[Q] Cyangogen mod On HTC Sensation - Screen Flickers Badly - General Questions and Answers

I am posting a new thread here because it says I cant post in the specific rom's thread.
I've recently flashed the Cyanogenmod 10.1 rom on my HTC Sensation and it works fabulously when it works.
I have the latest build but I'm experiencing a very intense screen flicker several times a day that requires I pull out the battery to fix it.
A normal reboot or power down/power up doesn't seem to fix it. The flickering will continue after reboot unless I pull out the battery.
The screen flickers and then goes totally black until I touch the screen again, then it flickers enough that I can see the content on the phone.
But the moment I release the screen it goes solid black again.
I flashed my phone back to stock before I installed the rom. I'm kind of a noob with all this - I flashed my last HTC HD2 phone to a separate XDA rom, so I have some experience, but not a whole lot. I may seem clueless on some things but I CAN figure it out with some clearly-written steps.
This seems to be a known issue but I haven't seen anything suggested that has fixed it for me yet.
If anyone could help, I'd appreciate it! I love the rom but the screen flicker happens sporadically. Sometimes it won't happen for hours, sometimes it will come back fifteen to thirty minutes after I power back on.

Try this rom. It's a modden version of CM10.1, specificly tweaked for the Sensation, running Android-4.2.2. I'm using it for a few days now on my own Sensation and I really like it.

That's the one I used. It's perfect except for that horrible screen flicker.
Still waiting and hoping for an update.

I only noticed some screen flickering when I use the panorama function of the camera app. I've also seen a youtube where a guy is complaining about screen flickering. But this is an older video and this use was using an older version at the time.
In case you didn't know, this rom comes with GooManager. You can use it to check for updates for this rom.

Standby screen flicker issue

I noticed on the battery drain thread a few people have described this issue where the screen flicks on and off occasionly while in standby.
I have noticed this myself many a time on the occasional chance that i glance over to my phone and see the screen flick on and off. I was hoping it would just dissapear but still happening. I guess this deserves its own thread to find the cause?
Obviously its hard to pinpoint what does it, so far my gut feeling is telling me it only flicks on and off when wifi is enabled? Dont think ive noticed it while on 3g only.
i have this flickering too ,even when wifi is disabled.
I have had this issue too & it gets very annoying during the night
I have tried disabling 3g,WiFi,auto brightness,pocket mode but it didn't help
i am currently on stock ROM ,do the people using custom ROM also face this problem?
Yea im using coredroid, i imagine its a nasty battery drainer too

Same here.. Went to the htc service,told them about it, they scratched their heads and said that they could send it to waranty but if all you guys are facing the same problem i guessed i shouldn't bother because the new one is goig to do the same..
Also, excuse the off topic, but anyone having problems with the "locations" maps. Mine fails to start. I mean, it starts then exits in about 2 secs..
I've read abut this problem in other threads on this forum but over the last few months have never experienced this problem On my own device
I've not encountered this issue on either my base stock rom or on any of LBC ROM version which I've run for the last month

when you're sure it'll happen at least once within time x, i would install eclipse + adb-drivers, hook up the phone, and then have a look at the dmesg/logcat log as soon as the display turns on...
might be worth a try to finde the reason for this behavior, which i luckily don't experience...
The odd thing I find is that only some people get this, perhaps people who suffer from this should post their country of purchase, rom and radio version so we can attempt to identify if this is related by something in common
I'd also suggest that people who suffer from this also try factory resets and try running stock without any applications so that we can see if this is caused by a particular application or is indeed rom our device related

Yeah, you're right.
last night when I was playing with my friends, I took a glance on my phone, it's just a bling bling bling occasionally. I don't know why.
I'd closed wifi but 3g was on.
Haven't experienced this but I'm pretty sure it's a kernel problem for the wake-ups. I saw in the battery use menu some tiny blue bars while the screen was off -> wake-ups.
If we can catch it on a log and report it to a dev, I'm sure he could fix this.

Did you try my advice above,
Which unfortunately involves resetting and running stock for a bit to see if the problem still occurs?

