Init 100% CPU utilization bug discussion - Nexus S General

I'd like to get an idea how many of Nexus S owners are experiencing this bug and any thoughts and suggestions you have concerning it. I'm currently on 2.3.2 with stock ROM & bootloader (rooted however this issue occured prior to rooting). I've performed a factory reset (settings -> privacy method) which did not get rid of the issue.
The current solution to this bug is to enable USB Debugging. This does stop init from using 100%, however it introduces another bug. I've noticed that often times when I press the power button on my Nexus S to get it in/out of standby it will vibrate once, followed by a period of 2-10 seconds of extreme slowdown (to the point where I can't get out of the lock screen) until the phone vibrates twice, returning to normal speed. This only happens when USB debugging is turned on.
I'm really hoping 2.3.3 introduces a real fix for this problem. Otherwise I will be performing a bootloader unlock/relock to completely wipe my phone, if that doesn't work I will be going through the repair process if possible.

[Q] Serious Touchscreen Lag Issue [UPDATED]

First of all, sorry if this thread is out of place, but I'm not sure where else to turn.
My HD2 worked terrifically with FroyoStone 3.2, Hastarin 7.6 up until last Wednesday (5 days) ago. Then I started to experience, and have not been able to fix, serious TS lag issues.
Symptoms: I hit the unlock button, swipe to unlock, and the touchscreen will be responsive if I KEEP using it...if I pause for up to 3 seconds, the screen is no longer responsive. I have to relock the phone, unlock, and then swipe again to get it to work.
The touchscreen works perfectly fine in Windows Mobile 6.5. (Energy 2361X)
Attempts to fix: I've formatted the SD Card inbetween trying all of the following items-
1) Switch to MDJ ROM with MDJ kernel
2) Switch to Bluetopia ROM (0.5, 0.6 & 0.6.1) with Hastarin 8.0 OR 8.1
3) Switch back to FroyoStone 3.2 with kernel that comes with it
4) Update Radio ROM
5) Update to new Energy WinMo ROM -- after running Task 29 first.
Today, I purchased a new SD Card, loaded it with a clean install of Android, still have issues.
Also tried:
1) Turning off all LED notifications
2) Disabling Auto brightness in WinMo and Android
3) Disabled Screen Auto-Rotate
Honestly, I'm all out of ideas, and I hope someone in the community has a way to help out. I find it so odd that the touchscreen works great right after a "wake-up" as long as I keep it constantly stimulated...then fails to respond if I let it sit for more than three seconds. Is this a polling issue?
All ideas are appreciated. Thank you
UPDATE:
Followed another thread that suggests using the exact same WinMo ROM as the Builder -- matched my ROM with cmylxgo's WinMo ROM (author of Bluetopia) after another Task 29...no fix.
More Information
UPDATE 2:
Also tried 32K clusters and 64K clusters when formatting the card. Problem exists with either size.
There are G-Scripts to disable the G-Sensor and then re-enable it without rebooting.
If you want to jump to the extreme and want to remove all the sensors entirely.
Code:
su
rm -rf /system/lib/hw/*.sensors.so
Terminal
Thanks for your quick reply.
Unfortunately, I'm not the best with working with Linux/Terminal commands -- I tried typing in your code, and it returned that there was no such file/folder as -rf, and then I removed that section, and it said that it could not find the system/...
So obviously, there's something I'm missing, or an error in the syntax, that I cannot debug.
Any help is appreciated.
Are you having any data freezes or are you on an area with poor to no signal? I get really bad system lag when I loose signal while my phone is trying to download. Ppp will freeze and the phone will be unresponsive till reboot. Only way I avoid this is to turn off data if I got into a building I know I will loose connection in.

Updates
Thank you for your reply --
I checked into the disconnects being an issue by enabling Airplane Mode and seeing if I still had the same results, and unfortunately I do. I tried by disabling the Wifi and Mobile network separately, and still same issues.
But, here's an update on the issues:
Installed TYTUNG's NexusHD2-FRG83 V1.6, and this thing is very, very lightweight. Great battery life, great data (went to sleep, woke up, and not only was my phone still on...but I didn't have to reset data to check email...nice). The issues still remain. These are the newest things I've tried:
1) Remove Boxwave screen protector
2) Run from Airplane Mode.
I did however notice something really, really important: when the screen freezes, if I simulate a multi-touch gesture (pinch to zoom, etc), sometimes it wakes up! This is not a guaranteed thing (like 60%), but definitely something to work with.
Also, I noticed that one time that the touchscreen stopped responding, I tried the multitouch, no help...but I stayed on it. Multitouch tapped like crazy for a solid 6 seconds...then tried to shut the screen off -- and that button didn't respond. It was as if I saturated some bus of some sort that it had to clear out before it could finally shut the screen off.
Finally, I've noticed that the screen just needs to shut off for the touchscreen to unfreeze -- not go into a full lock situation. So, if the screen goes black, and I hit the lock key immediately, it'll unfreeze the TS.
Thanks to everyone who is trying to think of an idea!
i seem to be having the same issues as you right after i wake the phone up to unlock it. locking the phone is a habit for me to try and save as much battery as possible and also to not press any buttons while in my pocket.
im running a cyanogen rom and i changed the setting to allow me to unlock the phone by pressing the center windows key. i noticed that when the phone will not allow me to unlock it i can press the menu key and unlock it but i cannot use the touchscreen at all until i relock and unlock.
sometimes i have to do this a few times before the touchscreen comes back. i was thinking it could be my sd card but this started to happen today. i have been using android on my hd2 daily for the past 12 days without any problems. its weird that it started all of a sudden.
so it seems we still dont have a fix for the touchscreen freeze yet, right ?
Same problem here
Hi, I am experiencing the same problem.
Tried few versions of Android, The same problem repeated itself.
So I had to return to WM6.5 - there it works good. Only I have to reset the phone twice a day :-(
Hope someone will find brilliant solution for the sad problem that prevents using Android...

