Here is my review for those considering to buy one.

Typing on the Galaxy Tab has been a pleasure especially when using Thumb Keyboard, but there are moments when a physical keyboard is needed. When I am sitting in lecture and I want to take notes with my Tab using the onscreen keyboard, the Professor may think that I am texting in class. This not only leads to unnecessary embarrassments, if he or she calls me out in front of the other students, but also makes note-taking inefficient; I type slower with the onscreen keyboard than with a regular keyboard. I resorted to carrying around my full sized Apple bluetooth keyboard and trackpad with me so I could take notes and navigate the Tab more efficiently but alas, it led to people constantly staring at me because of my awkward setup and as you would imagine, portability was an issue as well. What’s a guy to do? Luckily I found a solution, a bluetooth keyboard within a case! Check out my video review after the break:

http://www.youtube.com/watch?v=4srLChySYio

Overall Impressions:

The bluetooth keyboard/case has been a tremendous productivity tool. I’ve managed to type this review in its entirety with the keyboard and it has been a great experience. As I mentioned in the video review, there is a slight learning curve to it but after that, you will be typing as fast as you do on a normal keyboard. The battery life is exceptional! I have been using this keyboard on and off for about 4 days now have yet to plug it in to charge it. This keyboard, coupled with a few other apps, makes typing long emails and controlling the entire tab easy and intuitive. It’s now a pleasure to sit on Google Talk and chat with my friends and have long conversations with them using this keyboard; it feels natural. So if you are in the market for a portable keyboard for your Galaxy Tab and want to save yourself the embarrassment of carrying around a full-sized keyboard in your backpack, then go ahead and pick up one for yourself. I think with the perfect sized bluetooth mouse, you basically get a mini netbook. Prices due vary ($40-$90) so shop around. I recommend using ebay or google shopping to get the best deals. Just search for Galaxy Tab Bluetooth Keyboard Case! If your in a rush to get one, here’s one from Brando.com.

Recommended apps to use with this keyboard (Available on the Android Market):

-BlueKeyboard Pro: allows you to hide the standard keyboard when you are typing with the keyboard connected.

-Widget Locker: great for getting the homescreen in portrait mode and for waking/unlocking the Tab by using the back button on the keyboard

-Task Switcher: AMAZING tool used to program quick keys to launch your favorite apps as well switching between them. Much better than holding down the home button.

If you have recommendations for a good bluetooth mouse, leave a comment or email me at ayman@thegalaxytab.com!

Nice review! Glad I ordered one...seems just right for on the go!
[Galaxy Tab Accessories] masbego:
Thanks for the review, its been 3 weeks I've ordered from brando, the package already left hongkong..but when I tracked in australia, the package still not in yet..

Why is it take long time??
[Galaxy Tab Accessories] CASz:
Mine was shipped to Canada Feb 21st and just entered customs on March 8th. I guess shipping takes awhile.

Those app tips are very helpful OP.

Finally arrived so I did an unbox video http://www.youtube.com/watch?v=x1FvXRajZUU Glad I got it.
[Galaxy Tab Accessories] Archer:
Great review. I ordered one before my tab turned up and had an initial knee-jerk that I didn't like it. After using it for some IM though, I absolutely love it. I was lucky enough to pick one up from Amazon for £25, with free delivery, which is the cheapest I could find it.

It really does turn a big phone into a netbook.

Also, I've not got any 3rd party apps to suppress the keyboard. I just press the keyboard "go away" button when relevant.

If anyone is questioning getting one of these then I'd strongly recommend it. I've only had my tab for just over a day and this thing has already given it a new lease of life!
[Galaxy Tab Accessories] Timtown:
FWIW, I ordered mine from Brando back in February (10th, I think) and just got it today (22-March).
[Galaxy Tab Accessories] TheChampJT:
Nice find on task switcher, makes having the keyboard 10x better

Found a better app for the soft keyboard replacement, check out null keyboard.
[Android Software Development] greydarrah:
I'm working on an app that has about 15-20 questions for the user to answer. Input is handled by EditText and Spinner widgets. I've played around with a number of different XML layout designs (Linear and Table) and can't seem to both make the text input either fit or look well on the phone screen. Here's an example (made up, but similar in length) of some of the text that I'm working with:

I have a relative that has two

green

eyes. (the blank would be a spinner)

My shoes

don't

fit to tight after jumping on purple trampolines.

My dog

did

have flees last year.

If the query sentences are long, it's because the question is long and I can't make it any shorter.

Does any design oriented guru out there have any suggestions as to how I might look at laying this out and have it look decent? If you know of other data intensive apps that you could point me to, I'd be happy to check them out.