@bongo1 i also face the problem only at night
can you tell me your radio,hboot,kernal version & the roms you have tried?
@ben_pyett the problem happens only during night & when my room is dark & it doesnt happen in a regular interval so it maybe difficult to spot,can you try staring at the device for 2 mins or so in a dark room once more for me? just so that i can confirm
& i tried factory reset ...& i am on stock rom ,cant try others as i am s-on
Im running Core Droid latest V1.1, rom is probably irrelevent as i have noticed it on other roms too.

I would tend to follow your idea that it only happens in dim lit circumstances, i have particuarly noticed it in a dim lit room however its possible we only notice it because its more noticable in a dim lit room.... will investigate further tonight.
How would i go about abd debugging this? im not realy sure how to start.
I'm reasonably sure that my device doesn't have this problem, as every night since I've owned it (about three months now) I've sleep with the phone on the table next to my bed as it's also my alarm clock (about 12inches from my head).

i suspect the same thing
the only common thing we have is the radio rom & the hboot ,i doubt the hboot has anything to do with this...
can you try changing the radio if possible? i am unable to as i am s-on
im not sure how to use adb myself as i am still a noob
but try reading these guides (not sure if they are what you are looking for)

So I'm not crazy... Noticed this once at night. But it was so short and the display brightness was so low that i wasn't sure if it was only the reflection of the light outside.
I'll try to hang it up with logcat tonight. I also noticed that the phone wakes up even if the display isn't active at least 20 times last night. Though it didn't hurt the battery that much.. This is annoying me.
Okay. Tried just about everything there is to try (except for radio image flash), still no solution..
The issue persists with stock rom, s-on, s-off, rooted, unrooted, lbc rom, virtuous rom, etc.. It flickers all the time, at about 2-5 min intervals, more noticeable at night (well due to the absence of light i guess). Wondering if i should send it to service as still in waranty.. The problem is that i do not mind the screen flicker but the battery drain associated to this. Let me explain how bad this is.. I disabled everything: backgroud data, wifi, mobile network, screen backlight to minimum, sync, pulled out sim and sd card, fully charged and went to bed. After about 8 hrs of sleep when i woke up phone battery was at 76%. Do the maths and that's 24% battery leakage due to just android os, sense stuff and this stupid flicker.. As i'm seeing this is not a common issue as this thread is not flooded with replies. In a dilemma right now as i really want this fixed but i'm kinda' reluctant to send it to waranty as the other aspects of the phone are brilliant and don't want to end up with a refurbished replacement phone or with the other problems associated to the DS (screen edge backlight bleeding, squeeky casing, poorly mounted display).
My specs right now are:

[Q] screen issue....maybe?

I got my charge as a replacement for my fascinate like many others. befor i do anything i wanted to give the phone a few days on stock to make sure everything works fine. So far the only thing i noticed was sometimes it lags when i hit the power button to turn the screen on. Sometimes it flashes a static filled screen for a split sec before home screen loads. also some times it takes a sec for my screen to come back on after i lower the phone from my face so i can hang up. Is this just a little minor known issue others are having or is there something wrong with my phone possibly? Phone is all stock, fully bloated and the only apps ive installed are xbox live stats and google googles (coolest app ever). I doesnt do it all the time but it happens frequently enough to notice it. I can normally recreate it if i hit power button to turn screen off and let it sit a few mins then hit the button again to turn it back on.
When running completely stock, I experienced the same 2-3 second delay. Now that I am on EE4 with a custom kernel, the delay is closer to 1 second.

did you ever see black/white lines or static? I only ask because if its a common thing that most have exp then its really no big deal. ill root and flash to help fix the lag. But if its not then i would like to get it fix asap. Other then that i havent seen any other issues yet.
I see the lines and"static" on mine when the screen comes on. Not every time though.

I have seen it on occasion. It's much less noticable on a custom kernel and ROM.

Thanks for posting everybody. It seams like its a common issue then. I just wanted to make sure it wasn't just mine or that i needed to return it due to some kinda of defect. Nice to know a custom kernel will fix it for the most part. Thanks again guys. This phone is so much nicer then the fascinate
I set a lock pattern on my phone, and I haven't seen the screen flicker once since. I'll switch back to the puzzle lock and see if it comes back....standby.
*update* switched back and still no flicker. Maybe that's the ticket.

I have it on two replacement phones I got through amazon . White lines for a split second .