[Q] Unable to unlock & glitched graphics - SDSL 4.0

I've got a few problems lately and I have no clue how to go about fixing them.
I'm not sure when it caused the problems, but I'd like to keep settings and apps that I've gotten now. I see constant factory resetting as a workaround rather than a fix. The last thing I did before I got these issues was plugging the phone with an USB cable to a Windows XP computer without installed drivers for the phone. There was a movie running in the background in MX Player and I noticed that I'm unable to unlock the phone.
First off, the lockscreen is bugged. When I try to unlock the phone the screen stays blank, but the button LEDs are glowing and vibration works if I hold the power button, suggesting that the system is still working. I tried turning the CRT animations on/off to no avail. An interesting detail is that the lockscreen that appears just after booting up the phone shows up and works fine.
The second problem I have is some of the GUI being glitched. It occurs to for example the startup lockscreen and power menu, as in the attached picture.
To make sure this wasn't a hardware fault I did a complete reflash of the phone using KDZ updaters and there were no glitches in stock ROMs. After installing back the recovery (Clockwork 6) and restoring the backup of this SDSL4 the issues are still present.

[Q] Screen Black / Auto Powered Off Frozen?

I seem to have the most bizarre issue that started happening last night. Ive been running XNote v3 and AEL kernel fine for a long time now.
Whenever my screen turns off (when i hit the power button or the timer runs out to turn screen off) The phone will after x minutes, either auto reboot or turn off (without shutdown animation)
It then remains off black screen and you do not know this unless you try use it again as you cannot power it back on at all, no sound and the phone is off as if you call you get voicemail.
Anyone any ideas what it might be?
I cant work out if it is software/ hardware related as nothing has changed software config wise and i have not done any updates.
I was thinking of maybe going to a stock kernel and see how that lives.
Its very easy to replicate and the only way to bring the phone back to life is to take the battery out.
If i am using the phone its perfectly fine, no reboots, freezes etc. Its only when screen is off.
OK since no one replied back but a lot of people viewed i thought i would provide an update.
Since factory resetting it
changing battery
wireless charging
removing sim
removing SD card
changing rom
changing kernel
changing back to stock
remove root
boot loader etc
all failed! a new replacement motherboard fixed the problem. i am unsure what caused the fault as it was working perfectly for over a month.

Note 4 freezes while charging after lollipop

I tried posting this in the Sprint thread but haven't gotten any answers yet so perhaps I'll have better luck here. I pasted both posts to show the initial problem and what I did (essentially I factory reset). I'm still having the same problem where my phone will freeze while I'm charging it (about 2-3 times/week) requiring a battery pull. Anybody else seeing this problem or have suggestions on what I should try? Thanks.
-----------------------------------------------------------------
Twice this week my alarm didn't go off (luckily I set a backup today) because sometime throughout the night something happened. When I woke up the phone was frozen on the yellow Sprint Spark startup screen. I needed to pull the battery and everything started up fine. I updated to Lollipop about 2 weeks ago which is where I'm guessing the issues stem from.
Is there anything I should try other than restoring to factory and starting over? I'd prefer to not have to wipe everything from my phone but these issues are becoming problematic. I am not rooted.
Thanks.
--------------------------------------------------------------------
So I ended up doing a factory reset and while the phone certainly started running faster with better battery performance after the reset I'm still having this issue. I would say it occurs 2-3 times a week. It has only occurred overnight which is typically when I charge my phone so I'm pretty sure it is related to being left connected to the charger. The majority of the times I will wake up with a dim yellow Sprint screen and everything else frozen though occasionally the screen will be black with the led notification light red. In both situations the screen will not respond to any button pushes or holds and I need to pull the battery and then everything will start up fine.
Does anybody have any suggestions here on what I should do? I guess I can try and restore one more time and see but I don't really know why it would be different and it is certainly a pain to keep restoring the phone and losing all my settings. I definitely don't want to root now since I believe that voids the warranty and if I can't figure anything out with this I'll certainly be requesting a new phone from Sprint. Before I start dealing with Sprint though I thought I would check here first. Through all my searches on the internet I haven't seen anyone else complaining about this problem.
Thanks.

