System Killing Launcher on every app launch!!

Hi!! I have a problem, I'm currently Running Darky's 10.1 with dark core 2.6... Everything is smooth and snappy, however the system keeps killing my launcher everytime I launch an application whether it be a game, browser, news app... Whenever I exit the app the launcher reloads and it makes the phone really really slow and laggy for 10-15 seconds...
I currently using ZEAM launcher, not sure whats causing this, i've been using this launcher since its launch and only had this problem when i was on stock froyo...
Any ideas what can be done to fix this issue...
Thanks!!

Same problem here.
I am on GigerReal 7.1.3 and the worse thing is when it you try to make a phone call and the bloody thing just restarts the phone every third key pressed.
I can only call using voice calling when this happens...
I am using LauncherPro but it also happens in Ginger Launcher and TW Launcher 4.5

Just out of interest guys, how much free memory is showing for you in Settings > Applications > Running Services ?
I am running stock JVQ and although the phone works fine after initial boot (with around 180mb free) this number seems to drop over time and results in any new application clearing any other app from the memory. This even meant that if I got a text message while using the web browser and replied to it, by the time I went to return to the browser it had to reload where I was from scratch. It was also clear that after playing a game and returning to the home screen, even this was having to reload and "redraw" again.
That in itself is a minor annoyance but eventually it seemed to get so bogged down the whole system froze with the "black screen of death" and I had to do a forced reboot. I'm aware, of course, that JVQ is not an official release so it's not fair to be too harsh on Samsung here...

I seem to have a lot of memory free. It happens after the phone has been up for some time.
I noticed that launcher pro was reloading the widgets every time it starts. Also i seem to notice that it happens when you dial a couple of numbers and it starts giving you suggestions from the contacts. So it could be contact related?

This is the same that happens on my system... The launcher just reloads all the widgets everytime I close an application... the amount of ram is always close to 243/337.. So its close to 90-100 mb free, which is enough i suppose... Still the launcher just reloads everytime an app is closed... Its really getting annoying...

basicly you must set HOME_APP_ADJ to 0 making home app unkillable =)
am not sure but probably do that
/data/local.prop -> add such line ro.HOME_APP_ADJ=0
and restart - have not tested just pure theory (the .prop location)

Actually, putting the value as 1 worked better for me. My launcher so far has not been killed even once.

ya 1 should work flawlesly
0 is making it bulletproof/unkillable at any state
but 1 should be safest value

I think Spare Parts allows you to adjust the task killer's sensitivity. Maybe have a play with that and relax the settings.

Hi Thanks for the advice, however i'm not sure how to set these values, Is there any tool that I can use to do that??

spare parts at least free one does not have such option
also this is not about adjusting memory taskkiller options
not the one that you can setup with this useless juwe script for example
different thing

Attached is an APK which adds that line. Make sure you're rooted first. I wrote it in the past 10 minutes, so it's very simple and might crash, but it did work for me.
Just install it, launch it, confirm root and then watch out for a small message. If successful it will directly ask you to uninstall it. Reboot, and done.

there is also ro.HOME_APP_MEM that can be changed to 4096
to follow other oom_adj=1 settings =)

@martino2k6
Thanks a lot dude... The apk installed perfectly... I'm already seeing improved performance from my device... The launcher hasn't been killed once since the install...
Thanks again for all your help... appreciate it...

Try changing the lowmemoty killer setting to something less aggressive. Your phone is trying to keep too much free memory so has to kill off apps.
Download Galaxy Tuner (using memory manaber option)and set the application cache values to the new samsung default as follows:-
fa=10 MB
va=16 MB
ss=20 MB
ha=24 MB
cp=28 MB
ea=32 MB
Make a note of your current settings in case it doesnt help.
You can also use Galaxy Tuner to set JEWE's file system cache
, settings are:-
SWP: 50
VCP: 10
DEC: 5
DWC: 10
DRA: 90
DBR: 5
These work well for me so give them a whirl, you can always put the values back to where they are now.

mate the problem is solved already - please read dont spam those juwe crappy values ok ?

