Does anyone have this dock..

laying around in house to see if it will work for our G2X?
http://www.amazon.com/Samsung-ECR-D1B7BEGSTA-SGH-i997-Multimedia-microUSB/dp/B004WOBN3I
I know its not for the LG, but its a micro USB and has everything working for it including the size ( i think).
If we can not find a decent LG dock, then this one might be a good option... but dont know if it will work for our phones or not. So hoping someone has one laying around at home that they can try out and report back.

Looks like it works with the Infuse 4G. Compare sizes and see if it'll work.
Possibly. The Infuse 4G was huge:
http://www.sizeasy.com/page/size_co...tion-vs-T-Mobile-G2x-vs-iPhone-4-vs-Infuse-4G
If there is a backplate, it should fit in there with room to spare. Might not be a good fit but it'd work. For $50 bucks though I'd think I'd want something tailored specifically to my device.

agreed... i rather get something for the phone.. but doesnt look like LG has any decent docks that does activate the dock features and all.....
from all I keep reading on the desk dock.. it doesnt really do much other then hold it in place.

I don't know, the dimensions given by Amazon are Product Dimensions: 4 x 3.5 x 4.5 inches which, after you consider the excess on the side, might be a snug fit. Although, given the specs I've found on the Infuse, either these dimensions are wrong or it's not for the Infuse, but more of a Samsung brand charger than a specific handset and, again, is labeled wrong by Amazon.
No matter what, the mini USB is in the correct location. And even if it's a little wider, it still looks better than anything offered by either LG or anyone else. If you try it or anyone else, post up. Cause I'm interested!

I will buy it and post a mini review for you guys, it looks like a perfect fit.

Any update on this? I too am looking for something JUST like this.

wow... nice dock.. and checking the sized.. the G2 is significantly smaller than the infuse.. this should actually work.. hazaaaaa. Did anyone buy this yet?
You can always return it to amazon with no issue if it doesn't work eh?

Why not one of these universal ones on ebay? Link to my search: http://shop.ebay.com/i.html?_nkw=un...+cradle&_osacat=0&_trksid=p3286.c0.m270.l1313
Particularly this one: http://cgi.ebay.com/UNIVERSAL-DESKT...689784?pt=PDA_Accessories&hash=item5d2ec60c78
They are soooo much cheaper and I would think reception to the cell tower (4G Internet) would be less likely to be interfered with if none of the rear surface area is covered. With my G2 I noticed that my connection speed and number of bars was a lot lower when I laid it flat on a table. When I either propped it up on the table, or held it flat with just my finger tips (basically leaving the back uncovered) the connection was fast and strong again.
I like this idea too because I can place it anywhere in the room for best reception and run an extension cable to it to keep it charged, while using the the 4G with wifi hotspot on my PC.
I wonder which is best as a homemade tripod. At those prices I could buy 1 of each and try them all.

Any update on this one Huntman? Dont know if you got this ordered or not... just curious

Well, I just purchased it. Used the super saver shipping (5-8 [email protected] charge) so I guess we'll know in 5-8 days.
I'll post pics and final judgement as to whether or not it works...

I have the official LG desk and car docks. The desk is not fancy, but it hold the phone up, you just have to plug the power cable in if you're placing the phone in the horizontal orientation.
The car dock is great, solid, great fit. But I may remove the magnet that tells the phone to go into "car mode", since generally that's not helpful to me.

can the car dock be mounted to my dashboard? i don't like sticking to windshield.

anyone pick this up yet?

I got it today... and it is sexy!!!
Now for the low down:
-Yes, the phone will connect in (w/o a cover on only)
-there is a gap though on either side, maybe a 1/4" at most
Even w/the gaps, I can still place it on it's side and the phone stays connected,
although, since it's being held up by the slim-usb connector, I can't see it being
good for the phone.
Now for the bummer (well, kinda) to get full functionality of the dock, you have to DL 'Samsung Home Dock' app from the store. Now, since it's free, you wouldn't think it was so bad, until you find out itlooks for the specific samsung fingerprint in the build.prop in order to install (to DL from market as well, I just took the apk file from xda.) So, now I need to find a build.prop that will sneak me through this little speed bump. Shouldn't be hard, just not enough time to search it out tonight.
Fortunately, the speakers on the G2x are so bad ass, even w/o the addt'l speaker built into the dock, it still kicks it out.
I'll get pics posted tomorrow after work.
Over all, considering our options, I think it's a winner!

