Strange things happened to my Galaxy Tab Wifi version - Galaxy Tab Q&A, Help & Troubleshooting

Yesterday, I briefly pressed the power button and kept my tab in a zip case for half a day; and when I pulled it out, the case was so warm, and I can't switch on. So I have to switched it off and on again. The reason why it was so warm inside the zip case was the GPS was still on and working at all time.
The strange things after switching it on are:
1. my unlock pattern has gone
2. the usb mass storage setting reverts to Kies
3. pressing Home and Search button do nothing
4. SmartKeyboardPro default reverts to Samsung keyboard default.
Last night I tried switch on and off several times, and it did not solve the above problem.
This morning when I plug my USB cable and notice that it asks for Kies drivers, I then set it back to USB mass storage and re-plug my usb cable again. Suddenly, the Home and Search buttons are now working again.
I have to set the unlock pattern and set the Smart keyboard pro as default again.
Now my Galaxy Tab wifi version works as normal again, but I still don't know what has caused the above problem.

why does the h6515 power itself on?

question, i've got a 6515 and it keeps powering itself on. when i turn it off (with the on switch), it automatically powers on after a few minutes. this drains my battery within 18 hours since the pda function is activated (back light and screen comes on). it keeps powering on automatically every time i turn it off. i disabled all connectivity (no sim present, bluetooth of. so both are disabled). i disabled the gps download applet, so it cannot automatically download. i disabled the active sync setting (After setting it to manually and unchecked all the peaktime settings). i also tried to reflash my current rom (the latest), but it keeps powering on? i also took out all the memory cards and there are no third party applications installed (just did a hard reset). any help is appreciated, or else i will throw the thing out of the window (then i know for sure it will never turn on again)!
mine did the same thing for a while and it was related to activesync and blutooth ativesync. no idea what fixed it tho. sorry
Disable Hardware Buttons
Have you tried to disable the hardware buttons to see if it maybe a button that is getting pressed. To disable them hit Start, goto Settings, tap Buttons, tap the Lock tab, then put a check in the "Disable all buttons except power button" box.

Powering X1i through USB -- any hacks to do the following...

Hi all,
I frequently charge my X1i through USB. There are 2 problems with this method, however.
1) The device goes into USB drive mode, disabling my SD card apps (I keep them on SD card AT ALL TIMES due to frequent backups/restores)
2) Screen does not turn off! while connected to computer! The screen only dims, but does not turn off.
WITHOUT resorting to a) plugging into wall outlet b) connecting to Activesync, is there any to fix these behaviors?
Thanks!
just let it go into activesync mode, that way you can still access your files on your phone and micro sd card from both your pc and phone. And if you dont like the screen not turning off, they just change the settings or just press the power button, to shut off the display.
I know about the power setting, but when your computer is connected to the computer via USB, it refuses to turn off the screen (only dims it)
what? one simple button press and the screen is off. the device is still visible to the pc. I do it all the time - r3a generic uk rom.
in power options u can set after what time it disables screen... default is never

Weird. When I'm connected to Pc, it dims the screen, it does not shut it off. Also, it does NOT auto-shut of screen after the 2 minutes specific in the Power options
You can also use "safely remove devices" to disconnect the data connection from the phone, it'll still charge.
There's nothing we can do AUTO. But like said before, a simple pression on the power button will do it, or you can use My Mobiler and press F11 on your PC.

Yep, I've had 5 different WinMo devices since '05 and they all worked as expected except the X1. I like to use it as an MP3 player at night, Pocket Player has a sleep timer built in so I just like to leave it running as I drift off most nights. But if I do anything, change the volume, rewind, anything at all the screen comes back on and stays on until I hit some other button to turn it back off. All my other devices obeyed the settings you set in the Power tab, but not the X1...
I'd very much like the screen to auto-off if I tell it to while on USB power. It's not only wasting power, but it wakes me up and gets me fumbling for the tiny power button at 2 in the morning. Any fix would be greatly appreciated.
Thanks,
Peter
I bumped up thread: http://forum.xda-developers.com/showthread.php?t=561832 Since it has a better title and shows the exact same unresolved issue...
Reg Fix
Adding this potential fix here as well so anyone subscribed to this thread sees it.
Ok, I think I have a fix for this. I googled around some more and found that this might be an HTC problem more than an SE one. There were various registry keys people suggested to try to fix the 'backlight problem' - which may or may not be related. None of those suggestions seemed to work, but I kept changing keys myself and eventually found this seemed to do the trick.
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power\Timeouts\ACUserIdle: 120
I confirmed that changing this value affects the amount of time before my X1's screen turns off - but my MP3s still play with the screen off and my phone wakes on receipt of a new call. This value is the # of seconds before the screen turns itself off (in this case 2 minutes). You do need to soft reset for the change to take effect.
This doesn't seem to be posted anywhere else that I've found doing this to fix this issue issue - I changed a few other registry keys as well that might be enabling this fix. So anyone with this problem, please do give this a try and if it doesn't work I'll post the other keys I changed as well - and if it does then post to say so and we're good

Update: I tested it also while hooked up to the computer and it does work with the phone accessible through active sync with the screen off and the battery charging (faster now that it isn't competing with the screen for power, except for the 2 minutes before it times out). If I want to use it I just click a button and the screen stays on till I leave it alone for 2 mins and it remains off. Get a call or a message and the screen goes on for 2 minutes and then off - Exact same behaviour on AC and USB - exactly the behaviour I wanted .