Ok, cool

High IOWAIT

The issue started when rotating my Nexus 7 from portrait to landscape mode. I have the lcd_density set to 177, so the homescreen rotates. Today, the homescreen icons started disappearing for 20-30 seconds when rotating. I enabled "Show CPU Usage" in the Developer Options, and noticed that the IOWAIT (blue bar) is really freaking high whenever I rotate. So I connected through ADB, and ran TOP. IOWAIT was shown between 33% and 77% right after rotating.
So I ran "
Code:
echo 1 > /proc/sys/vm/block_dump ; cat /proc/kmsg
" to view what was causing the iowaits. It appears that "launcher-loader" is writing a ton of data.
I am out of ideas of what to do. Anyone have suggestions?

Don't use the dpi change. Just use paranoid android for proper tablet mode.

I don't think the LCD Density is the cause of the IOWAIT. I have been using it at 177 DPI for months.

Maybe it's related to the LAG issue? How much do u have in storage?
I met same and turned out IO performance so poor due to low storage (<3G)

You know, it did get slow once I went under 3 gigs free. However, I have now deleted stuff, and it is back up to 4.7 free, and IOWAIT is still high.
EDIT: I installed the Franco kernel, hoping that would fix the lag issue, but it did not. I am starting to wonder if the flash memory is going bad.

if you check the LAG thread, you should find once you get below 3G free, it WON'T come back even you free some space, a factory reset does work however.

Crap. That does not make any sense!
Thanks though, I read through a few pages of the LAG thread, but at 48 pages long it is a lot to catch up on.

Google is already investigating this. Maybe there will be a fix...

Did u disable fsync?
Installing Franco kernel by itself won't fix the issue. U need to install then disable fsync using the Franco kernel app or a script.

Hmm, the kernel said it was disabled by default, so I didn't even bother to check. Lag issue fixed. Just am afraid about this data integrity issue... oh well.

It used to be disabled by default, but was changed in a future update to be enabled by default. Can be disabled with a script:
Code:
#!/system/bin/sh
echo N > /sys/module/sync/parameters/fsync_enabled

I ended up just doing it through ADB to test. It feels good to finally have a fast tablet again.

To all people who has the memory managment problem

My Moto G 2014 xt1068 did not perform well for a long time. I tried editing the lmk values with just a little improvement, I also added ro.MAX_HIDDEN_APPS to Build.prop with a value of 16. But with this, the phone tends to work ok until RAM gets full. Then it hangs for a lot of time and the screen goes black. But yesterday, without almost any hope I went to Kernel Adiutor and lowered the Z-RAM to 0. And man, that was awesome. Now my Moto G is another phone. I'm almost sure it's not placebo, because now I can listen to music while I'm navigating on chrome and I have Facebook Messenger chat heads active, and before that was just not possible. So, if you want to give it a try, let me know if it worked for you and I hope I helped!
I'm on Minimal OS with the last update and no kernel added.

That's a strange behaviour: zRAM usually improves the performance of the device. It's used like a swap disk but obviously it has better I/O speeds; on the other hand the workload on the processor is a bit heavier. Just one question: what was your previous zRAM value?

It was at 250mb, the default value.

It's supposed to help if it's enabled but oddly enough, it's not even enabled on some phones. To verify it's even enabled, in terminal emulator type 'free -m', and the swap column has to be non-zero.

I have xt1068 and my default value was 160.After I set it to zero and rebooted I can watch video in chrome and the play music is not closed, only paused.

How do I set it to 0? What options do I have to enable?

Normally in the kernel settings with something like kernel adiutor.

the setting won't stick for me in Kernel Adiutor, it keeps resetting back to 160

I tried that out, the setting stays on 0 when you select "apply on boot" and reboot. But in my case it made the multitasking issue even worse, it is much better with the zram setting on 250 which is the default value of my kernel.