Sorry, been swamped w/work. I've tried some customizing in the build.prop, but I don't have the experience to figure it out. So no go on the samsung app just yet, but I haven't given up.
As far as the pics, I've just got to UL to my computer to post them. Will do tonight.

Doesn't Mugen Battery offer one specifically for the O2x/G2x?

Here are some pics of the dock, with and w/o my G2x in it. I want to apologize for the fingerprint smudges that are all over it... Who am I kidding, all that proves is how much I love this phone and use it.
Anyway, on w/the pics.

Dock itself, sans phone[obviously]
rear view of dock. here you can see the built in speaker, speaker line out and the mini usb [power] connector.
A good [but very smudgy fingerprint-tastic] view of the phone in cradle.
This is a close up of the gap.
To be fair, as I've said in a previous post, I can set it on it's side while the phone is in and it doesn't sway at all due to how far in the usb connector fits. Still, I have to think it wouldn't be healthy to place it on it's side w/o some kind of cushion. I'm in the works of forming a silicone slide to custom fit it. Once I have time to do it right that is. I'll post pics after I'm done.
As far as getting the Samsung Desk Home to install, I still haven't figured out how to properly modify the build.prop to recognize it . I've got a post in the modding are of xda for assistance. The last thing I want to do is somehow brick my phone for a dock app [although I would LOOOOVE to be able to use that line out w/my google music beta as an alarm!] but no response yet.

[Idea] Super Antenna

I was wondering seen as how we have an external antenna couldn't you build something that attaches to it and improves phone signal or make a cantenna? Any suggestions on how to do this?
Sent from my HTC Sensation 4G using Tapatalk

I don't know how much help this will be but I love the DIY spirit so here are some of my ideas.
Connecting to the existing antenna array could be achieved by attaching wires into the existing contact points in the back plates, then route through the camera lens opening out of the phone. The wires will have to be thin so that is something to consider. i.e. more fragile at longer lengths.
The new antennas could be based existing off the shelf parts or from existing DIY projects for each respective technology, but AFAIK you cannot use a single cantenna type device. Due to the different frequencies used for WiFi/Bluetooth vs. GSM vs HSPA+. I am unsure about how many you will need as a minimum or if there are special power requirements between the different technologies involved here.
Power will have to be another consideration. Not 100% certain, but I believe to get these "super" antennas to be truly super, you will need to increase the power to them. This will of course lessen battery life. So that would be another consideration. This mod might spawn a separate battery mod/swap.
I am not sure if this is cost effective or not, but DIY doesn't always consider cost. Of course if you are planning on using this to power some autonomous super killer robot, that can record in 1080P, and stream back live VGA video using the hardware built into the phone this could work out pretty well.

What if you somehow took gold wiring like on the connectors, attached it to the connectors and ran it along the inside of the back cover?

I think the one above the camera hole is for wifi because I saw a youtube video of a guy that took some tin foil and stuck it in the hole on the phone where that connector would make contact and it gave him a really strong wifi signal. He took out the foil and the signal dropped. So I'm thinking that the connector on the top is wifi. The strange thing is I also have an unbranded euro/asian sensation and it has one less connector than the TMO us one (but uses the same mobile bands/radios) and when I use that cover on my US sensation there is no signal difference. So I really wonder what that extra one is for, since I have noticed no signal difference when using one over the other on the US phone.

Hey guys Ive been giving this some serious thought and here are a couple of my ideas on this....I am looking for some serious Beta testers for my ideas, there is no money compensation for testing just fame and prestige......PM me if your intrested in beta testing for me..hurry I have a feeling a lot of people are gonna want in and space is limited.

Maybe T-Mobile uses AWS bands for HSPA+? I'm not sure if that's even possible, but I don't know much about that stuff.
Anyway, I believe the antennas are:
Above the camera: Wi-fi
Below the camera: BT? (correct me if I'm wrong)
On the bottom cover: Mobile network
And @joemm Lmao!