Thanks
[Android Software Development] Chalup:
Are you trying to fit everything in one window?
[Android Software Development] greydarrah:
I'm going for one scrollable screen (scrolling vertically, not horizontally), but I'm willing to consider anything.
[Android Software Development] Chalup:
Have you messed around with a ScrollView? http://developer.android.com/reference/android/widget/ScrollView.html

What if you put a vertical linear layout inside of a scroll view, then have each child of the linear layout be whatever views you use to handle the questions?
[Android Software Development] jgittins:
I think it would be easier to have each question on a different screen. Have some kind of counter at the top, like "question 1 of 15", and have next & previous buttons at the bottom.
[Android Software Development] greydarrah:
I do have my table wrapped in ScrollView, but I'm going to try the linear vertical and see how it looks. Thanks.
[Android Software Development] greydarrah:
I didn't even think of that, which is why I started the thread. Thanks for the idea.

I'm still open to any other design suggestions anyone might have.
[Android Software Development] Chalup:
Good idea. You could have it so that upon answering a question the user is brought to the next question. I'm picturing the initial setup activity that opens when you first turn on an android phone

Its the nick name that Google's likes to put on their phone operating system version. On every .1 they update they release it with a nick name. So Gingerbread is given to Android 2.3, Froyo was given to Android 2.2 and it just does down the line to 1.5 i believe.
[Android Software/Hacking General [Developers Only]] Smokem_I:
Yes Gingerbread is the new Android Operating System. It is also known as CM7, 2.3.2, or 2.3.3. It is much faster than the older OS! I am using it right now.

[Desire Accessories] doom_71:
Hello to all you out there.

I have been the proud owner of a desire for about eight months now. I just got a new car, Hyundai i30, and i am planning to put a BT carkit in it. Can anyone tell me about their experience with, preferebly, parrot carkits?

Tnx
[Desire Accessories] timt1961:
I have a parrot MKi9200. Reasonably happy with it, less so with parrot support.

Sync works, iPod play works as advertised. Software is a bit buggy, but nothing problematic. I recommend you get a good installer for it, though
[Desire Accessories] Yagoozy:
I also have a parrot MKi9200 and works very good. Also with the HTC Wildfire from my wife.
[Desire Accessories] mrtiggleworth:
as mentioned get a good fitter or someone who knows what they're doing. the i30 isn't to bad to take apart to run cables.
[Desire Accessories] fragargon:
hi, got a parrot ck3100, good sync, adr book and stuff to phone but not a2dp (so no music through it).
[Desire Accessories] juicy_jozy:
I also have the 3100, and it works like a charm with my desire (latest radio and cm7).

Syncing and connecting with phone are automatic, voice dial works and parrot is easily updateable with a bluetooth connection. And above all, voice quality is perfect
[Desire Accessories] martijn_bakker:
I've got the CK3100 and (as people have mentioned above) it works well with the desire.

A minor issue: GB roms appear to have a problem with BT where the phone doesn't immediately switch back to it's phone speaker when the connection to a headset/carkit is lost. I believe this is is GB issue. I've never experienced it before I started using GB roms.

Also, as people above have pointed out, it's probably worth getting a system that supports A2DP audio playback too. I'm using a separate Tunelink device for that.. and it works. But using two separate BT device to connect to the one Desire is a bit awkward.
[Desire Accessories] chrrh:
I am using a PARROT MKi9000 with my Desire.

speech recognition is nearly perfect.

I use it for streaming music/audiobooks over the car-speakers, too without problems.

Installed it by myself without problems. Plug & Play.

9200 is the best you can buy imo, does it all(at least all that you can expect from a car kit), and parrot releases updates frequently.

[Desire Accessories] Xrolley:
Hi there,

I use the MKi9100 in my Fiat Grande Punto and it works very well with my Desire.

I wouldn´t recommend to use the music playback function via bluetooth, though, as the sound quality kind of sucks...:eek:
[Desire Accessories] xlenz:
Yeah, listening music throw bluetooth really killing me))

I should always choose between quality or battery life :(

[HD2 General] T-Macgnolia:
You sir are the man. :)

I personally do not have any over heating issues with my HD2. But there is so many people here on XDA tbat do. So your work will be greatly appriciate and followed here. From what you have posted you may just be onto something that will be very useful not just to HD2 owners but to a large veriety of smartphone and maybe even tablet owners, present and future. I too find the the epoxy resin that HTC placed around the chip odd. It is almost like HTC did not want this part of the hardware to be replacable. But make you have to buy a whole new main board, corperate crap :mad:

Anyways please keep up the good work and I will be following this thread very attentiavely. So please do post back here with your future findings.
[HD2 General] d3m0n1:
The epoxy resin is there to hold the CPU (which is the biggest and probably the heaviest part on the PCB) in it's place, and thus making it more resistant to mechanical forces (such as accidental drops, shocks, etc...).

