Hey there guys, i currently have an issue with my recently purchased G2. Whenever i have the keyboard out holding vertically, i noticed my wifi signal started to decrease when i held at a certain position with my left hand. I usually have my left index finger resting on the side of the keyboard (top part of the phone), whenever i am holding it horizontally and i have noticed that the wifi drops considerable when doing so from 3 to 1, indicated by the wifi signal on the phone.
Any of you guys have the same problem? Try covering the top part of the phone or the left side of the phone if its held landscape (the area where t-mobile logo is) and tell me if your wifi strength decreases. Thanks guys!

Yes I have had issues with wifi whenever I cover the top part of the phone. Either when in landscape mode or hplding it to my head

I definitely see this. I don't even bother trying to play Pocket Legends on wifi.
I tried to google where the wifi antenna was, but gave up pretty quick - normally I have good "4g" coverage so I don't keep wifi turned on, even at home.
i dont think this phone even uses antenna's i opened up my phone before and there was nothing that looked like an antenna unless its inside the screen
My signal drops 1 bar by doing that as well. I assume its where the receiver is located

Easy on the death grip! also get a stronger wifi router, pref an N router. it'll help you.
it's not even that i have my whole hand plastered on the side of the phone, it is just my index finger that is giving me only 1 bar of wifi, even if it is lightly rested..
I kind of noticed this too last night. I was laying on my bed, and replying to a post in a local forum. I typed in my reply using the HW keyboard, then submitted. Then it failed. I noticed that I was not connected via WiFi anymore. I closed the keyboard and changed switched to a different position, then poof, WiFi came back on.
However, I don't completely blame HTC for this, since my Router's signal (WiFi-N too) is not that strong up in up in my bedroom. So I guess the antenna is located somewhere near there, and when signal is not that good, it drops. Not that big of an issue for me though.
Uh... keyboard out and holding it vertically.... why would you ever hold it like this?
I'm guessing he means horizontally. I get the wifi signal to drop when I hold it like this. There is a hole on same cases near the bottom left (when held normally keyboard out) that gets covered by my hand. This seems to be the location of the wifi antenna.
Sorry i mean horizontally haha. I guess this is a common problem not a unit problem. Is there any fix for this? I use wifi whenever im home or work since it is faster but i find myself clicking links and going to web pages without my left hand placed on the phone (held horizontally) in order for the page to load up fast.
I'd understand if i was covering it fully or if my fingers were firmly pressed against it but this thing is just too damn sensitive!!

Easy? The man can't hold his phone the way it was intended?
While this is an amazing phone, I'm regretting to learn that the radio equipment is pretty ****ty. It's such a disappointment. I have a top of the line router and live near a cell tower and still get poor reception. All my electronics are RF shielded and I live in a new home with little wireless noise. I know a thing or two about troubleshooting wireless challenges and I am absolutely positive that it's the radio hardware.
I've had friends bring over their devices, one being a DZ and it also performed poorly. Hoping that there's something software related that can be updated by HTC to fix this. Chances are slim though... thankfully I switch out phones every 4-6 months. Love my DZ other than this major flaw.
When I hold my DZ horizontally with keyboard open I either have all wifi bars or 1 less sometimes but it still works very well.
I had indeed to have a look at the icon when I read this thread to notice that I could lose 1 bar sometmes as I have never noticed any problem with wifi.
I have tried different ways of holding the phone and even when I try to cover wifi antenna location I don't always succeed in getting less bars.
Could it have to do with the fact that I'm a girl and have smaller hands so cover a smaller surface of the device?
I've posted a video on the problem.
I'm quite surprised that there is no other thread on this after realizing the number of people that have the same problem. I want to know if this is a problem for all users or only for certain defective G2s, so I know if should send it in.