[Q] HELP! SGS doing funny things - USB connected

Really need help guys. My SGS is doing REALLY funny things...
I just got my SGS a few days ago and so far all I've been doing is installing aps on it (no messing with rooting/flashing).
Today, I was trying to get Keis to work. I reinstalled Keis and unplugged and repluggeed my phone a few times and managed to get it to recognise.
Here's the problem, now it ALWAYS says USB connected on the top left hand corner. Everything seems ok except after a few minutes of the screen turning off, I can't turn it back on again. Absolutely no activity. If I try to turn it back on immediately after it goes off, it can come back on again.
Things get weirder. If I remove my battery or turn it off, I can't turn it back on again (it flashes a loading symbol in the middle of the screen for half a second then nothing happens). To turn it back on, I have to plug it in and wait for the charging screen to come on. THEN it comes on.
I've tried doing a factory reset but nothing changed... Is there a hardware fault? Perhaps flashing will solve the problem?
ps. When it's off, I can enter download mode but not recovery more unless I plug it in...
Sounds like a hardware problem on phone, But I beleive its more of a Grounding problem with your usb. Can you try it with another port or computer? Also does your pc/laptop have a grounding pin for its power supply? I noticed I get odd power spikes when I travel to asia as their power is not always good. You can always buy a surge protector for your computer and one for your samsung charger. Other then that see if you can get new KIEs (I Don't EVER use it as its crap and never reconizes my phone)
Also if you want to kick up a storm, get the thing replaced as it sounds like a phone hardware problem as it should not crash when you take battery out. Could be battery but better to change the whole thing.
Try activating USB DEBUG in settings. Check the option and restart.
It should solve the problem. You can UNCHECK again the option and the phone should work also without USB debug activated
It will happen again, it seem to me a problem with some USB port, or some cables, activating a *waiting for USB* option BEFORE the ROM loading
Thanks
Thanks for the advice guys. Last night it suddenly started behaving itself after the 10th or so hard reset *phew*
Very strange problem and I think I will stay well clear of Kies from now on... Samsung make a good phone but lousy software...

[Q] Startup and device driver problems preventing me from upgrading/rooting P1010

I decided to try and upgrade my galaxy tab 1010 to Gingerbread in the hopes that it would fix a problem which is that whenever I click on the power button to open my tablet (not to turn it on but just to resume from sleep or whatever), the screen lights up black and the bottom lights are on but it takes countless retries to get the thing to actually appear or it just stays black. Even a restart is not enough at times. This is causing me problems with updating because to make a CWM backup for example, it has to boot into the menu which I can no longer see after it shuts off. Sometimes it works fine, other times I give up trying to get the main screen to show up. I can click on the buttons at the bottom and get the vibration feedback and can also hear the audio going up/down when I click the volume buttons but often the screen will stay black.
The 2nd problem is that although I have Kies installed, every time I connect my device to my laptop (Windows 7), the laptop will install drivers for it separately. This is a problem because in Odin for example when I try to flash CWM on to there, after I've flashed it, it will turn off in order to reboot meaning that it disconnects from the laptop and when it boots back up, the laptop does not recognize. So to fix that 2nd problem, I need a way to install drivers on there so that my laptop always recognizes it rather than installing every time.
Thanks for any help....the black screen thing is really frustrating me and I've done some searches where others have black screen problems but their are usually different and the device won't come on at all in those cases rather than come on sometimes and not come on other times unless I try several times.
Good news is that I managed to upgrade to gingerbread with the root and it was working...Odin did the trick though still can't get anything going on Superoneclick on my Galaxy Player because it's not recognized when in USB debugging mode. Upgrading did fix the problem of the screen not coming on and staying black.
Bad news....installed bloatware removal tool, removed a few apps which I was sure were non-essentials (Samsung movie guide, visit Britain, couple more like that)....and it seems to have hard bricked. I found this tutorial on hard-unbricking but it's for the p1000, dunno if it would apply to the p1010: http://forum.xda-developers.com/showthread.php?t=1312391
So gonna either try that or since this thing isn't under warranty anymore, I have to find somewhere in Mississauga Canada which will do a hard unbrick on this.

s6 went mono

A strange occurrence happened yesterday with my Galaxy s6 from T-mobile. It is stock, unrooted, and on latest release. all of a sudden, the display screen went into monochrome (black and white ) mode. Battery was at 44%, so i dont think it was due to power saving. I also connected charger to further charge it. After some minutes, i turned it off, and restarted. While restarting, i can see samsung logo in color, and lockscreen was in color for few seconds, and then display immediately went mono. after few couple of more reboots, i wiped the cache in hope to clear any issue due to any app update. but still the same result. Then switched from Nova launcher to Touchwiz , but still the same even after one more reboot. So, i thought the phone may have become defective. Then , after a while, just pressed home button few times trying to unlock the phone, and this time, the screen came back to color!!!!
Has any one ever experienced this? What could be the cause? Software or Hardware?
ok, finally figured out what happened. There is a "Accessibility" menu, and one of the "direct access" shortcut is to make the screen grayscale, for whatever reason, that shoutcut key was checked. once you press home key 3 times in succession , that feature will be enabled.
