The screen blinks - 7" Kindle Fire HD Q&A, Help & Troubleshooting

This is my first post around here, so first of all I guess I must say hi to everybody
Two weeks ago I bought a brand new KFHD 7''. I rooted it and followed the steps in order to get all the gapps correctly running. Everything worked out and the tablet performs great. But there's something that is starting to annoy me.
Initially I didn't care about it but now it keeps catching my attention and gradually bothering me more and more.
When I'm running an application and press the home button to go back to the Desktop the whole screen blinks twice. Moreover, when I recieve an email, the notification bar starts blinking as well and also hides, which turns out to be impossible to scroll it down in order to check the notification. It's getting desperating.
At a very first moment I figured it was an issue with the launcher (EX launcher HD), but afterwards, once I'd changed it to ADW launcher the problem persisted.
So what do you suggest me to do? Any tips or advice? Should I try to install kinology?
Thanks in advance and thanks for having this great phorum.

[Q] Woke up to a less functional Captivate..

Long time lurker, first time poster.
I woke up today to see my captivate screen showing blank screen (active black screen with buttons lighted up) being unresponsive. It was on it's charger from the night.
I pulled the battery to shut it down. It rebooted. I thought nothing about it until I tried to use it about an hour later.
I have had it on stock Froyo, with no root. Never have flashed any other ROM besides updates through kies.
Problems and things I've noticed so far:
No puzzle lock screen. Can't find it under "set screen lock". Only None, Pattern, PIN, Password available.
Home button and search button do not function(they light up like they are pressed, but not action occurs in any apps or home screen).
No data. Usually i'd see edge or 3g, but I have no data connection.
Text messages wiped. None available through "Messages"(though call log shows history of messages).
Keyboard was on stock android rather than swype(since changed back to swype).
Holding power button only shows "Power off" option. Before there was at least Airplane mode.
GPS was on(I hardly ever use it).
Location settings seemed to be default("use wireless networks" was unclicked)
Most other settings/app data seems fine.
About phone info:
Model Number: SAMSUNG-SGH-i897
Firmware version: 2.2
Baseband version: I897UCKB1
Kerner version: 2.6.32.9
Build number: FROYO.UCKB1

Other related things:
Day or two before I received a text message from AT&T to download Kies and use Froyo(Don't remember exact wording, lost the text message, but something to the effect it looked like a mass mailing text to update to Froyo using Kies). I was already on Froyo(flashed as soon as I found out it was available few months back).
I also got a text message about downloading their at&t app to manage my minutes and pay my bill(also already had that app).
My Captivate would randomly freeze/unresponsive a few times, but I didn't think much of it.
Google Music app seemed to randomly start playing the audio file i paused(just in my pocket, or once when i put headphones in to make a call).
Searching the forums, haven't found too much related.
One thread suggested using "home switcher", which I have tried(both Froyo and regular versions, though can't press home button for Froyo version). Neither seems to know what my default Home App is, but it only sees TwLaucher(I only have TouchWiz).
Tried installing an alternative launcher(ADW,LauncherPro), still no home/search button.
I'm without my computer for the weekend, so I can't backup my files and reset to factory just yet.
Anyone have any thoughts to fix this or know what may have went wrong?
I might finally make the jump to a Custom ROM if it'll fix this.
Yes, you should either flash a custom rom or do a factory reset. I will say an event similar to this, also involving text messaging, is what made me make the leap to Assonance, and then Serendipity, and I haven't looked back.

At the least, try a master reset.
You're not alone....
Two Saturdays ago, I woke up, grabbed my phone to see what time it was and my phone was going haywire. It as blinking, flickering and rebooted on its own a couple of times...without me touching it.
When I DID manage to access the phone after a reboot there was no connection. I couldn't call, send/receive texts, nor could I access most of the features (during one of the haywire moments, the phone popped open my "Gallery" folder and started running a slideshow and then shut down. Again, all without me touching it!) There was a distinct blue circle with a slash where the 3G bars used to be on the top right corner of the phone.
I did a factory reset and didn't help. Wiped everything off the phone, but the device was still going nuts.
I got the phone in mid-December and have absolutely pampered that thing. Never dropped, never scratched, never abused. So I was surprised when I took it into the AT&T replacement center that the lady told me that my battery was wet! Not the phone, but the battery. Those two white-that-turn-pink indicators are so close to each other on the phone that I can't see how one gets wet while the other doesn't.
So they give me a new phone. One thing I noticed right away was that my data usage went WAY UP with the new device. To put it in perspective, I used 100 mb of data in 29 days and 64mb IN ONE DAY with my new phone. I thought it may be a one-time fluke, but it's not. I am only 10 days into my new month and am already at 164mb out of 200mb in my plan. I have NEVER used 164 mb in the 6 months previous, let alone in 10 days.
Fun's not over yet. I noticed a lot of crashes and "Force Closes" with the new phone too. I didn't even have any apps downloaded yet and things were still crashing. Last night I pull my phone out to take a picture and...nope. Screen was all kinds of whacked out and it crashed. And still does now every time I open the camera function. I managed to get in camera mode fast enough to do a reset, but didn't work. The screen is fine otherwise. So looks like I'm back to A&T tomorrow for another round.
I'm glad you posted this, cause the same morning all this happened -- literally, within 10 mins of me waking up -- my computer (brand new - 2 days old) went berserk and shut off and my stereo started flipping channels, turning the volume, treble, bass up and down..BY ITSELF without me touching ANYTHING! It was pretty freaky. I wondered if I was struck by lightning the night before.http://media.xda-developers.com/images/smilies/eek.gif
I was finally able to get back home today and do a factory reset. This (somewhat) solved the problem. Everything is mostly back to normal(home button and search button work on home screen, lock screen is there).
Lost a couple of game saves as I had no method to pull a save file(was doing adb pull on some known file locations).
I did run adb logcat before resetting, and home button and search button seemed to trigger something, just not follow through(Search button did work in a card game as a forward button and home button worked in the kies app to exit, just never as a return to home button in apps).
I'll be looking to root and flash a custom ROM, especially root so I can do a proper backup in case anything like this happens again.
I just want to say thank you posting in q&a and doing research before and after your flashing started. Then searched after your problem. You're a new member of a breed that are few and far between. I will hit your thanks when I get on my computer, app doesn't have it. You will go far here.