That could probably be the cause.
I was able to replicate the issue again, but now with better WiFi coverage. So yeah, I noticed that my signal bars drop 1 to 2 bars when using the HW keyboard, and it immediately pops back up to full strength when held in a portrait position. However, the AP that I was connected to was a G one, I think.
As for me, this isn't quite of a major issue for me yet. I only use the HW keyboard when doing SMS and typing in long info while browsing. Though it can be a pain when doing instant messaging on the phone.
I don't think the type of router is the cause, i think its just poorly placed and sensitivity of the wifi antenna. I tested it out on my university wifi and same result. The engineers failed on this one!
I noticed a drop of radio signal when using the hardware keyboard of my G1 (HTC Dream). IMHO there is nothing like a perfect place for a radio or an antenna in a smartphone. See the discussion going on regarding the signal drop of the iPhone 4, same thing. Every human being has different hands and holds a phone in another way, maybe similar but still different. There is no standardized hand, you know?
Just my opinion. :]
I purchased a Netgear WNDR3700 and set it up using both stock firmware and DDWRT customer firmware and did extensive testing, not just for G2/Desire Z testing but for my other wireless devices as well. I can assure you that the radio hardware and antenna placement/design are really lacking.
I've found that with my new wireless connection there is far more stability as I've never optimized my old router (Linksys WRT610 with DDWRT FW), but a definite loss in signal from the way the device is held. It really sucks, but it's not at bad as the mobile connection. I always have just a couple bars and then 0 bars, then it begins bandswitching and sucking some hardcore ****.
I really love the Desire Z otherwise but it looks like I need to hold out for the Motorola Atrix or the dual core LG Optimus coming out soon.
Me too
I see this drop in reception too, and sometimes a drop in 3G reception when I hold it certain ways. A bummer, but pretty much par for the course. I've never met a phone that doesn't suffer this same problem one way or another.
I just live with it. It's still a great device.
has anyone opened a bug ticket on HTC's site?
I noticed two things about the NFC reader on the N7
1) It only reads from the back of the device
2) It only reads when another device/RFID is about 1cm away or less
Is the NFC sensor movable/power adjustable? I want to move it to the front of the device, but also be able to read other devices from a farther distance (5cm?)
The idea is that tablet is embedded in a kiosk, people walk up to it and tap their NFC directly to the screen to interact
Not really. The antenna isn't very powerful. I tried using my NFC tags on the front but it would not work. I guess they assumed that you would be tapping the device onto the tag.
Sent from my Nexus 7 using xda premium
Perhaps a workaround...design a mount with a small opening behind the tablet, where people can "slide" their other nfc-enabled device back there to read
Hi, anyone of you using NFC tags?
I bought some and don't know if they are working correctly...
My tags are only found when they touch the back glass - when there is a little spacing they don't work! Whey I use the plastic phone protection (less than 1mm thick) the tags are not detected any more! (maybe once in 100 attempts)
What distance do you reach?
Is there a possibility to increase the range?
What part of the back are you touching? The antenna is right between the LG and the Nexus. http://guide-images.ifixit.net/igi/yapggXkL1qUdlt3J.huge (The black sticker)
It works fine with my dixtronic. That covers the glass too.
I believe NFC has a maximum working distance of 1.5 inches.
AW: NFC distance
1.5 inch are about 3.5 cm - I don't even get 0.3 cm!
It is independant of where I put the tag - believe me, I tried it everywhere on the phone...
So you manage distances of several cm? Then I must have bought bad tags...
AW: NFC distance
Once more:
- What tags are you using?
- What distance between Nexus 4 and tags is (really) possible?
I'm having this same issue and this thread came up in Search so I thought I'd revive it instead of making my own thread.
I am using two different NFC stickers as my test. One is actually stuck to my desk at work, the other is still on the wax paper it came on. I can only get the movable sticker to read, and that's only when I touch it to the back of my Nexus and slide it down. Once it reads, I set it down on my desk to act like it's stuck (in case the one that is stuck there is bad) and I can't get it to read. I even set the phone down on it, nothing. I hover a millimeter above the desk and slide it down the phone and I get nothing. When I lift it back up and touch it to the back and slide like before, it reads. Why is my range SO small? How is it not reading the stickers when they're horizontal on my desk? If it matters at all, I bought the stickers from the people who made NFC Task Launcher app.
Well - to be honest, I do not use them anymore...
BUT: If you try "NTAG203 168 Byte" or "NXP Mifare Classic 1K" or "NXP Mifare Ultralight C 192 Byte" (the best one) you can reach far more distances (up to ~2cm) - then it works though the Phone-Cover and some mm more plastic without any problems.
Ok I did more messing around and found out what was wrong, I'll post in case anyone in the future finds this thread.
After doing more experiments, I found that I could lift the phone up, and lift the sticker up and it would read the sticker from a distance of around 2-3cm. I tried doing it horizontally and vertically, in case for some random reason, my phone's NFC wouldn't read horizontally. It worked when off the desk, but as soon as I set the sticker back down and tried to read it, nothing. After pondering for a bit, it hit me. My desk is basically all metal. I didn't really think of it because most of what I see is "wood", but upon further investigating I found out it's just a thin covering of some material that looks like wood on a full-metal desk. After 1 Google search, I find out that metal can interfere with NFC signal, which is why I couldn't pick up my tags on the desk.
Sure enough, put the tags on a small stack of sticky-notes and my phone read it from about 3cm above the tag. Problem solved. Man, that was frustrating. I was worried that my phone's NFC sensor was defective or something. I wasn't about to RMA and wait for weeks to get my phone back, I'd miss the thing too much so I'd just live with it. Well, that's not the case so great. Hopefully this helps someone in the future.