Yes, i changed it to 0 and the performance was worst, launcher resets, lags with camera and chrome.. changed it back to 250 and it was fine!

Nova 3i Bugs

Hi all!
I am a Samsung user genuinely. But since my last phone broke down, it broke my budget too.
Got Nova and here are some bugs.
1) Bluetooth speaker issue. the sound is way late than the video. (Edit: Fixed by going in developer options and changing "Bluetooth audio codec")
2) Camera is not having any kind of stabilization.
3) It hangs like hell and u r not left with any option. Not even restart.
4) Not the fastest 4gb ram phone.
5) The interface of the phone is laggy af ( can be fixed by installing 3rd party launchers).
6) Processor temps are never lower than 60 degree C. Idk if its fine or not but antutu temp sensor always shows it in red text.
These are the ones I could find... tell if u have any.. or at least have found fix for any of them.
BTW...
Today got an update of 288MB which is currently downloading. Hope it fixes some bugs.

Lol I kinda like mine, except for a few things I guess but I got it for a good deal, well I reckon anyway - $380 NZD.
What did you replace it with?

Hello! These issues, especially the Camera app being buggy, are common.
The performance issue, please go to settings > Battery > Battery Usage and see which apps are using a lot of background usage, then click on the app and there's written 'App Launch', click on that and toggle off the 'Manage Automatically' and also toggle off all of the toggled on things to prevent the app from consuming background usage.
On this device you can also disable/uninstall many apps that if u dont need, please do so, here are some list of apps you can disable which would improve performance:
1. Gmail (replace with another mail client like FairEmail)
2. Youtube (replace with another application like NewPipe)
3. You can also disable playstore and the main Google app.
4. You can also disable Google Play Services, this consumes a lot of background usage, more than HMS! You can replace playstore with F-Droid and you can get FOSS apps.
5. Replace Facebook with Frost for Facebook, or disable background access to it from the previous performance issue guide.
I am not getting performance issue on mine, so make sure u check which apps are using background/battery usage a lot so you'd find out.

Miui 11.0.3.0

I received it today on global version.
Turned off digital well being and other unnecessary stuff but battery drains noticeably more than MIUI 10.
Any advice?

I had the same after Charge to 100% is everything good maybe a little bit better as on 10

Some people say that MIUI 11 enables Autostart for every app, take a look at that in the settings and keep enables only the apps you need.
Actually, I noticed that battery drains a lot less when screen is off, which is a very good thing.

the only one issue i had with miui11 is digital wellbeing, i can't disable it.... but nothing to worry about, root access did the job!

I'll try charging it to 100% and see if there is any improvement with battery.
I didn't see any change in autostart setting on my phone.
But what I noticed is USAGE ACCESS setting changes back to ALLOWED for digital wellbeing, system launcher, Google play services, and device health services after I disallowed them. Very annoying. This is under Digital wellbeing -> turn off usage access -> then disallow for all the apps. Not sure if it gets reseted for above mentioned 4 apps after reboot or after sometime. Is root only way to fix this? Prefer not to root.

You can remove it via adb, ,,

I've figured out auto start in issue isn't the ones under permissions. It only shows up after you run security scan and click on solve problems. I had 26 apps which were allowed to auto start. None of them were allowed under permissions. This doesn't make sense to me. Anyways I disabled all 26 auto start. Hopefully this solves the heat and battery drain issues.

Even after disabling all the auto starts, battery drains quicker than miui10. I thought better battery performance was one of MIUI 11's selling points. Not happy with it at all.

I'm thinking of deleting TalkBack and digital wellbeing using adb. Had anybody done it? Safe to remove them?

Yes I've done it, I removed digital wellbeing and some other apps and all its ok, I'm getting about 10 hours sot right now.

How you have 10 hour sot ?????

Well it's reverse on my side.
After downloading OTA package from xda of Miui 11.0.5.0 and I updated it. Now my battery drain is completely stopped and In miui 10 my battery was draining so much but now it's gone.
