I can't offer a solution but would be keen to see if anyone can. I have the same problem. My 7.7 3G just won't connect to Kies. I'm running Vista, but will soon have a new PC with Win 7, so will try again then.

No probs with my SG2

For Q3, found a slightly easier way via the "update.zip" method over at this thread : http://xdaforums.com/showthread.php?t=1458021

It's under Tab 7 Plus forum but I've tried it and it works for Tab 7.7 as well.
[Galaxy Tab 7.7 General] Theory:
This is good. The original poster noted that the method "won't work for a device that doesn't have CWM Recovery installed." What about your own 7.7: was it rooted and did you have CWM Recovery installed when you use the update.zip?
[Galaxy Tab 7.7 General] lowem:
Yes, my Tab 7.7 is rooted, using the root.zip method discussed here. And yes also to the second, I installed the CWM Recovery 5.0.2.7 discussed here.

What is the LOST.DIR folder?

Can the folder itself or the files within them be removed?

Is there a safe way to remove the tablet from the connection a computer via USB?
[Galaxy Tab 7.7 General] Theory:
Not sure.

I've always just pulled my USB cable out. Doesn't seem to be any issue. I suppose it's more proper to effect it on the PC first.
[Galaxy Tab 7.7 General] teiglin:
Windows doesn't have an "eject" or "safely remove hardware" option for devices connected via MTP--at least, not one like it does for HDDs, flash drives, or other USB mass storage devices. As long as you're not using the connection it's fine to just unplug it.
[Galaxy Tab 7.7 General] Theory:
Yep, I just doublechecked and there is no eject option. So I guess I wasn't being lazy all this while after all.

Checked around and it seems the LOST.dir contains file/fragments that were recovered during file system check at each startup. It should be ok to delete the files in the LOST.dir.
[Galaxy Tab 7.7 General] uncle_buckman:
Cheers,

I have just tried to copy a avi file over to the SD Card and chose the 'Yes (Recommended)' option when converting the file. When it finished it couldn't play!

Why?

I also pluged the device in once and the SD card memory read 128MB?! What the hell is going on?
[Galaxy Tab 7.7 General] teiglin:
You don't want to have Windows do any conversion--always choose the option that just copies the file--for copying a single file, the dialog option reads something like "No, just copy the file (your device may not be able to play it)." I tried letting windows convert once, just to see what it did, and it spat out a wmv file with no actual video, only audio. Pretty fail. If you have issues transferring with mtp, you can still use adb to transfer files over a USB cable. If you're not comfortable with adb, people have suggested a number of good apps to transfer files over wifi without the need for a cable.

As for the size error, I have no idea. If it only happened once it's probably nothing to worry about.
[Galaxy Tab 7.7 General] uncle_buckman:
http://developer.android.com/guide/developing/tools/adb.html

Never heard of ADB...

Folders with files of mp3, wmv, mp4, pdf have been disappearing from the SD card after a while also.

It's really odd. Could it be the SD card? I contacted the guy I bought it from on eBay and he says it was ok when he sold it to me...

When I choose 'No' on some transfers, some files play, some files appear to play then close (screen returns to app menu) and some give me the message ' This video cannot be played'

I don't to mess around with any modifications or roots as this device seems to be messed up as it is!

I've contacted Samsung and Panamoz now and I'm looking to return it and get a refund, if not they should send me a brand new one where I'll sell it for a cut price on eBay or Gumtree, or here!
[Galaxy Tab 7.7 General] teiglin:
Files disappearing makes me think the SD card is bad, especially combined with randomly misreporting its size, and the files failing to play unpredictably could easily be a sign of data corruption. Personally, I never buy SD cards from ebay, only ones in retail packaging from a respectable brand--I'm a big fan of SanDisk microSDs as they generally outperform their speed class. Flash memory has a great deal of variance in quality, and cheap memory is much, much more likely to fail (although all memory will fail given enough p/e cycles). It's not impossible that a bad device could be randomly deleting things I suppose, but it seems exceedingly unlikely to me. Rooting or not really has no impact on this area, except I suppose for the added possibility of user error.

