Permanent and annoying issues with CM7

Hello,
I've been using Cm7 latest KANGs since months, they're all good but there's ALWAYS been problems in every cm7 build that makes me hate this phone when it happens.
The problem is that they happen randomly with no apparent explanation!
problem #1
almost every week it happens that the phone drain battery very fast and gets a little hot. The reason is "suspend" process running wildly in the background.
What is it and why doesn't happen always? Solution : reboot, after it drained half your battery
edit : now "mediascanner" took the place of suspend
problem #2
every 3-4 days if you never reboot the phone it gets to a point where its slow and slightly unreactive. When you surf with Opera you notice a struggle to process data like something is using the CPU, the reality is that nothing is.
The worst part about this is when the phone is in that state and you do something that involves a cpu process you hear a noise form the speakers like an interference it's very difficult to explain. If you happen to listen to music in this state everything that you do makes the music lag like if it restarted every 1/3s of a second, like when you try to playback some video from a source that has a slower reading speed than the video bitrate itself. A jerky playback.
Solution = reboot.
problem #3 every month the phone (even on silent mode) "screams". :| that's right, from the speakers you suddenly hear random "leaks" of loud and high pitch sound things for NO REASON.
"problem #4" the front facing camera is just bad it doesn't adjust to the light with auto exposure compensation. It has very bad banding and digital noise things on the image. I thought it was a driver problem in cm7 but it happens in stock too. This problem didn't happen in the first nightlies of cm7.
Are those bugs reported?
I'm currently in problem 2 and I'll just let it do its thing just to see how funny the battery graphic will look. In 6h runtime I have "suspend" using the cpu for 30minutes and going.
I tried every kernel.

i have the same problem as you with suspend i dont know what it is, but anyways my battery is not that bad after 16 hours is still 58% medium usage.
we can try asking temasek if he has a clue.

I also have problem #3
very strange, happens sometimes even when the phone is on silent, and it's been sitting on my nightstand for 7hours without me using it (plugged in)
it also happens sometimes when it's not plugged in and I'm just browsing the web
(seems to happen more often when viewing video's)

What annoys me most its problem #1 . It's just unacceptable to have something for no reason draining your battery when you phone is sleep mode, even worse when you don't when it will happen!

#1 - I rarely have this issue but it doesn't drain my battery.
#2 - I don't hve this issue
#3 - I don't hve this issue
#4 - I use LG modded camera so no such issue.

Now I have it and I can't get it to go away!! It drains battery at about 10% per hour (without touching the device). What kernel are you using?
Can you link me the camera mod?

Got another for the list!
BBC iplayer !
On both the app and the Web page it works fine through the interface, the intro to your TV program works fine, then you get into the program and the picture is just pixelated rainbow mush! Lol!
Weirdly if you minimize the program and then resize the image it's fine!
What's that all about?

another one:
( I think its with every android version above 2.34)
if there are too many apps moved to sd card (about 50) phone works only till first reboot. once shut down and turned on again, phone keeps on rebooting. only thing that helps is putting sd in pc and delete some .asec-files from .android_secure-folder.

I had #3 before, I think it was around Temasek kang 1x.. After a dozens of flashes, I forgot it ever existed.

There's another one too which is important to save battery life: sometimes the wifi connection doesn't start until you go into the wifi settings. Meaning that if you are within the coverage you won't be connected to the wifi network until you go into wifi settings. This will drain battery because the phone won't turn off the eventual 3G active connection

I tried that but I what I meant is during video calls with skype and gtalk! It shows the correct exposure at the first second that goes into wrong mode.
BTW this phone has the worst ff camera, just bad bad bad quality

haha...the speaker scream at night....
just flash CM7 (Alien Revolution) this morning,
only some minor things found:
1. have to remove the latin.apk manually to against force close
2. can't use the original screen capture (HOME + POWER),
use the option by long press the power button for replacement
3. while playing "Let's golf 3", it got force close
clear the data of the game and it's solved.
4. 2 hrs before, the phone signal suddenly drop and disconnected...
just reboot and see whether it happen again...

Hi Temasek.. will this camera mod work with MIUI roms?

I have another problem on using CM7, it's the HDMI connection. My phone doesn't displayed on 1080p mode, pic quality is awful (my LCD TV is full hd capable).
And when I played a movie and throw it to the LCD TV on landscape mode, it displayed only for couple of seconds and then blackout. My phone continued to play the movie though. This is not happening in portrait mode.
On Optimus 2x stock ROM, it is possible to select hdmi resolution. How to do that in CM7?
Thanks!

no one of the problems here!
working fine and perfect with alienRevolution 1.9.1 ! Best ROM!

