[Q] Kernal problems Captivate I897 - General Questions and Answers

Running into a strange problem with flashing kernels on my cappy and i was wondering if someone can shed some light on what i'm doing wrong. I'm running phoenix 4.5 with stock speedmod kernel with lagfix disabled. Whenever i enable the lagfix OR flash a faster kernel such as sucker punch or glitterballs, the back button randomly activates without me touching it which is annoying to the point where i have to flash back to stock and disable lagfix. Whenever i run a kernel without the lag fix, i have no back button issues. I'd like to figure out a fix for this problem so i can run the powerhouse kernels without my back button going haywire. I'm a noob to XDA and have tried searching for a solution but i haven't found one yet. If one has been posted on this issue, please excuse my noobieness. I'd appreciate all the help i can get

Theres an app to change the physical buttons behavior, so you can replace the back key function with another button, but this sound like a hardware issue, some captivates also suffer from it.

Wow so even after flashing back to stock you're still getting black screen? I've seen the black screen a few times with miui but not everytime. I was hoping it would be fixed with the final v5.
thats weird. the first time a flashed Miui I had that same problem. I just reflashed the same rom and the problem went away. I have never carried the black screen through multiple roms.
Even I flash back to the stock rom by RSD the black screen can't fixed. I already replaced the camera module but not fixed.
Do you use autokiller memory optimizer? I got black screens when I set it above strict. If you do maybe youd want to lower those settings.
I didn't install the auto killer, But even i flash back to 2.1 stock rom without any tweak apps,it still can't fixed the black screen
Hmm, same issue in several ROMs, sounds like an hardware error.
I have found the following in Loyat Forum:
(http://forum.lowyat.net/topic/1667176)
Help! My camera shutter suddenly closed up and can't open anymore. Is this normal or my phone is screwed?
This is a known issue for xt720. Not all of them though but quite a number have experienced it already where the shutter just completely shut. There's nothing much can be done other than sending it back for warranty... OR you can try this trick. Get a magnet and put its South field close to the shutter. Apparently it will open up. Not sure how true is this but yea.... better than dismantle the whole phone just to find out you really screw the phone up for good...​
Maybe this could help...

Green Screen/Artifacts - Hardware or Software problem?

Hello everyone,
I've been having quite an interesting issue on my NS4G. I'm currently running the latest available CM7 nightlies/gapps, as well with Pete Alfonso's kernel. The underlying system in the phone (radio/etc) is all running the current latest available from Sprint as well.
Now the issue in question, I've been having an issue that seems to be occurring more and more frequently on my phone. Now because I am already running a custom ROM and not just stock, this makes me unsure if the issue is coming from the software, or if there is an actual hardware issue with my phone.
Occasionally (I would say as infrequently as once every 2 days or so) when I unlock my phone with the power button, for a split second after the CRT animation I see my phones screen as all green (with a hint of purple), almost the color you associate artifacting with. Now I am not overclocked, but I am running this custom kernel. But the thing is, I'm not 100% on this, but If I remember correctly I do remember seeing this issue on other kernels as well before (I've been running Pete's for some time now).
I also occasionally experience issues with lets say finishing up a phone call, and my phone may lock up with that green screen w/ purple, and then CM7 will automatically reboot the phone for me. I've also experienced my phone rebooting into "Safe Mode".
Essentially what I am wondering is if anyone can shed some light, are these just software bugs that I am running into that other users are experiencing as well, or is this an issue with my phone?
Thanks everyone!

go to the main settings, cyanogenmod settings, display.. turn on the screen off animation. then go back to cyanogenmod settings, lockscreen, delay and timeout, turn both screen timeout delay and screen turned off delay to immediately. that should fix the green screen.

[Q] Multitouch Keyboard Issue

Anytime I alter the lock screen on my Inspire 4G, I experience multi touch issues. It's only when using an app like Widgetlocker or altering the HTC_Lockscreen.apk. The issue primarily manifests itself when using the keyboard and typing too fast. Keys will then no longer work until I turn the screen off and then back on but then the problem can be re-triggered by typing too quickly.
I run the stock rooted with no kernel alterations.
I really don't care much for the stock HTC lock screen and would like something else but this even shows itself through other roms that aren't based on a Sense framework.
Please let me know if you have any type of resolution? Perhaps a new kernel for a stock rom could resolve this? I don't know much about kernels but don't need anything special. I just want to resolve this issue make my lock screen more efficient.
ive had that happen too me also i need help to fix it, so it would be cool if someone had the advice to fix this.