My first suggestion would be to try playing some of your videos that you know are good (and can for sure be played on smartphone/tablet hardware) off the internal memory and see if you experience similar problems. If you do, then it's probably a bad device and you can go ahead with the return. If you don't, it's almost certainly the SD card you're using, though I'd recommend trying a couple of others too, just to double check.
[Galaxy Tab 7.7 General] uncle_buckman:
Thank you so much for the help, it turns out to be the SD card I bought used from eBay. I'm currently looking at Amazon for a new one.

Samsung 32GB Class 10?

SanDisk 32GB Class 4?

Kingston Class 4?

They're all SDHC, will the higher class make a difference on this tablet?

EDIT-

I bought the Samsung
[Galaxy Tab 7.7 General] teiglin:
You're welcome, glad you tracked down the problem. :)

The class rating of a card is a (very loose) indication of its speed--it states a minimum sequential read throughput it is able to attain in MB/s. Higher speed classes are useful for applications such as high-quality video, and is generally useless for smartphones and tablets--not to mention that in many cases, a card will attain higher sequential throughput at the cost of random access speed, meaning the actual performance in a tablet will be worse.

The SanDisk class 4 is the one I have in my Tab right now, and I have also used the Samsung class 10 and both are excellent products. I haven't used a Kingston SD card but they also make decent memory of other types, so I wouldn't expect any problems with it. Scanning the user reviews is actually a good idea too--if the cards are frequently faulty or underperforms, it will show with a lot of bad reviews. So between those three, I'd just go with the cheapest.

Bad flash memory just happens, even to the best of cards, which is why it's good to buy from a large vendor like amazon and have a reputable manufacturer, so you have places to turn if your card is bad.
[Galaxy Tab 7.7 General] uncle_buckman:
Thanks, I cancelled the Samsung and ordered this one;

[Galaxy Tab 7.7 General] uncle_buckman:
Quite simply because it's un-branded and looks exactly like the one that's causing me problems right now.

Plus its a class 10 which is apparently unnecessary for a tab like the 7.7

I have a strange issue on my P6800. When connected to WIFI, it sends and receives some data every 2 seconds. Has anyone else noticed this?

I checked the logcat and i get the following every two seconds.:

DEBUG/WifiStateMachine(2872): ConnectedState{ what=65619 when=-4ms arg1=11 }

It's not any of my apps, i have the same apps on all my Android devices. I even did a factory reset, to delete all my apps and data, but as soon as it booted up it started doing it again.

So is it just me? Maybe the stock SEB rom? If no one else has seen this, then i will just update to another region.

Charger in - screen on

This seems like a general android question but since my device is the p6800 i figured this is a decent place to ask:

When I plug in the charger, or unplug the charger the screen is automatically turned on... this drives me insane. Anyone know how to turn this off?

Also, when device is max charged the screen comes on... this kills me.. I also want to turn this off if possible.

Any ideas. Thanks
[Galaxy Tab 7.7 General] Theory:
I don't have a solution. But you can at least do this: Go to Settings>Applications>Development and uncheck "Stay awake". Then go to Settings>Screen>Timeout to set an appropriate time. The next time the device is fully charged and the screen comes on as usual, it will at least sleep after the timeout period.

My Phone Explorer way better then KIES

Try My Phone Explorer (You will find it on the Market)

I'm lucky to have found such an app. I can sync my data be it call data, messages, pictures, calender... anything to my PC and forget about data getting lost. I would highly recommend it to the fellow users to use this application to store your data. It can connect via wifi, bluetooth, USB etc so its really simple and easy.

Works great with Outlook 2010, syncs Contacts, Calendar & now Tasks & Notes with Outlook seamlessly

[Galaxy Tab 7.7 General] burhanistan:
Check the threads about rooting. You have to be rooted for any downloaded apps to write to the external SD card.

But anyway, with all the onboard storage space you don't need to bother moving actual apps to the SD card...just use that for media files and the like.
[Galaxy Tab 7.7 General] EduardS:
I'm rooted and have applied the platform.xml patch. Although apps can write to the external sd-card, it seems impossible to move apps from internal storage to the external sd-card. Anyone with a fix for this?

Help with sdcard write permissions how-to

Hi,

Great guide BTW. I have already fixed my tiny system font issue and will move on to a replacement launcher shortly :-)

I'm currently following the guide to modify the config to allow apps to write to the external SD, and my non-stock file manager (File Expert) will not open the xml file for editing. I take it that is because my file system is mounted ro? I know the how-to says "check that the fiel system is mounted rw" but it doesn't say how to do that.