Problem #1 happend to me once, i was on ETaNa Kernel 0mb (i dont know wich version) and a Temasek Kang (think it was 61)
Never happend again. Now i am on ETaNa 32mb 18th Feb. and Temasek Kang 66, everything works fine for me.

I think the battery draining issue was just a bad RIL now battery seems as it should be.
I still have problem #2 though and I can't believe I am the only one experiencing it!
I made a mistake because I was powering off the phone at night in the last month but now that I'm keeping it on at night I can say it happens after 1 day of running time.
Basically when you start using it the second day the phone becomes unresponsive, go launcher EX keeps reloading icons very often, it takes sometimes 2-3 secs to open an app after you press on it , Opera keeps getting shutting down if you check another app for 1 second, when you go back you have to wait 6-7secs for it to restart. The situatios stabilizes itself a little when you keep using it (still not that snappy like at boot) but then goes back to the same sluggishness.
Juicedefender shows in the logs that "memory is low" and for how the phone acts it does look like it but I always have 80-100MB left and even if I kill every service running the sluggishness is still there. SO what the hell is causing it? Could this "suspend" be responsible for memory leaks? Again what does this suspend do?
Here's a screenshot for today only after the overnight recharge.
And of course the phone died while I was charging screen or phone wouldn't turn at all, apparently it charged to 56% and then BSOD

Just to make sure, am I the only one where suspend uses all the cpu?

i have also tryed cm7, its nice and stable but a little bug which forced me to change the rom, go launcher always restarts and i have to force close it and whenever i put some movies and images in sd card gallery doesnt updated it and shows old files only, thats y i changed my rom.

[Q] Question about Youtube stutter and Wifi connection issues

Guys i previously had stock v20e ..and i flashed stock v20q using one of the LG mobile update tool hacks i found here.It got flashed successfully. I didnt do a factory reset though.
Now though the phone works well..
1)The Youtube videos stutter a lot, restarting the phone fixes it.
2)Also the pressing the wifi button doesnt even show up my wifi router name to connect.Again,restarting fixes it.
(Both these problems occur after continuous uptime of about 2-3 days without power off)
What is causing this? I bought a dual core phone and I expected it to be much faster.Quite disappointed.
Guys is there any fix to these issues?Do you guys experience the same issues on 20q?

Many problems and glitches with droid 4 ICS. Any fixes?

Hi, ever since my droid 4 received the ICS update, ive notciced many bugs which interefere with me using the droid 4, and i was wondering if there were any fixes for them
Could these have been caused because of the way i upgraded the droid 4? I was too impatient to wait for the ICS upgrade to be released in my area when they started to send it out, so i ended up downloading it from here and installing it manually. could that be the cause?
anyways, here is a list of major glitches im experiencing
-touch screen refuses to work for no reason some times at random. it works on the lock screen and on the power off screen, but no where else. only rebooting the phone solves it
-when typing in a field in the browser, when i switch to a different field using the keyboard arrows, it copies everything from the first field to the second one
-browser randomly seems to hang indefinitely when loading a web page. i know its not a web connectivity problem, because when i go force close the browser in the app manager it works fine when i open it again
-sometimes the phone just freezes up entirely for no reason at all, and a hard boot is required. usually happens when using the browser
-sometimes bad lag happens out of nowhere
-the game plants vs zombies sometimes will freeze and reboot the phone by itself

At the risk of sounding like a Verizon CSR, have you tried a factory reset after the install?

I know a lot of people that were having various issues with the ICS update reported performing a factory reset (full wipe) of there phone fixed most of the issues. I've also heard wiping the sd card can sometimes fix issues. I doubt that performing the update manually is the source of your problem (I updated the same way) but you could also try fastbooting ICS to start fresh. Just make sure you back up anything you don't want to lose (pictures, etc.). Good luck!

I doubt your impatience was the cause of the slowness. ICS for the Droid 4 is nice, but is pretty buggy and slow. I've had all of the same issues you've reported including some random reboots. I use my phone a lot, and have a lot of email addresses and a lot of programs in memory constantly doing things, so I'm not surprised that my phone gets bogged down.
I recently loaded up Hashcode's CM10 port onto the phone and I'm telling you it feels like a whole new experience! So far, it's pretty amazing for me, it's been my daily driver for almost a week and I'm just checking for some updates now to fix a minor issue (my Wireless MAC address changes in this ROM). If you're a power user like me, you should really try to load up Safestrap and give AOKP, AOSP or CM10 a whirl!

[Q] Random Reboot after flash.