No, My Asian sensation has the same bands as my tmo sensation. It has the AWS band and gets the same download speeds as my TMO version. If it wasnt the same bands I wouldnt even get 3g, I would be stuck on edge. Tmo's 3g and 4g(HSPA+) run on the same frequencies. So if you have a phone that doesnt have the AWS band and the phone supports 3g and 4g you will only get 2g speeds. I believe All the the sensations first released had the AWS bands. I think only now are they starting to release versions with different bands. I know a while back a sensation passed through the fcc with att bands. Maybe those are the ones we are seeing popping up on Bell now?

Hmm, not sure how good this idea would be, but it's worth a shot
I'm thinking as the antenna has to be of a specific length to work, this length is determined by the frequenzy of the signal
Here is some examples : http://www.air-stream.org.au/wavelength

I have a new back cover coming and I might due some experimenting with the old one.

ive stuck tin foil in the back of it touching th ebottom two connecters and ive never suffered from death grip since , going on 2 weeks now :0

It should be possible if we could get a flexi pcb that we stick inside over the exisining connections and route outside and fold around that sticks down. I dont think we need more power, just a increased area. Should be easy to do.

Tear down pics of the Verizons S3

Well not sure if there is a thread like this yet, but I figured I'd post it up in case anyone wants to see them
The actual reason I had yo do this was because today I went to take a picture of my little kid (he's ² months) in his bathtub and he kicked my s3 out of my hand, and into his bathtub. So I pulled it apart to dry it out'

Is there a warrenty sticker anywhere on it? I noticed there isnt one covering one of the screws like I read about. I did notice there are what looks like white stickers covering some holes. I was going to take the screws and back under cover off just to have a look around but I was afraid they have some hidden shenanigans that would void my warrenty.

Just jizzed in my pants..nngghhfnfnfnfkdkd

Does it work now?

Wow, you're a lot braver than I am! Hopefully it all works!

nope no warranty stickers.
those little white circle stickers on the back cover, are covers for the antenna connections (similar to what you see on a wireless laptop card.)
& yes the phone is working excellent.
in regards to the little antenna connectors, i actually separated my RFID chip & antenna from my works ID (we have HID/RFID badges to let us in & out of the building)
I soldered a laptop antenna connector to the RFID antenna, end (allowing both ends of the RFID antenna to connect to the chip, but then on the 1 end there is a off shot with the wireless antenna connector) & i connected that to one of the antenna points on the phone.
before doing this i only received 1 bar with wifi in the farthest part of my back yard. not i get 2 , also i can hold my phone 4-8 inches from the works badge reader & it read (so its range increased as well) normally i would have to lay my badge on it & move it around a little bit
so win win 2 birds with 1 bullet (thats a inside joke that maybe a few will know )
i wish i was able to put the NFC chip in emulate mode so i could just emulate the work badge, but this solution turned out to be better (for now)

Good job

Obviously the nfc chip is in the battery lol I just bought a 4500mah extended battery. I wonder if there outs anyway to swap the NFC antenna to the new battery? If anyone knows , I would be happy to test it out. I guess I will have too Google it to see the possibilities!

GPS Antenna Fix for desire s. + Wifi boost

GPS FIX FOR HTC DESIRE S
FIRST OF ALL! This is not my idea! Original thread: http://forum.xda-developers.com/showthread.php?t=2263078
I just wanted to make a better thread with pictures so people can see it better
And i don't actually use this phone.
Just using my old nokia
Guys i want to make a clear instruction for you if you are having trouble with your gps.
The problems with the phone before i did the fix:
- GPS not locking at all!
- GPS can't find any satellites!
- Endless waiting just to find (with luck) 1 satellite!
And now after i did this fix:
- GPS finds 5/6 satellite under 1 minute. (if you are in a good area sometimes 7/8.
- GPS Locks constantly. even when it finds less satellites.
- Navigation works perfect
And WIFI is now stronger. Now i can connect to the router from a longer distance. outside the house the wifi router still gives me full great signal
did not effect the battery life
Warning!!!!
Before You Begin. Iam not responsible for broken devices. You just gotta be gentle with it! And use your brains
Instructions With pictures:

I have read in the forums that the battery cover is also cooperating with the GPS. I couldn't find anything good in google that shows where the gps and wifi antenna's are. But the good thing is that this fix works for me.

thank you soo much! Tried it today and worked!
I also put aluminium in these antenna's.