I've tried tried on a wireless payment card and my N4 can read it through 5mm of paper, any more than that it can't find it.
The problem may be with your tags, do you have anything else you can test it with like a wireless credit card or transport card?
...by 'proper', I mean 'standalone'!
Basically the same as my old Vapirius AX (similar to Rock/Z1) that I've used daily for 2 years, but much cheaper and runs Android 4.1 and it has 320x240 2'' screen and not the square 240x240 1.5'' style of most watches which I can't get on with.
I'm going to order it and check it out. .
Nothing to lose at that price!

Wearable Smart Phone Watch AN1 2.0" Touch Screen Android 4.1.1 w/ Camera / Wi-Fi - White + Silver - Free Shipping - DealExtreme
Looks like the Neptune Pine...
The AN1 Reviewed (I Think Comprehensively)
Here's what you need to know about the watch, which I've used for several days. It's more a sweet novelty than a gadget of genuine use. But it works. It's basically a mini-tablet phone (or phablet) and functions via the exact same Android protocols, except the master controls are hard, physical buttons built into the left and right sides, rather than soft touch-buttons on or below the screen. And of course the interface is configured to adapt to the tiny size. Yet at two-inches, that screen is a bit big for comfort if you like wearing the watch face on the inside of your wrist (which I do). So I sometimes rotate it to switch position.
Touch sensitivity seems excellent, as well as touch accuracy, which is hugely important given the minuscule QWERTY keyboard that pops up when you need to enter text. Unlocking the startup screen is frustrating at first until you figure out that you have to swipe the icon up or down, not to the side, as on bigger screens. There's no icon or hard control to access the active-apps screen (from which you can toggle back and forth between active apps and turn running apps off); as on certain larger phablets, you get to it by long-pressing the home screen button.
Because the AN1 is small, its WiFi receptivity is modest (the signal is strongest the closer you are to the source). So's volume but it's not bad for the size. You won't hear much through the earphones except in relatively quiet places, unless you have a separate sound booster; but in quiet places it isn't bad. However, it's impossible to attach the earphones one-handed; at least it is for me: You have to hold open the protective soft plastic flap that covers the mini-USB port (which is where they attach), which means you can't wear it while setting that up. That said, the AN1 will also transmit to Bluetooth headsets. And video/audio playback is very smooth. Even impressive, all things considered. Not a gamester, so no idea how gameplay would go. But with a two-inch screen, why would you want to?
Believe it or not, eBook reading is also a very decent experience in either the page or landscape aspect, though for simple eye-to-text positioning, page view works best if you take the watch off and operate it two-handed. In landscape view, though, you can make like **** Tracy. The only reading app I've tried so far is Amazon Kindle, but every feature seems to work per normal. Whatever normal is at that size.
No problem with the phone detecting a SIM card or storage-expansion microSD card (I added the 32G max, which costs all of $10 on eBay). But the cards are tricky to insert, because the lock flaps that secure them in place are so flimsy. However, once they're in, they're in. And insertion of the expansion card is critical, since the Internal Storage provided is write-protected; you won't be able to download (via internet) or sideload (via computer) files or apps without providing extra storage.
The battery is built into the back cover. Comes the time when it no longer holds a charge, one would need a replacement cover. I assume those are available or will be made so eventually.
There's no Playstore app included; plus it's futile to sideload-and-install Playstore from another source, since the app quits as soon as it boots. There is instead the HiMarket app, whose store features mostly Chinese text; but if you know the apps you want/need, you can still enter a search in English and find them -- most of the time. Sideloading and installing other apps also seems to work -- most of the time.
And oh, yeah -- in the "Good safety tip, Egon" department -- don't wear the AN1 (or any other Android watch of similar concept) in inclement weather. With an exposed speaker grille and exposed miniUSB access port (the protective flap doesn't fit snugly), not to mention hard buttons that aren't part of the case proper, bringing this out into very moist air or, worse, active precipitation, would be like putting your iPad in a filling toilet tank to see how high the water has to go before it fries.
Not encountering anything much in the way of buggyness yet. All in all, the AN1 does precisely what it claims to do. And for the conversation-pieceness of it, and frankly, the satisfaction of my curiosity, I'm happy to be an owner. It won't collect dust. But it's not for the customer looking for significant enhancement of his electronic life beyond what he already has.
Thanks for the review.
Also been using the AN1 for a couple of weeks and fairly impressed, but then I've been wearing a similar one for a couple of years and have only that and a conventional phone to compare it with.
Confused what you say about the battery; my AN1 has a battery on the back that can be detached and changed by pressing a small recessed lug/clip. The battery is the same as the old Z1/Rock/Vapirius so is readily available. Are you sure your battery is non-removable?
Also, as it's rooted - although Superuser is not installed - all current Play Store and Google services, sync adapters etc can be side loaded into system/apps, changing permissions the usual way. I am running all the latest Google App stuff now, but you're right about the Chinese Market and I removed it immediately along with anything Baidu related.
My only mild criticism of the watch (I can live with the floppy USB port cover as most mobile phones have no cover whatsoever) is the screen, not the digitizer which as you point out is responsive and works well, but the outside screen. It's scratched badly already and cleaning it makes it even worse. It's almost like a bad plastic. My other smartwatch has been used every day for two years and the screen still looks brand new without protection.
Lesson is get a good screen protector BEFORE even touching it! Although is fairness, the scratches don't really show when the screen is powered.
The sound can be tweaked in the engineering settings (I've forgotten the number/symbol sequence to access those settings right now) and I have managed to get it sufficiently loud to annoy other people listening to a phone conversation.