Music Stutter

Hi,
First of all I just want to say thank you to all the good people at xda. I am very new to Android and I have found much more useful things on here than anywhere else.
I recently got a Milestone XT720. It was running on Dexters Froyo. It had a whole bunch of issues but most were fixed when I finally decided to try to flash a newer ROM (First time) and went with the CyanogenMod 6.3 RC3 thanks to a Tutorial from this forum.
The only issue that remains now is that whenever you press the power button to return from sleep to just check the time or notifications the music stutters for just a millisecond. And then does the same when going back to sleep again.
I have found that turning off the auto rotate screen option will stop the stutter but that's not really a solution as much as a bad compromise.
Does anyone else have the same issue? Could trying a different rom make a difference? I am really starting to warm up to the XT720 and would really appreciate if someone could help out with this!
Oh and possibly worth the mention is that I flashed the cyanogenmod over Dexters and did not go back to stock in between. I have also tried the supercharger script on aggressive without any luck.
Thanks all!

Music pause is common problem on our devices. AFAIK turning off the auto-rotation sensor is the only solution. I have tried several ROMS but it happens with all of them.

[Q] Pixelated flashing lines on display screen

I've been having screen/display issues (not the yellow hue and separate of the touch screen sensitivity problems). Every now and again, I get flashing, pixilated horizontal lines. I don't see any dead pixels and when it's not blipping the screen seems to display flawlessly, so I'm not sure if it's a software issue or if the hardware is failing. Also it's not isolated to one particular area, it jumps around. Anyone have this problem? Any fixes? I haven't been able to find anything on it. PLEASE HELP. Below is a video of the problem.

Are you completely stock? Any custom kernel? Any rom?
Usually it's a kernel issue - tearing, but it's only present on custom kernels (never came across on the stock cm11 kernel). You might wanna try a different kernel though, if you're comfortable with that.
I have the same issue on my stock rom with stock kernel. the only thing i have changed was the developer options. i changed the screen animation time.

Was it working before those changes?

Perhaps this might help?

I had exact same issue during recording a video yesterday night !! I am latest mahdi and latest franco...
Funny thing is it went away once i exited the camera... what rom and kernel are u using ?
I've been having the same issue too. I don't have a solution for you, though. I haven't been able to find much about it.
Same issue here, stock all the way, only been since latest update. The update didn't flash properly, it gave an error stating it couldn't be located but i went through the files and it was there and then upgraded OK
I had the same problem. Selecting "Force GPU Rendering" in developer options cured it.
i have stock everything. i'm not rooted.
a reboot fixes the problem temporarily. shoot, all the issues i've ran into with this phone thus far (like the GPS not locking on) is fixed by a reboot. i know a reboot is good to do every now-and-again regardless, but having to do it constantly to fix issues is the sign of a failing device and is very annoying; it shouldn't be something you have to do with a brand new device.
i am facing this too randomly. Am on rooted 38R with Franco kernel. Rebooting is a temp cure but it will frustrating to keep doing it.
This happened to me after getting 38R. Fortunately it hasn't been back since a hard reboot. It would show up on Youtube & when dragging down the notifications area.
I had this today on PAC ROM. When I unlock phone and lock ring animation dots flash up made lines come across screen not sure what it was or why. Just rebooted phone. Back to normal. But trying out vanir later tonight try something abit different.
Also experiencing this here.
Stock ROM, clean 38R install.
Stock kernel.
Rooted, with a few xposed modules.
Started a day or two ago. Haven't found a way to recreate it. When it does happen, a reboot remedies it, but only temporarily.
I will attempt to screenrec it the next time.
I find it interesting that I only see mentions of this starting recently.
Same problem for me since the last update. Restarting the Phone solves the problem for some times. Maybe a driver issue?
Glad to see that it is not a hardware issue.
Same here
Same here, mahdi-2.8-bacon-20141001 ROM, enabled "Force GPU rendering" in Developer options, let's see if this comes back!
I have the same problem on latest cm nightly with stock kernel. And dev options works sometimes but it resets on reboot and my phone reboots randomly all the time. I'm starting to hate this device
Sent from my A0001 using Tapatalk
I also have the same issue on Stock 38R update + franco kernel r27
It happens after the latest kernel update, before I never had this lines.
Lucky for me I don't have any reboots now but I fear that will come to pass as well.
Got the same problem with Mahdi Rom 2.8 - 20141016
Will be solved in Franco Kernel r28,he just confirmed this on his kernel thread.
Sent from my OnePlus One using XDA Free mobile app
same issue here. i have to reboot. its happened on stock and AK kernel. will try enabling force gpu rendering and see if it comes back