Since it seems Cyan has halted release of cyan 11 nightlies for the Atrix HD (indicative of what, I'm not sure), I figure it's worth solving this personal issue now; since it will most likely require another factory reset and I'd rather do it now.
Since day one of using custom ROMs, I've had the issue of my phone randomly crashing. Despite previously using only stable cyan releases, making sure to do clean resets (factory, dalvik, formatting system partitions,etc), letting the phone "stabilize" after installing (no clue what this means, but people seem to suggest just letting the phone sit about 10 min after flashing a new ROM, claiming a more stable experience), and even flashing a new kernel, I still see the same issue.
At this point, I've pretty much accepted that more likely than not, I'll have my phone randomly freeze and reset in my hands during basic use, calls, texting, internet use, listening to music, etc. Though clearing the Dalvik cache seems to quell the problem, it soon returns to the familiar behavior a day or two later. Any other basic solutions I might be overlooking? Suggestions, even obvious, very welcome.

CM11 switched to unified builds for the Moto 8960 family . http://www.cmxlog.com/11/moto_msm8960/
You can safely download a zip and dirty flash it over your current CM11 installation. At least that's what I did and I'm having possibly the smoothest experience so far on this phone/CM combo running Sat March 01 nightly.
About your crashes, do you get a phone freeze with signal loss before restarts? Do you always get a restart when the phone crashes?
Did you try enabling 2G only for a while? Do you crash while on WiFi?

You could also try another ROM such as Validus. I find the 4.3 release to be quite stable.

Thank you for the link to the new unified build. I've been busy with approaching midterm that I'd only heard of the new builds but didn't look into it personally.
As for the freezing. It's always been the same behavior: screen and all function buttons suddenly becoming unresponsive with no warning or change in signal (regardless of wifi or data use) remaining frozen for 10 to 30 sec, before returning to the unlocked bootload warning screen and the normal cyan reboot animation and normal lock screen after.
Everytime is has froze it will restart (i suspected a memory issue at one point, but after watching the memory usage long enough to see it randomly freeze but no change in mem, I doubt that it's directly the issue). I have not tried switching to 2g, so it would be worth a try. It will freeze regardless of whether wifi is off or on.
The only real "pattern" I could argue seeing is that it freezes most often during skype calls, while playing music (pandora and play music), and internet using browser; though it might only be because I'm actually paying attention to the phone while it is doing these tasks, I'm sure that it's probably freezing and resetting in my pocket thoughout the day. It will also randomly reset while looking through settings or non-data dependent tasks. Ironically, I've never had it reset on me while I was watching a youtube video. Go figure.

Any ROM, stable, nightly, cyan or other, with still see it start randomly freezing and rebooting an hour to a day after flashing.

-update*
After having switched to 2g signal instead of LTE, I haven't seen anymore randomly rebooting. I'm not sure if this was the issue but it's already been a day which is longest I've seen it remain stable.

1 Week later, back to the same behavior as before. Seems I might just screwed for having a stable modded phone.

[Q] 4X HD lag issue

Hello,
For the last 6 months or so, I've experienced many lag issues with my device. At the begging, I had a CM11 ROM installed on my phone, so I decided to revert back to the V20B official european firmware because I thought those lags were related to the ROM. But nothing changed, and as of today I still have responsiveness issues.
This lag issue appears from time to time, and makes my device basically unusable. It feels like the whole CPU is hogged by an application, or like I underclocked my device to 53mhz on purpose. During these lags, trying to wake up my device will take up to 5 seconds, and navigating the main screen will be nearly impossible. Also, my phone will get very hot which would imply that my CPU is indeed used by an application. Sometime the issue will disappear by itself after a few minutes, but I usually reboot the device which temporarily fixes the problem.
I have tried to disable LG MLT, and I think it helped but the lag still occasionally occurs.
I don't really use third party applications either.
I think these lags might be related to the Google Chrome browser, but it doesn't make any sense as it is an official app.
Anyway if any of you have an idea on how to fix the issue or how to find the application/service/whatever hogging the CPU I'd be grateful
Thanks !

I did experience such lags in CM11 after a few days of usage.But talking about stock, these freezes sound bit weird.You might want to check your installed apps.Download watchdog lite from play store and let it watch on agressive mode.Also check if your phone is hot when these freezes occur, might be the throttling kicking in.
I also experienced this kind of lags due to bad gapps I had installed back in the day, though stock ROM comes with gapps so it's not that.

Thanks for your reply,
I installed Watch dog lite and I'm now waiting for an alert. I hope it will give me the name of the culprit

If you are rooted which i assume you are. You can try app from playstore called "lagfix" (fstrim)
Sometimes really helps. Sometimes it doesn't