Screen randomly turns black?

For the past two weeks or so my Sensation 4G has been acting strange. The screen randomly goes black and the only way I can get it working again is to pull the battery. Whats odd is that when the screen is black all the buttons at the bottom are still lit up, and when I touch them the phone vibrates just as it does usually. It seems as if the backlight has just turned itself off and doesnt want to come back on! Has this happened to anyone else, and if so, what is the remedy?
Do you have a custom ROM? ARHD had this issue

Nope, its as stock as the day I bought it from Tmobile.
Not happened here, but it is an issue that has popped up on the evo 3d. In fact phandroid just ran an article about it. Most people with the problem seem to be 100% stock.
The odd thing is that it only just started happening and I have had the phone for a while.
Happened to me too a few times. Gotta pull the battery everytime. I'm not sure what's the cause of it
Try a factory reset, and if that doesnt work, take it in, and get a replacement.
Its just irritating (and infrequent) at this time, so I am not sure I want to return it yet. If it becomes any more frequent I will certainly send it back however. I am thinking of getting a replacement anyway given that I also have the infamous dust under the screen issue.

are you running custom roms?
Got the same problem and i know one other Person who does. Problem stopped appearing for some time and now its back worse than ever with random shutdowns even during calls. Running Stock HTC ROM not rooted or anything. Found some clues on the internet that it might be caused by a SW Update that came from HTC. Nothing for sure though. All i know is that i am seriously looking for another device at the moment. HTC and Android devices are annoying me more and more lately. No Official Updates (or they take 6 months), Compatibility Issues... The list grows longer every day. I used to love Android Phones, especially the HTC Ones but they appear to be stuck.

you have just been unlucky...i'm running custom roms and sometimes i get random reboot but now it is all ok!
send it back!
I had exactly this problem, phone kept turning off at random. Mine was totally stock, first time I sent it back they re-flashed but it started turning off again after about 2 weeks. I sent it back again, they changed the motherboard and its been working fine since then (touch wood!).
Also had random shutdowns. Got a new battery and the problem was gone. But now 4 months in on the new battery same thing starts to happen again. Beginning to thinks there's something wrong with the power management.
Sent from my HTC Sensation XE with Beats Audio using XDA
there is actually an issue on the power management, which is fixed with the ics update. If you can wait , you'll get an update from htc
if you cant, go ahead and flash a custom ics rom
I had the same problem before I bought a new battery and i hope it wont come back when the battery gets older. The problem was with 2G networks. If you turn the mobile network to WCDMA (3/4G) only in the settings, the phone shouldn't shut down. I hope the ICS update completely solves this
Sent from my HTC Sensation Z710e using XDA
I had the same problem as well. I flashed ICS and it would still shut off. I noticed it wouldn't ever shut off if it was just sitting on my desk except one time it shut off when on my desk and someone called and my phone vibrated. Turns out the battery connection wasn't tight enough and when moved around, it would lose power. I folded a small piece of paper to make the battery fit tighter and it hasn't shut off since (about a month)
Hi all, I have gone through this problem... I have done all troubleshootings S-off S-On different roms new sim car everything even flashed by service station not helped...on solution for random shut down for me was changing motherboard and after they changed my motherboard I haven't faced single issue... get board changed.
Issues
1) random shutdown
2)while calling some shuts down
3)If it shuts down it will again shut down imd. on 2-3 attempts then start properly.
4) when screen is off and u push power button u find phone down
5) Random shut down some time imd or it will not happen for for next 8-9 hrs.
Get mother board changed.
I was experecing the same issue.
Random reboots or random shut down !
Never when my phone is charging, only when it is on battery.
But I'm trying something, the auto brigthness ! I desactivate auto brigthness, for the moment no ramdon reboots or shut down anymore, was testing 2 days now ! Perhaps try this solution !
Sent from my HTC Sensation XE with Beats Audio using XDA
Try to remove micro sd card,test the phone and if it does work ok change the card,that was my solution.
3 users in my office are seeing this
3 sensation users in my office are seeing this too, the UE "powers up" when you attempt to wake the screen i'm taking logcat but i'm yet to determine if the phone is powering off at some time when the screen is off or when you attempt to wake it.
i am seeing the battery stats are all over the place after it boots up.
this does not happen when it is being charged.
the logcat from my phone sometimes say a process has crashed (latest 03-06 17:06:18.995 I/ActivityManager( 321): Process com.htc.ereader.drmengine (pid 2742) has died.) but not in the majority of my logs they just appear to stop,
if anyone is proficient at logcat analysis i can share a log taken of a failure.
the 3 users in my office have:
1X S off and ICS ARHD
1X S off and ICS (trips)
1X S off GB unbranded
any help would be gratefully received
**EDIT**
having just pressed the power button to wake the screen(19:00) the phone booted again i was able to check the logcat log file and it stopped logging at 18:02 so it appears to be crashing when going into sleep or when in sleep mode rather than when the wake command is issued
also: http://forum.xda-developers.com/showthread.php?t=1500966 looks like the same issue.
Same problem on HTC Sensation with ICS
Hi,
Sorry to crush your hopes for ICS solving the problem but I'm running Android Revolution 6.5.0, a custom ICS ROM, on my Sensation and I'm having the same problem. Never had it with the stock ROM, though.
Also, it's never happened when plugged-in or when the battery is full. Seems to me that it shuts down more frequently when the battery level gets lower.
Anyone experience it the same way?
Anyone solved the problem by replacing the battery?
Cheers,
Stefan
Hi
any news about this?. Is this problem caused by a hardware failure finally?
Thank you!.