How How How?

Thanks,

Chris
[Galaxy Tab 7.7 General] cneal:
Great tips, keep 'em comin'!

Have now purchased and installed ADW Launcher Ex, and loving it. I've decided to go icon-only (not use widgets), and my 7.7 now flies compared to before with TW Launcher!

Two things:

1. would be great to fix the external SD write permission issue (can't figure out how to mount system partition as rw, or maybe it's another reason. The device is rooted but my file manager gives an error when trying to open platform.xml in an editor.

2. As my device is rooted I'd like to be able to increase the size of the system font without using an external app. I'll search around here for a how-to but if anyone knows I'd appreciate a pointer.

Thanks again for this great post :-)
[Galaxy Tab 7.7 General] burhanistan:
Some find it easier to simply copy the platform.xml file to their computer, edit it there (saving a backup of the original, of course) and then copying that back to the tab over the original.
[Galaxy Tab 7.7 General] Theory:
I'm not familiar with File Expert but I managed to edit the relevant files with Root Explorer (paid app). But as burhanistan says, the other way might be easier.
[Galaxy Tab 7.7 General] bobya:
Thanks

I just want to say thank you for the FAQ.

---------- Post added at 10:17 AM ---------- Previous post was at 09:58 AM ----------

you have to configure the mount option of file expert to mount read-write. From the menu of File Expert select mount, then select Mount Read Write

Then you can open the root folder again and it should be writable.
[Galaxy Tab 7.7 General] randomguy101:
Hi,first of all thank you for the FAQ.

[Galaxy Tab 7.7 General] EduardS:
After some research I guess this is a general Honeycomb issue and cannot be resolved. Am I right about this?

[Galaxy Tab 7.7 General] omarrabbat:
Don't use a font changing app like Font Changer or Font Installer, etc. Specifically those two don't overwrite the default fonts correctly & that's why you will see weird looking fonts sometimes (gmail app for example).

Best & Easiest Solution (requires root):

1. Download this rar file.

2. Extract the three .ttf files and copy over to your device.

3. Copy them to the system\fonts and overwrite the originals (I will give you a link to the originals).

4. If you want to go back to stock, download this file and do steps 2 & 3 again.

Galaxy Tab 7.7 3G not booting up

Hi, I have the Galaxy Tab 7.7 3G for like a month right now.

Last night, by mistake I forgot that the Tab had its battery almost empty and forgot to connect it to the charger.

This mourning, when I woke up, tried to turn on the Tab, but nothing showed up. So I connected it to the charger, and the battery status was displayed but with clock in the middle! It stayed like this all the time, as if it got stuck or something.

I left it for an hour and then tried to turn it on, pressed the power button for like 8 sec., the display turned off and then again the battery status showed up with the clock in the middle.

So I disconnected the charger, and pressed the power button for a 8sec.. The "Samsung Galaxy Tab 7.7 " Screen showed up this time, but it stayed there!

Nothing else has happened, did this many times over and over again same thing happens and gets stuck.

Has something happened to my Tab? Is there a way to fix it?

Thanks in advance.
[Galaxy Tab 7.7 General] TonyBigs:
Try leaving the charger connected for a period of time without removing the charger. It is possible the battery is discharged to the point where it needs to be charged to return the battery to its safe operating condition.
[Galaxy Tab 7.7 General] ahasbini:
Thanks for advice, I have tried this from during the day, it's been connected to the charger for more than 7hrs but still the same thing is happening.

I would like to say that this has happened with me but with my HTC HD2. I've noticed that different usb cables take different "speed" to charge the phone into a good state.

Could it be of the lengthy cable of the tab's charger, or a certain corruption due to the boot because of low non-operational battery state?

Thanks in advance.
[Galaxy Tab 7.7 General] suwandiapr:
How about long press to your powerbutton? 30 seconds or more..
[Galaxy Tab 7.7 General] ahasbini:
Well I've tried that but even before the 30 sec. finish, it gets to the same ol' problem. Thanks for your help though.

Its been connected for a fresh 7 hrs straight and still having the same problem. I'm afraid of ending up to flash it with its stock rom if there is no way to fix it. Has this ever happened to anyone from before??