I can't watch the youtube video, it says "private".
The pictures' quality is very poor, couldn't you make better ones? Thank you
And, last question, do we have to unscrew something to open the phone in that way?

Thanks a lot for sharing. It fixed my WiFi!! It was broken after severel throw downs :victory:

It's not so easy to open the camera cover, because of the glue under the cover.
I put two little pieces of aluminium over the contacts, but the wi-fi cover doesn't seem to be changed.
I'll try later with the gps antenna signal.
Anyway thank you for the tips and the guide.

I noticed a boost on my 3G signal level when I bent a little bit those pins under the batter cover, then I added two small pieces of aluminium foil on the battery cover, over the "golden" contact pins

Warning against this mod!!!!!
I would be seriously cautious about modding your phone in this way, you can cause damage!!!!
Anyone who knows about transmitters will tell you that a transmitter needs a tuned antenna or it will suffer poor performance at best and damage at worst!
The gps unit although not a transmitter is very close to the other antennas and sticking foil inside your phone on just that antenna could still cause reflection of RF energy from the other units.
modding the antennas in any way of the transmitters within the phone is even more likely to cause damage, adding the foil changes the electrical characteristics of the antenna and what is called "SWR" (standing wave ratio).
When an antenna and feedline do not have matching impedances, some of the electrical energy cannot be transferred from the feedline to the antenna. Energy not transferred to the antenna is reflected back towards the transmitter. It is the interaction of these reflected waves with forward waves which causes standing wave patterns. Reflected power has three main implications in radio transmitters: Radio Frequency (RF) energy losses increase, distortion on transmitter due to reflected power from load and damage to the transmitter can occur.
So, mod your antennas at your peril.
Bending or cleaning the spring contacts that connect to the antennas will do no harm and could actually improve the connection but anything else comes with potential risks.
Steve.

Thanks Man! My wifi signal is now much stronger!
But sometimes when iam in a bad area the wifi drops a little bit... and goes up again.
The gps fix worked a bit faster. And my 3g boosted up a little bit.i have no idea how that happend but it's awesome!
It didn't give me a huge boost but it kinda boosted every thing a little bit up!

Thanks, this boosted all my signals, as I didn't know yet where the antenna's were located.

Tried this fix but honestly it didn't improve any signal, it did not make it worse either. Maybe it's a aluminium foil quality thing

I would be seriously cautious about modding your phone in this way, you can cause damage!!!!
Anyone who knows about transmitters will tell you that a transmitter needs a tuned antenna or it will suffer poor performance at best and damage at worst!
The gps unit although not a transmitter is very close to the other antennas and sticking foil inside your phone on just that antenna could still cause reflection of RF energy from the other units.
modding the antennas in any way of the transmitters within the phone is even more likely to cause damage, adding the foil changes the electrical characteristics of the antenna and what is called "SWR" (standing wave ratio).
When an antenna and feedline do not have matching impedances, some of the electrical energy cannot be transferred from the feedline to the antenna. Energy not transferred to the antenna is reflected back towards the transmitter. It is the interaction of these reflected waves with forward waves which causes standing wave patterns. Reflected power has three main implications in radio transmitters: Radio Frequency (RF) energy losses increase, distortion on transmitter due to reflected power from load and damage to the transmitter can occur.
So, mod your antennas at your peril.
Bending or cleaning the spring contacts that connect to the antennas will do no harm and could actually improve the connection but anything else comes with potential risks.
Steve.

I completely agree with the above statement this is dangerous and may also make your signal directional (so good for one direction - away from the foil side and terrible for all other possible directions) - trust me you dont wanna be the idiot standing in a room trying to "aim" your phone for good signal. Plus there is an agps fix available at http://forum.xda-developers.com/showthread.php?t=1442032 which is much safer and definitely works locks up to 13 satelites and atains lock in about 7 to 15 seconds for me. It further speed things up by eliminating SSL encryption when it gets the network time NTP to use for GPS location fixing. As for WiFi get a better router and maybe update the radio software both easy to do and explained in detail on XDA forums, and more likely to work.

Thanks for Your article. I didn't tap a foil, but i just scrached joints. It bring my gps to life

This is what i did please correct me if is wrong if alu folia can damage something?
After that tested gps, had 0 satelites before this and now
My router in room is about 2 meters far from my bed and chair and signal was like this now that signal is from outside 7 meters trough 3 thick walls
and inside is
Thanks guys

General Odd blanked out type of port on button side ???