Well I got my battery replaced. Worked fine for about 3 months. Now the issue is back. I think it has something to do with the power management on the phone wearing down the battery. When I plug in my charger I feel electricity in the back cover and a humming sound in my headphones. Somethings wrong with the hardware. Going to send my phone in now

I get a weird humming feeling too, like a vibration as you run your finger over the back. Whats also weird is that if im holding the phone and then someone runs their finger on my hand, they also feel the static/vibration feeling. However as soon as I put the phone down the vibration feeling goes. Its so weird, if I send the phone off I'll be phoneless for weeks!
Very simple solution
Hi guys,
Most of us (myself included) are sometimes blinded by our knowledge of custom roms to not try the most obvious fix for this finally very simple issue...
I have a park of about 20 HTC sensation on my company and had the problem on several of them (mine is running a CM9 nightly , but all the others are stock). Had the motherboard/battery replaced on some of them, tried many settings (and on my phone, different roms) but it only offered a temporary and random improvement. I found the solution on a forum and I'm ashamed I never found it earlyer as it's so simple:
Remove your back cover and place a spacer (the thickness of one or two visit cards) between the top side (right part, just opposite to the connector) border of the battery and the chassis. This will ensure that the battery presses a bit harder on the connector. Without the spacer, you may notice that the battery is in a slightly skewed position, not totally parallel with the compartiment and therefore not pressing hard enough on the connector. We never had an unexpected shutdown since then !!!

Touch Screen Issue tf101

I have touch screen issues and I'm not sure if it is Hardware related or software.
I will be using my tablet and all of a sudden I lose 90% of control. Basically, I can't touch anything. I know most would say that hardware but, I cycle the power button (Not turning tablet off just screen off screen on) and touch comes back.
I noticed this issues when ICS just came out for our tablets and we were getting major RR and SOD.
Any one else experienced this or am I the only crazy person that this happen to.
Thanks in advance.
Ps. If you have experienced this please post solution.

It sounds like you may be on a different ROM then stock. I would recommend a couple of things. First back your system up, and do a clean install. Clear all cache and go. If your on a non stock ROM, then It would probably be a good idea to visit the thread of that ROM and see what they have had come up about the issue.

That is correct I am on Non- stock rom. Guess I should have said that. Should i go all the way back to original rom (HC) then up grade to ICS(stock)?
I have tried multiple custom roms but they all seem to do the same thing. Me being a comp. tech. the way I can restore touch by power cycling makes me think it is software.

From you response, this is why I am thinking this is related to software. I do not have the proper knowledge to research but I am asking help from a knowledgeable person.
I screen losses touch regularly now. it is taking away from my experience. Are there any drivers particularly for the screen input that can be updated or downgraded to a known working version.
Thanks for not making me fell like I am the only crazy person!