This isn't a Play Store compatible device. Also, looking at the pictures, the apps are proprietary.
Some Android devices, especially Chinese ones that I've used, Google Services aren't installed and have been done so manually in order to get all the Android features.
This isn't one of them.
I can give the firmware for the AN1 if someone would like to make a custom rom.

All those sensors are useless if there's no app for it.

They've caught on to a great idea, but it seems pretty pointless as said before. Hopefully there will be some improvements in the (less expensive) range of android wear.

Details on how to load all the Google stuff onto the AN1 and most other similar Chinese devices are here (reply#7):
http://linuxslate.com/cgi-bin/forum/YaBB.pl?num=1399895851
These are the steps:
Here are my instructions for putting all the correct Google Play stuff and thereby having a full non-Chinese Android. Remember to totally uninstall all the Chinese Market and Baidu.
Download the files from here:
https://www.dropbox.com/sh/56ppcal1t9dwm6g/AACubjVgwQIcFjVv0_wvo05na
1. Use Root Explorer
2. Copy GoogleServicesFramework.apk, GoogleLoginService.apk and Google_Play-v3.8.17.apk to the system/app folder on your phone with Root Explorer.
3. In Root Explorer click Mount R/W. Change the permissions of the 3 files to match the permissions of the other files in the folder rw-r--r-- (6-4-4). Then click Mount R/O and exit Root Explorer.
4. Install GoogleCalendarSyncAdapter and GoogleContactsSyncAdapter the usual app way.
5. Reboot your phone. Hard reset is not necessary.
6. Go to Accounts & Sync in your phone's settings, click Add account and enter your Google/GMail account details.
7. Go to your apps and Launch Google Play.
8. Update any Google stuff from Play Store if prompted.
I'll do a vid of this sometime.
Good luck!

