Vibrant Freezes and WIFI freezes?

So I've had the vibrant freeze on me about 3 or 4 times out of the 2-3 weeks I've had it so far. It's gone black with the bottom four buttons still lit but it wouldn't shut of via the power button or respond to any other buttons either. Also, one time it froze yesterday after I did a master reset through the factory reset option. This time it froze while I was trying to do a speed test, the screen stayed on in the speed test window but buttons were once again nonresponsive. I haven't replicated it yet though. I have to pull the battery to get it restarted.
Another issue I've experienced a couple of times is the wifi would freeze when I turn it off through the power widget (my normal method of toggling wifi). It says that wifi is turning off but it stays in that state and never actually does. The green light would dim on the power widget as though it's turning off but it sticks there and under wifi info it just says it's turning off. When this happen, wifi will neither turn on nor off and just becomes unresponsive. I have to restart the vibrant to get wifi back to normal.
Anyone else experienced this or have any ideas on these problems?

has any solution been found for this ?? i have similar freezing issues with my vibrant .. i found one possible culprit listed on another site .. there is a way to disable the TeleNavGPS app (as you cannot uninstall) .. it is supposed that this interferes with the phone to the point of complete failure
Are you running stock 2.2 from Kies? I had exactly the same problems.

You could try backing up and doing an ODIN flash to KA6. I've had similar lockups with some builds in the past but they are fairly infrequent. Currently running stock KB1 rooted with KA6 radio and it has been smooth for a long while now.
I've tried some of the 2.2.1 Roms, but I absolutely need wifi calling so I stick with stock.

I have the same issue. On my second Vibrant running stock 2.2. About to send this one back for warranty as well. Mine will freeze from the lock screen, either stuck on the screen and the display stays on, or the screen wont come back on from idle.

Have you tried another ROM? I thought my phone was broken with stock 2.2. Haven't had issues with Bionix.

No other ROMs, I know there are a lot of good ones, but I shouldn't have to root my phone for it to work correctly. Within a week of this current Vibrant I was having these issues. I didn't purchase the Vibrant to flash ROMs, I bought it because of the specs to remain stock. On a side note..I was told after 3 warranty replacements within 90 days I will be able to get another phone from them.

Yeah, know what you mean. It is silly that stock is just broken. Hopefully the OTA will be better than the Kies release. (Are they doing an OTA?)
Maybe they'll swap for a Nexus S.

im rooted on android 2.2 but stock rom stock modem stock everything just root. i have had the same wif issue as the op. i just go to settings>wireless settings> wifsettings and turn on wifi that way. if you notice it will say error. 90% of the time this works and you will not have to reboot. i switch from wifi to 3g a lot. i have not figured the cause just yet but this is a work around for now.
as far as deleting the bloatware i rooted and deleted all that crap like sims, and other apps that i do not/will not ever use. there is a thread on which ones are safe to delete. be careful about deleting apps that are used by google such as google talk.
Unreal, Samsung. I wanted to sell my Vibrant, but can't get anywhere near what it's worth because of these stupid issues.

I'm having the same problems!!!
I am now on the 3rd replacement (that's the 4th T-Mobile's Samsung Vibrant 3G!!!) and still having problems.
My phone will just be sitting on my desk at work and I'll hear it buzz a couple times. I know that buzz. It's something "Force Closing" in the background. I will pick my phone up and it will be unresponsive. It will light up the 4 buttons on the bottom of the device, but nothing else. Normally, it will then immediately start rebooting. It will go through the usual start-up screens. It will then show the status bar at the top; battery life, alarm clock, signal, 3G/WiFi, Media Scanning progress. However, the rest of the screen will be black. It will then vibrate once, then 2 more times and do it all over. It repeats this at least once for around an hour EVERY DAY!!! Other times, it will not restart on it's own and I will have to hold down the power button to manually do so.
I have also gone through ALL the troubleshooting I can imagine. All logs, history, texts, cache... EVERYTHING... has been cleared.
Please forgive me for asking, but it appears that I am to possibly root my phone for a resolution... is this true?
Also, has anyone heard of this "3 Returns Within 90 Days" policy with T-Mobile? I could easily do this with this phone. Has anyone had any luck getting them to do that?

Screen keeps turning on and off by itself

Hi guys,
I've been using my Optimus 7 for barely a week now and I ran into this very annoying issue I've just discovered yesterday.
Every time i turn off the screen, it would turn itself back on(showing the lock screen), few seconds later the screen goes off, and then on again. It doesn't happen to me when I am using the phone, so it can't be the power button's fault. Restarting the phone does not help either.
My phone is unlocked with Chevron 7.
Anyone have any solutions?
Thanks in advance.
Having the same problem after 3 years of none. I have not downloaded anything in that 3 years as well as this is just used as a phone ( data is too expensive in rural Canada ). This only happens when the phone is not being used, when charging no problems, only when on battery does it do this, I guess no answer is coming if the original author had no answers for opver 4 years but any suggestions would be great.
Thanks all.

