall the zip and clean the cache to able to power up again. which mean all the apps gone and login need to be done again.

anyone know how to fix this situation?

cant find anything relevant online for now.
[Samsung Galaxy Grand Quattro] Natus Chaos:
You need to wait more, it's normal because the rom use low cpu clock, keep touching the screen and it will be done. :fingers-crossed:

There are also bugs in Brightness adjustment, Haptic Feedback and the already known CAM Video Record and Screen Record.

I'm running this "ROM" in GT-I8552B... And probably it's one of the greatest Custom Roms out there, needs debugging and some another performance improvements and adaptation for my device.

[Samsung Galaxy Grand Quattro] JulianoXDA:
If you really want to participate for the development of this device you could just build AOSPA(Paranoid Android) Marshmallow for us. The device tree is in github.com/I8552-CM. The reason it's performance is pretty poor because it is using other device's GPU driver i just forgot what device it is but it's a samsung device maybe S3. Find a good GPU driver for this device and performance problem will be wiped. Try nexus drivera for stock marshmallow. And i dont think fixes are as simple as that but it would work then cool. I think it is only stock which differs from original to B devices. Also brightness isnt a bug just remove adaptive brightness from settings>display it is not working becoz our device doesn't have any light sensor