[Q] BSOD/Homescreen hanging on boot

This started a couple weeks ago when my phone randomly rebooted and had a bsod on reboot. After trying everything I could find, I gave up and did a factory data reset. It brought my phone back to life, and all seemed well in the world. Since then I only installed a handful of programs, nothing new within the past week, and suddenly its back to the bsod on boot. I booted into safe mode and found the screen would stay on, and noticed everything looked normal except the lock and vibrate/speaker images were shifted vertically for some reason, but still no touch response. I tried calling it, and an error message popped up saying homescreen wasn't responding and gave me an option to FC or wait. I FCd, and it let me end the call, but no touch response after that. I tried booting again in normal mode, and tough it stopped updating the screen at the droid eye, when I called sure enough it pulled up the incoming call screen, behind a message that launcher pro wasnt responding. I FCd again and answered the call and it worked, but again no touch response made a difference after that.
I'm thinking at this point I just need another launcher I can install via recovery, be it stock or otherwise. Does anyone have a launcher I can install this way? Itd be a huge help. Thanks in advance!

[Q] Upgraded to ICS scrambled graphics on screen (GT-P7310)

Hi,
I received the 8.9 yesterday and was very happy with it. Played with it for an hour and went out for the day.
When I got back home I downloaded and installed Kies on Windows 7, plugged in the tablet and new ROM was detected. Installation was straight forward and no errors, booted up the tablet and ICS was installed no problem.
Logged in via my Google account and updates started etc. The problem is the screen, if the screen goes off and I wake up via the power button the screens graphics are scrambled, you cant read anything. Looks like a spectrum loading screen.
If I hold down the power button to restart the tablet the graphics load up fine, I can use it OK, no graphical problems. If it goes asleep the problem returns (everytime).
I know I did everything properly, no custom roms were installed, programs that were downloaded via play are also used on my S2.
Rang up the online store for a returns but somebody is getting back in contact which could take 48hrs!
Is there something I should of done/could do?
Many thanks,
Mike

[Q] Issue! HTC One Crashing

Hi guys, i am kinda new here, hope i am on the right spot.
I recently bought a HTC One in the Netherlands. Its a beautiful phone! Already like it more then my rooted Xperia Z.
Today (The first day) i started installing my phone. Setted up some random things, untill i came at the Google account set-up. I already had one, so i chose that option. Then the first crash occured. The phone sent me to the screen i started 1 minute ago, the "Select language" screen.
I ignored that, and choose to set that up on an other moment.
When I tried to open Facebook, it showed me the logo, the logo moved up, but then it crashed and closed the application.
1 minute later, i tried to pull down the notification bar, but then my whole phone crashed! It rebooted.
I tried to update the phone software, didnt work. I also tried to do a hard reset, didnt work either.
The summary:
I cant set up an existing Google account, it crashes.
I cant open facebook, it crashed.
Sometimes, when i pull down the notification bar, it crashes.
Can someone help me out?
Excuse me for my grammer/typo's.
Lots of love.
Richard.

If you can get past the setup screens, do a full reset of the phone. But it sounds to me like the phone may have a manufacturing problem and needs to be returned for an exchange.

Hey Richurdt.
I know you're HTC One's issue was long resolved already. I wanna know how you fixed your issue. Because I have a very similar issue to yours before. I'm afraid that mine might be a hardware problem. I used my HTC One for almost 4mos then I had the same issues as yours came up.
I hope mine doesn't need to be returned to the store.

Z3 Compact randomly black screen

Hi there
I have a really annoying problem, that happens maybe 3-4 times a week.
Take the example that just happened today, I'll be using my phone writing through messenger, and then suddenly the flow function doesn't work in swiftkey, but I could still write messages and get responses.
Then when I hit the home button my screen goes black: *Don't know how to link to pictures on a new profile*
I can still pull down the notification bar, and pressing the recent apps let me see the title for the last app I used for a split second before it goes dark again.
I can even open my camera app, through the physical button, and when I returned it looked like this: *Can't post pictures*
I can always fix it by restarting my phone twice, the first time it doesn't register the sim card, and after the second time everything is working and back to normal.
I've considered factory resetting my phone to see if that would work, but I've so many apps and settings customized, that it would take a very long time to restore, and even then I'm not even sure it will fix it.
Could it maybe a hardware issue?
It happened on 5.0.2 and still occur after the 5.1.1 update
I really need your help guys.