Phone application screen freeze with android ROM"s

Hi this is my first post on the forum.I"ve searched for similar issues,but I didn"t find anything.I bought a HD2 last month and installed various android ROM"s,everything fine since last week.Now my HD2 have this issue:
-I make a phone call and after 2 seconds the screen goes black and freeze.If I want to activate the loud speaker I can"t because screen is black and not responding.I can have the conversation,I can close the conversation from power button,but screen remains black and non responsive.When I close a conversation the phone remains nonresponsive for 5-10 minutes,and after that everything goes to normal.
-I have this issue since last week,until then every android rom that I"ve installed worked just fine.
Now I have on phone HD2_Core_Droid_Desire_HD_V1.5_Release_Version
and I"m having this problem with every Rom that I"ve installed since last week
I start thinking that it"s a harware problem,I don"t know...
Is anybody else who experience this problem?
Thank you very much,and excuse my poor english.I"m a Romanian living in Spain
Nobody have this problem or a fix?I"ve tryed everything with different radios and ROMs...
strange. i don't have that problem.
I"ve just installed official vodafone WM 6.5 ROM for spain and I have "almost" the same issue:
-during call screen goes black and no way to open it.
-the difference is that when I hang up screen goes on instantly and no freeze.
What is that,hardware malfunction?
sounds like a hardware issue
I hope not...
I"ve noticed that if I enable the loud speaker in the first 2 seconds(before screen goes black),the phone is not freezing,and no black screen,everything just work fine as it should.
I"m out of ideas...
Edit:I am now on [CWR-CLEAN] BOYPPC-SHIFTPDA GINGER HoneyComB V11 (30.Mar).
I see some people on this forum that have the same problem too.Nobody have a solution still?
Try an app from the Android market called 'Call Light'. It's supposed to keep your screen lit up at all times during calls, but what it has done for me is that when in a call, the screen still goes black when the phone is to my ear, but as soon as I take the phone away from my head, the screen lights up again instantly.
I had almost the same probkem as you do before using this app, except that as soon as the call was over, everything was back to normal (didn't stay black for the 5-10 mins after calls) now all is ok for me.
It might not work for you, but it's definitely worth a shot.

Yeah,I"ve already do that but not works for me.Sometimes (few times),phone app run just fine but many times I got that annoyng black screen.To get back to normal I have to do a reboot or to make a call from another phone to my hd2,then screen comes back.I don"t have this issue with incoming calls,only with outgoing calls(when I call somebody).When I make a call I have to activate loud speaker in the first 2 seconds to evitate black screen issue,in that way screen stays on during call and after I hang up I have no freeze problem.
I have "call light" installed,unchecked proximyty sensor in menu and checkedd the option that makes the screen stay on longer during conversation.
I am on BOYPPC-SHIFTPDA DESIRE HD GLass A2SD V12 (23.Apr)
kernel GL_V11
Radio 2.15.50.14
I am flashing the ROMs with CWR zip method always with ROM proper recovery.
HELP...... Stilll cannot use my HD2
BUMP........
Is this problem got solved yet?
Note that if you plug your cable to pc the phone will unfreez and will be laggy for secounds, did you try to change your SD card?
Solution
Everything difficult-is easier)
Just clean dust on the sreen,where sensor is situated.
ANd choose a ROM with Tytungs kernel 12.4v3 (with solved libsound issue) or a SENSE based ROM

black screen after possible graphics issue

hmm just had a really wierd problem with my telstra branded 4G LTE I9505
i was playing a game and it seemed to freeze and the graphics started getting really bright and pixelated almost yellowish. almost like artifacting like with a modern PC game when graphics card overheats.
it let me open task manager but froze and started doing the bright thing again and was almost going white and pixelated. i took out the battery to reset as it was frozen.
now i boot it up and have a black screen but the phone seems to be functioning 100%. I still get the S4 logo come up etc, it gets to the menu because i can hear the sounds for notifications etc still. connecting to PC it still comes up fine, all buttons seem to work as i can hear them doing things.
very odd, is my screen dead? it would seem its not if the logo shows up still? it just gives the S4 logo but not the telstra logo after it that normally comes up.
any suggestions?
i've tried removing battery, sim, sd card and leaving out for a while.
just worried as i have it insured but i only rooted it about a week ago with easy root. It still has stock rom i just dont want it to affect my chance of claiming it on warranty/insurance. and since i can't see the screen i can't unroot it. grr.
any help would be appreciated.
forgot to add, 2 days ago i installed xposed framework and Xprivacy could these have somehow caused it?

Galaxy Note 4 just went high

So, I know this phone is old asf but I can't find any tutorial and I really don't want to flash my phone for the 30th time again.
I just tried installing LastPass Authenticator (for 2FA), and when I launched it my phone just turned off, I tried booting it up and it went past the splash screen to the T-Mobile logo, and after that just shut off.
Now it'll just stay on the Splash screen for a bit, it won't even get to the "Samsung" animation, and just shuts off. It was stock ROM as well as stock recovery as well.
Don't know why this is happening, but its the second time something similar has happened. I really don't want to reset the phone due to the data I have on here, so any help is appreciated.