AN1 Battery Clarification
Hey, Marcus -
Sorry to take so long to reply.
When I said the AN1 battery was non-removable, I meant that the back of the AN1 watch IS the battery, for all intents and purposes, and is the battery housing, not a mini-case into which a battery could fit. Yes, as you say, it's removable via the lug-clip and that gives you access to the card slots. But I didn't know one could buy a replacement; the lug-clip architecture is so specific to the watch build that I thought an AN1 battery replacement would have to be sold as a locked-to-the-model accessory. (Well, until today; trolling around eBay I saw a Z1 battery/back panel replacement for sale and kind of assumed it would fit the AN1. But it was $39 which struck me as high, so I didn't purchase. I'll do a broader search for Z1 replacements now, though. If you know of where they can be gotten cheaply, chime in.)
No Real Need for Rooting
By the way ...
Even though the AN1 isn't Play Store compatible, I've been able to load everything on it that I need. I either find direct links to download the APKs desired, or APK store links that bring me to the APK. In any event, sideloading from my computer is easy, then I just use File Manager to open the apps. If the apps don't work, I uninstall them. Most of them do. And there are so many choices that you can eventually have it doing everything you desire of it. (Beasr in mind, it's not really practical to install anything too unique or fancy on the watch because of its screen size; it's best for basic utilities that let you play videos, read books, manage calendar data, email, facebook, etc. And it does all that handily. Sometimes not with apps that work on your larger Android devices; but it doesn't take much time at all to find something that'll do the job as well in miniature.)
I have a nexus 7 and a nexus 4: My wife has another nexus 7
I have been using nfc on very few ocassions, but it's comfortable when my wife wants to send me a link and we are just in the same place, instead of pushbullet, i used to use NFC: Put the devices back to back and receive the link.
For some time, my device has been in the hands of a repair technician because I had a fatal drop that ended my nexus 4 screen a while ago. Long story short: LG kept sending defective pieces and everytime I got the phone back, I'd find something not working: Battery damaged, Screen doing weird colors, proximity sensor not working.... not joking.. a lot of problems: But now it seems fixed for good - i even got the back cover replaced, where, i think, the NFC chip is located.
Now, lately, I've playing around with some new AOSP 5.0 images: First, with an unofficial CM12 ROM.
After the first boot, you get the option to transfer your data from another nfc enabled device to your device, so I put my nexus 7 (with cyanogenmod 4.4.4) back to back with the nexus 4: Nothing happened: "Well, maybe because it's a new system, NFC is not working".... then I kept on playing with the rom, not really concerned about NFC.
Some days later, I shifted my Nexus 7 to SimpleAOSP 5.0 and afterwards, did the same with the nexus 4: Again, NFC did not work between both devices upon the nexus 4 first boot: Something's wrong.
I opened the device and the NFC chip seems to be there. Hardware-wise, at first look, everything seems to be on it's place: I even flashed the latest radio image from the official image downloaded from google: Still no luck
I tested reading my gym's card: It's nfc enabled and my nexus 7 reacts to it: You just install a reading app and can see what's on the card. However, the nexus 4 does not react at all.
I don't know what else to do and finally, gave the NFC capabilities for lost. Anyway, no biggie: I don't really need them.
But today, at my job, I decided to try something: I have an unofficial wireless charger. I thought those worked with NFC so, to my surprise, when I put the device on the charger base, it got detected and it's actually currently charging beside me while I write this....
What's going on? Or perhaps I'm wrong and wireless charging is not related to NFC at all?
Please help.
NFC and wireless charging isn't related, there's 2 coils on back of phone - one for NFC and other for wireless charging - check connection of those 4 pads : http://www.parts4repair.com/nfc-wireless-charging-coil-for-lg-nexus-4-e960/ , looks like nfc part isn't working ...
Ok, so what you linked is the wireless charging receptor?
Can you point on some image which exactly are the nfc antenna is so I can review them and see if they make contact successfully? Or you mean the same "pad" on the back has both antennas?
Thanks!
here you can see 2 coils - one for nfc, other for charging http://cdn2.bigcommerce.com/server5...ntenna_02__02990.1411006050.1280.1280.jpg?c=2
So, If one of them is not working, i have to change the whole thing... right?
yes, but first check coils resistance with multimeter and double check connection from mainboard to this nfc/charging receiver pads .

This is beyond my knowledge: I'll try the old cover with the working nfc and if it works, switch the coil from the old back to the new one.... my insurance really messed up this time: I have been more than 9 months trying to fix the phone. Originally it war a broken screen... they fix one thing: Break two and the worst thing is that it usually takes me some weeks to notice, so finally, maybe they'll think I'm trying to scam them or something..... it really drives me mad.
Thank you.