It could also be, that HTC wanted to prevent access to the CPU-s I/O pins, making it impossible (or at least very difficult) to desolder it. This way it is difficult to "reaserchers - hackers" to chart a schematic diagram of the connections between CPU, flash chip, ram, etc..., or to attach logic probes to the IO lines, and that leads to being difficult to make software hacks such as HardSPL, or sim unlocking, etc... I know that there are other methods to connect to CPU (such as JTAG), but fewer options mean, less chances to succeed.

B.r.:

[HD2 General] xlr8me:
This is an excellent post and thnx you for your testing and investigation. Do let us know how your unit goes within a week of real world testing.

The engineers @ htc should have incorporated a better CPU cooling solution on hd2. Your testing and modifications are a wealth of information.
[HD2 General] motoi_bogdan:
thanks for the support

The resin on the cpu has a higher melting point then that of the solder joints of the actual cpu to motherboard. I guess the reason for it's presence is that when the phone is hot (and HTC knows the cpu can gen hot) the solder joints become less mechanical resistant, they could be more easily broken. In case of a BGA mechanical failure, the resin however would pose a problem as the chip can't be desoldered safely or even reheated. I took a risk there.

I don't think HTC didn't want us to desolder the chip because of JTAG pinnout mapping. Even with acces to the pins, it would be very hard to find the pins without some form of CPU datasheet. Same goes for CPLD for example.

Anyway, at this time i still don't know if either reheating or making some sort of cooling system helped me to solve this problem. So far, still good, not a single problem noticed so far. I can now reflash the phone, before the procedure, i experienced that vibration pattern during a flash. I've put android on it, stress test it even more, i'm now trying to play some 720p on it. It still heats up, it feels as warm in the hand as before, but for whatever reason, it doesn't restart anymore.

However...more testing still to come.

On another note, i'm now working on a broken Eten M810, some CPU problems. It this case, the CPU doesn't have that resin, however the nand memory has. :p Different brand, different choices.
[HD2 General] modex:
my phone stuck after it fall on the ground facing the LCD down on the tiles. there is no physical damage the screen is in perfect condition, touch screen works very well but after it hits on the tiles my phone is getting stuck randomly.. since its been a month after the incident i have tried a lot of ways to fix this even tried removing all the parts except the LCD and digitizer to see if there is something lose inside but still not fixed.. :( i m noob to all this dont really know names for all the parts. the reason i have found for this freeze is due to a little press near sim card where the main board is. even a very lite press from the back near sim card results the freeze..i can say this because it wont get stuck if didn't touch the mentioned area, every time when its stuck i have to remove battery cover and press the red button and it will get stuck again if i put the cover back after it boots (becouse when putting cover back it definitely press the area....so i have to be very careful to put it back) so can anyone help me on this? what could be the problem..:( sorry for my english :)
[HD2 General] xlr8me:
An interesting observation. I have been in air conditioned room last 4 hrs and it really cools the hd2 down. Perhaps the glass digitizer is quite conducting and non-insulating.

During summer hot days I have hit 42C without any issues. Dont want to hit 45C though this hd2 is a beast.. Imagine staying at 1100MHz o/c all the time... aiiii caramba...:p we could cook some eggs on it.
[HD2 General] electronspeed:
Yeah, I've experienced some of the freeze while HD2 got hot and stayed like that until it cooled off. I've noticed that when I try to charge it in the car and run google map it tends not to fully charge as it should but it heats up after a while until it becomes unresponsive then i'd let it cool off again.

Hope it hasn't effected CPU's connections much but at this point I'll have to monitor its heat situation to prevent future disruptions.

Good work/thinking on the "cooling adapter" , i've seen similar approach on IBM's graphic card which fail due to the same reason and ppl would heat them up to reconnect chips connection to pcb.
[HD2 General] motoi_bogdan:
the back of the lcd display (the actual lcd, not touchscreen) is made of metal and on top of it there is some copper foil. So.. yes, if you cool the screen it helps cools the cpu. However when i disassembled my hd2 i noticed that the actual cpu isn't in direct contact with the metallic back of the screen. So, although it could help if you cool the screen, it isn't very effective. I adapted my "cooling" pad to have the cpu thermally connected to the back of the screen via that DIY aluminium and copper foils setup.

@ modex if the phone drops, the bga connection between either the qualcomm chipset or nand memory (the 2 largest chips onboard) could get damaged. As we know the connection between the cpu (inside qualcomm chipset) and motherboard can be faulty or get that way over time, it's a prime suspect in your case. It is very difficult to predict the outcome if you send in the phone for repairs or have it reheated. I know of no service center that can effectively reball the cpu to the motherboad (means that the chip would actually have to be removed, connections remade - chip resoldered)

My phone is still doing well, one week after the intervention i made. About 14 roms installed, running wp7, android builds, custom wm 6.5, ubuntu and etc. Not a single restart or freeze. It does heat up, but it's now spread over it's surface.