A little info of a similar case would be of great help, my initial post, which is my case, is post #56. Thanks in advance.
[Galaxy Tab 7.7 General] 九千.:
I have similar case before. Once I left the wall-charger in the office during a long holiday and I accidentally drained the battery to the floor. The data cable which could be able to charge my 7.7 normally failed to charge it up at this stage.

So I thought of buying a traveller battery pack to charge it up as I might need it sooner or later. The salesman in the shop was nice enough to help me find a suitable pack for my 7.7. Turned out only one brand that was capable to charge up my tab at this stage.

I attached a photo of this pack so that anyone who are interested to acquire a traveller pack for your power-hunger 7.7 could refer to it. (

Note this is a 6600mAH capacity model. Any other model with less capacity might not be able to charge 7.7 up from total-drain).
[Galaxy Tab 7.7 General] ahasbini:
Where you able to turn your Tab back on through the battery pack, like after when the charger failed to turn it back on?

And how (like connect it through a cable or another way)?

Thanks in advance.
[Galaxy Tab 7.7 General] 九千.:
Yes, it was able to charge up 7.7 when the "data cable" failed to charge it back. I haven't tried the wall-charger last time though.

This traveller pack comes with three cables and many replaceable charge heads to connect your pack to most phones and tablets from Samsung, Apple, HTC, Nokia and Moto, etc.

The downsize is that it is bulkier than other portable chargers, but this is the only one that could charge up my 7.7 from battery-dead-state.
[Galaxy Tab 7.7 General] ahasbini:
Sorry I'm asking you too many questions, I just care sooo much about my tab. Have you realized any difference in the battery life of your tab after using your traveler battery pack to charge it up?

Believe me this the last question :P Thanks in advance.
[Galaxy Tab 7.7 General] 九千.:
Hey don't worry about that. We are supposed to exchange opinions and views here. Feel free to ask.

Nah I don't see a notable difference in battery life after I use the battery pack. Besides I don't use that battery pack too often. There isn't too many occasion that my 7.7 need it.

Often case that was my friends who need it. So I always have the iPhone/iPad charging head ready for them. :rolleyes:

I would like to ask..can the samsung tab 7.7 really can be charge by data cable? because every time I plug my tab on my laptop...its not charging...

Thank You,
[Galaxy Tab 7.7 General] burhanistan:
It can "trickle charge" if the device is powered off (or perhaps only if the screen is off). It will take far more time that way to charge than using the AC charger.

Aftermarket kernels can adjust this, possibly, to allow for more effective USB charging but I don't know if there's anything stable for that yet.
[Galaxy Tab 7.7 General] bedwa:
I plan to add it to my kernel, but a standard workaround for USB or non Samsung chargers is if you have the HDMI adaptor, plug it in, then plug the charger into the power port. Charges faster than MTP trickle alone. ;-)

My Tab makes phone calls yo! (GT-P6800)
[Galaxy Tab 7.7 General] dfkt_:
Alternatively, one can only install the Samsung USB drivers and leave the Kies bloatware off one's computer: drivers.softpedia.com/get/MOBILES/Samsung/SAMSUNG-USB-Driver-1480.shtml
[Galaxy Tab 7.7 General] 九千.:
Have you installed appropriate? Sometime it would make a difference. I could charge with this data cable while the tab is on.
[Galaxy Tab 7.7 General] Theory:
It depends on the voltage* of your USB port. The normal voltage* is low enough such that if the tab is on, it will only be a very slow trickle charge and the icon might show that the tab is not charging.

*Edit: Should be amperage
[Galaxy Tab 7.7 General] dfkt_:
It seems my stock firmware doesn't charge over the data cable at all, no matter the amperage the USB port provides. Once I switched to the Noob 2.1 ROM, it started (trickle) charging. Not sure that's a good thing, though - since I read on Battery University that Li-Ion/Poly batteries prefer a faster charge.
[Galaxy Tab 7.7 General] Theory:
My stock firmware (though rooted) will not charge over the data cable if I plug it into my laptop's USB (including USB 3.0) port, unless the tab itself has been switched off, in which case it will charge, but fairly slowly.

But the USB ports on my desktop (Gigabyte X58A-UD3R motherboard) can to supply current above the normal USB specs (see this), and are able to charge my tab over the data cable.

But in general, my impression is that we are not meant to charge the tab over the data cable.