So, got a 256 SD version yesterday, pretty soon noticed a type of blanked out port on the button side that i had not noticed on pics i had seen of the phone online.
Anyone know what it is and why it's not on 99% of the pics i see ??

This?
Probably has to do with the antenna.

No mate, can't you see my 2 images?
Its a 20x4mm section.

Mark it... that's why you got the big bad spen and screen write.
Likely an antenna.

It is a 5G mmwave band antenna

He probably means this, and i don't have that on my s22u at all. Others does have this?

That's an antenna I think. To verify watch a tear down vid of that model.
Makes you wonder if and if so how much it weakens the frame rail.

Yes after some google looks like some s22u has this and some others does not.
It is a cutout for 5g mmwave antena and probably yes, it could weaken the frame a bit or at least be a snapping point if the phone flexes too much. Just as antennas cutouts are.

It's one of the antennas. The 5G one.

Yer, sorry, i should have used my s-pen to circle it idd didn't think i needed to though as its fkn huge
So as I'm in the UK i understand i won't even be using it? :/ bummer!

Strange, I ordered mine from the German Samsung website and I don't see anything like this.

Mine is a SD version from US, so maybe that's it??

US models have mmwave 5g, other regions phones dont have. You can see it only US phones.

Has nothing to do with 5G from what I actually understand (not all 5G phones have this cutout, even US mmwave ones N20U for example). It actually has to do with Ultra-wideband which is used for precise location detection. Not Verizon's stupidly named UWB 5G. Something similar first appeared on the iPhone 11 I think, when Apple decided to launch their Airtags or whatever they are called.
It allows the phone to detect other equally equipped devices or tags or whatever comes along in the future with much greater accuracy than before. So say you have a tag on your keys, the phone will show exactly where they are (the couch for example) instead of something like "within 5ft of you".

Thanks for the explanation, but it is still strange that this cutout is not seen on every models. Are all S22U compatible with ultra-wideband? Mine has the option, but no cutout.

Samsung is like a box of rabid gerbils; there's no rhythm or reason sometimes for their bizarre behavior...

The N20/N20U didn't have the cutout but was able to do UWB stuff. Glass isn't the greatest for allowing signal through, so my guess is it's a way to allow better signal now that they have tags and such.
It *could* be mmwave 5G, but everything I've read points at an actual UWB antenna. Mainly because not all mmwave phones have the cutout, and reading into the iPhone when the cutout first appeared (they say it's for their tags).
But yes, like BlackHawk said, Samsung does mysterious things for the different regions. If the features you need work, then I wouldn't worry about it too much. I just find it annoying it's probably a weak point in the frame, but I've sat on my phone without a case and no issues so...
EDIT:
So I was looking at teardown images and that antenna actually says mmW on it. So it does have to do with mmwave. The fact not every mmwave phone has the cutout but this does still makes me think it's at least something to do with the fact glass isn't the best for signal strength and they decided to do things this way.

Makes you wonder if Samsung IDed it as a potential weak spot then modified it.
You get the impression Samsung is in a big, bad hurry.
Samsung's last solid flagship release remains the N10+ in my opinion. Its stood the test of time very well for a phone... it's a beast.
It's sad to see Samsung degrade their flagship line yet their midrange line still has expandable storage. This inverted marketing devalues their flagships... and they know better but like a brat they just do what they want. Then they make up lame excuses rather then owe up to their screwups. I don't see much hope in Samsung nowadays.
Samsung's latest Buds+ successor failed to impress me as a replacement. Not sealed and with half the battery life. The noise cancelling at this price point will not be optimum so it will likely degrade the sound quality noticeably. Worse the latest firmware update for the Buds+ degraded the audio quality. Do Not update the firmware if you have a pair of Buds+ as firmware they are shipped with sounds better*. The firmware is a pain to rollback too.
wtf Sammy, you nuts?
*I did an extensive side by side comparison... not my imagination! The old version is slightly higher decibel, brighter, with a noticeably better sound stage (that may not be the right term for a sealed bud but that's how it sounds)!
Got one pair of Buds+ that needs the firmware rolled back now because of this.