From what i can tell, the diy heatsync helped more then the actual reheating of the chip via hot air station. If in the future, someone else without a warranty to the phone, would try making a similar hack to the phone, we will know for sure if the problem can be solved by simply cooling down the cpu to some extent.
[HD2 General] januszgorlewski:
When i will get back from my holiday i will try your thing on my hd2 as it does all the freaky parts even when doing nothing.

today i noticed 7vibrations and got scared, got artemis as a backup, using now, but after a week will try re-solder and give back feedback.

still-after few years of silence in doing electronics- i got my hermes back to life-white screen due to faulty front pcb keyboard, had tp2 and exchanged for hd2-want to see it fully working for the price i paid for it.

regards
[HD2 General] palmsole:
Very cool thread...reminds me of days of palm pda when people were more technically

Inclined. Will have to try this out as well.:D
[HD2 General] januszgorlewski:
Just one silly question.

I mended pcb on hermes using heating torch(butane powered)

do you use the same sort of thing or special ones?
[HD2 General] motoi_bogdan:
yep.. more than 2 weeks have passed and after i completed all possible tests the phone still works ok.

About 22-25 roms flashed (wp7, wm6.5, android, ubuntu) phone was used either normally or heated with a hair dryer. At about 30 degrees ambient room temperature, i run some 720p testing and manage to run sample videos until battery died out, then rerun the videos while charging (charging induces more heat also).

In all those 2 weeks i had only 2 restarts, both in wp7 (can't remember what rom version did that) and both occurring when i was setting up the phone after the phone update. Phone was cold however. I didn't manage to produce more restarts either when the phone heated up or i tried running intensive apps on it. Guess it was software related.

So.. i guess it's over with this problem.
[HD2 General] profahmad:
This thread is awesome. I've opened my HD2 a few times in the past week to replace the LCD. Between the first time and opening it last night the LCM (LCD and touchscreen module) was slightly loose from the chassis so the screen was protruding a little and the front AP buttons were sunken. This was the case for a period of about a week, during which I noticed the phone would get very, very hot towards the bottom on the posterior surface, beneath the battery cover (around the area of the main board). Last night I properly assembled the whole device and it's now completely flush. The overheating doesn't seem to be occurring now.

I wasn't experiencing any restarts or lockups during the time it was overheating.

When I can get hold of the materials I'm definitely trying your heatsink. Thanks for sharing this.

Packaging Reliability - 7 vibration lock-ups

Thanks facdemol for your investigation and sharing.

I have been typing a lengthy description of what happend to me and then my browser hang - annoying so now only the short version ;)

My long awaited factory fresh HD2 that failed exactly as described within 2 month at winter season. I was lucky get the original SPL back after storing it on the balcony at minus 5 and flashing from SD. Please mind, that for me the issue was heavily accelerated with the HD2 plugged in.

Yesterday I got mine back from warranty repair with the main board swapped. Since I am now anxious about this to happen again I asked about similar experience from others which has been denied. After reading this I recommend starting a petition, as this is obviously an wrong thermal design. I work as an packaging engineer and can access this as x-ray, ultrasound microscope (water bath only) and infrared imaging. Even though I dont have the time start this petition I would offer to help putting some serious reliability research behind.

So you could donate malicious hardware for inspection, as mine is still in warranty.

Few years back I had a good RMA experience with my Canon camera that died in warm humidity. After some research in the net I found the policy that all models will be replaced for exactly this failure -no matter when it occurs, as it was a design error (wrong material for CCD attach at this case).

So please people with thermally instable snapdragon devices STAND UP and ask HTC for seriously handling these mistakes. They should replace even after the warranty expiration if they only admit, it was their design flaw...

I for myself will probably try to stress my repiared HD2 in order to have this failure again and then I can opt for exchanging the device. Buth then, what device to buy? For the dual cores this might be even worse. Suppliers do not have long enough life cycles for their products to really do good redesign.

Keep it up
[HD2 General] januszgorlewski:
I had 7 vibrations while on the plane, just switched on, play solitaire 5min, then reset-7vibrations, took battery out, start it up, same 7vibrations, about five times same cycle.

Then i thought, ok I am done now-it's a brick, as PC's have BIOS which can tell you by beeping what the hell the problem is. In this case, no idea... Then i found this thread.

@ facdemol I might try only a heatsink - reheating cpu not needed, right? but i will wait for insurance exchange of my phone...

sir first of all i want to thank u for this excellent post . . . . Cn u tell some other easy material than mica foil pads which may b available .. I hav same prob with my hd2 with expired warranty .