Hi there. I have a Canadian Note 4 (W8) with Bell, and I am having identical issues.
While charging over night, I find my phone stuck on "Samsung" logo, with the bubble animal still running. Holding down the power button does nothing and the only work around is the battery pull. I noticed that it also gets warm (assuming from the screen on time?)
First tried cache wipe - no fix
Factory reset - no fix
Cache wipe again - no fix
Aaaand today I came into work late

Did your issues first start after you upgraded to lollipop?

Definitely after the upgrade.
While on KitKat, it never happened (1 month ownership). But after upgrading to lollipop, it has happened 4 times (6 nights since lollipop).
Have you figured anything out with your situation? Woke up this morning to my backup alarm and the Yellow Sprint screen on my phone.
I guess I'll have to try another factory reset and if it still happens try and get a replacement. It just doesn't seem widespread enough of an issue to be a software bug with 5.0.1.
Very frustrated. I did another factory reset but the issue still plagues my device. It still only occurs once or twice a week but when I hear my old clock radio alarm in the morning I know when I look over I'll see the yellow frozen Sprint Spark screen. I am completely out of ideas and guess I will need to have it replaced under warranty. I'm hoping Sprint won't give me a hard time as this will be very hard to demonstrate.
It definitely appears to be a software issue as it never happened before I upgraded to Lollipop but there must be more to it or others would be complaining.
If anybody has ideas please let me know. Thanks.
Response to Note 4 Freeezing while charging
I have found that after turning the quick charge feature off the problem is not happening. Hopefully this is fixed in 5.1
I'm having the same issue even after turning quick charge off..def a lollipop bug, never experienced this on kk.
I know its not the BEST option, but after taking the update to lollipop, sometimes left over kitkat files can make the system poop out. Sometimes a factory reset will take care of the leftovers. But of course, then you have to set your phone up again
If you've tried this or plan to to, let us know the results.
(When i first took the update, my heartrate monitor sensor was always on, so i did a factory reset and it fixed my problem).
Solved with workaround!!!
I faced this "sleep of death" too after updating to Lollipop. I had to pull out the battery almost every time after charging. Very annoying! I noticed though that my phone never froze in my car while charging. Thinking about the difference I realised that I keep my phone awake in the car while charging using Macrodroid (which I love anyway to automise all kinds of things). I made a simple macro which keeps my phone awake while charging and another one that returns the phone to normal while on battery.
While charging: Trigger: Power Connected; Actions: Keep Device Awake enabled & Screen Off, Constraints: None
On Battery: Trigger: Power Disconnected; Actions: Keep Device Awake disabled & Screen Off, Constraints: None
Off course there are alternatives available to Macrodroid that should be able to do the same.
My problems are solved, with and without fast charging. I hope this will help some of you as well.
same problem here
Ive tried turning off fast charging option on the powersaving mode
And also tried the option on developer mode, the "keep device awake while charging"
And even flashing dofferent firmwares from sammobile through ODIN and installed custom roms. These options doesnt resolve the issues on freezing while charging..
I think turnong off your device while charging is the only option..
Im using note4 N910C..

Thanks a lot, Mate. I'm trying your workaround now. Will report later if it works on my phone. BTW, so, are you sure it is a just a system issue? Definitely, isn't a hardware problem? Did you fix it, after your post -a month ago-, installing, for example, lollipop 5.1.1 or Cyanogenmod 12.1? I'm on 5.0.1, SimpleRom V4. Of course, mi device, N910C, is rooted.
Thanks again.
With lollipop 5.1.1 the problem is solved for me, even without this workaround.

I'm having similar issues as you guys. I found out that my phone will only perform normally when I charge it with my laptop USB port which I think is around 0.5amps. Anything above that, even a 1amp charger would cause the phone to freeze, reboot and turn off and not turn back on. The phone has been in repair 4 times and the problem is still there. Now every night I'm forced to charge my phone with my laptop which takes an age instead of the fast charger that came out of the box.
Currently my phone is still freezing and rebooting when I'm out and about and the only way I can get it to perform normally is when I plug it into my laptop. This normal functioning would only last whilst the phone is plugged in.

Screen issues

Hello folks, I'm having annoying issue with the screen so wondering if anyone can try to help me or has encountered similar issue.
The issue is that the screen wakes up randomly without touching it, as the power button was pressed (without notification). This started after updating to april rom.
Here is what I have done so far: turning off/on ambient display, turning off/on adaptive brightness, remove sd card/sim card, returning to march update doesn't resolve this, factory reset, flashing the latest stock 8.1 beta rom...
Interesting thing is that the issue is NOT happening when booted to safe mod, which makes me believe that this isn't hardware failure ? Or am I wrong ? Anyone with an idea how can I try to resolve this ?
Application can cause wakelocks - wake phone's CPU to do its work or just turn on screen. Especially 3rd party apps from Google Play cause this, maybe there is an app causing your phone to turn on. Use BetterBatteryStats (with ADB commands) to see which apps wake your phone.
