[Q] Death grip

Hi everyone
I have this problem:
http://www.youtube.com/watch?v=2Gu9oKlWq1Y
Anyone know how to solve this problem ?

Just as a disclaimer, every phone will lose signal if you grip it a certain way. Remember the iphone debacle?
But the quick fix is to just put a case on it. Your body will no longer interfere with the antenna and your phone will have the added bonus of surviving a fall.

Downside is cases tarnish the natural beauty of the phone that the cell phone manufacturers intended. I just take the risk. I would rather have a nice looking phone IMHO.

I already have this one http://www.otterbox.com/HTC-G2-/-HT...C4-G2XXX_color=20&start=1&cgid=desire-z-cases

gripping ANY phone tightly/awkwardly over the antenna will cause loss of signal. Some are worse than others, but it happens to any modern phone with an internal antenna. Cases help, but you're still going to be able to replicate it if you try hard enough. The phones are designed so that the antenna will more than likely not be blocked if you're holding it in any normal conventional way during regular use.
One usual culprit for the G2/DZ is the WiFi signal getting weaker when using the hardware keyboard, because your hands are covering the top and bottom of the device.

so isn't any idea to solve or help a little with this problem ?

Like I just said, there's nothing you can do other than just don't hold the phone in such a ridiculous way. You can't move the antenna inside the phone, it is where it is.
In normal use I highly doubt you'll ever see drastic signal drop because of the way you hold your phone. Nobody normally holds a phone in the way shown in the video.

So tell me how to play in gameloft games where all of them is in landscape mode

like I said, using the phone normally (yes even playing games in landscape) your signal shouldn't drop so low that you will be completely disconnected from the network. Don't get scared just because the bars drop.

But i already play at Order and Chaos and this game are also in landscape mode and unhappily i get lost connection every few minutes ;/ and the game has reconnecting.

There's nothing I can tell you. The antenna is where it is. If for some reason you're in a low signal area to start and you cover the antenna you're going to see loss of signal.

Tell me if i give back this mobile on warranty then they are able to solve issue ?

You're not listening. Every phone has this issue if you hold it in the right place. Its a cell phone with an antenna. Its just going to happen, there's nothing you or the manufacturer can do to "fix" it after the phone has been made.

I acutally thought this was a radio problem. I switched radios and noticed a slight improvement.

A radio update can help your signal a bit overall, but it will never remove the effect of strategically covering the physical antenna. What it would help with is a default low signal, that gets worsened to the point of disconnection from the network by covering the antenna (aka your normal signal could be higher, so that when it gets lessened it still stays connected).

[Q] No phone signal with internal antenna

Hi everyone, I got my phone about 3 weeks ago and worked well (rooted it, then flashed it with a rooted Brazillian rom) till 2 days back, I forgot to register the IMEI with my service provider (using a company phone number) and got my incoming and outgoing calls blocked, but I was still able to use data connection. I didnt give it much importance since I work out country and the nearest office is 3 hours away.
I was able to call using another SIM card (personal phone number) and register the IMEI with my other provider. Couple of hours after that, my signal went dead, I then tried several SIM cards and still no luck. Messing around afterwork, I connected the external antenna to the phone, and I got signal back! I left it on all night on my desk. Next morning came back, disconnected and lost signal again.
My companies SIM card is working well on other phones. The only problem I have is that I need the external antenna connected to get signal.
Has this happen to onyone else? Ive searched several forums with no luck.
--------------------------------
I did some testing and went to the cell tower thats in our camp and got a good signal.
Seems that my internel antenna is messed up or something is not right with the radio.
I dont want to open it until I go back to the city. Anyone knows how to check with an app or something?

Found out what caused my problem and gave it a very simple solution. (http://forum.xda-developers.com/showthread.php?t=1273292)
The problem was that I plugged an external antenna that was a bit more thicker and ruined the internal contact that the internal antenna uses.
The solution was cutting a thin copper wire to 16.6cm long, plugging one end to the middle of the external antenna socket and folding the wire around the battery so it would touch it. Signal didnt go back to 100% but worked at about 90%.

Same problem here! I use a wire connect to external antenna too.
There is any solution for a internal antenna back to work again??
Its seems as a very bad design error

Signal problem after drop

Drop my Note 2 this morning and since then, the (GSM/LTE) signal seems unstable. Most of the time there's just no signal at all, a big O in status bar. Sometimes I manage to get signal by pulling out battery and knocking around the phone (!!), then after a while it gets back to no signal. What could be the problem? Did the drop this morning damage the GSM antenna? If that the case, where is the GSM antenna in this phone? I might want to open it up and check tonight when I get home.
PS: Check with other guys in the same building with AT&T, they seems to be fine regarding signal, so probably it is just my phone's problem.

Re-seat your sim card. Squeeze the antenna module.
Maybe open it up and check the internal connector.

That's the plan. Just not sure where is the antenna module though

GPS Dropping

Does anyone else have this issue? My GPS loses connection to the satellites every couple minutes. And yes, I have the latest map update.

Must be the bug in update. Try to use 3rd party app! Just because i never updated mine, and is working like a charm

The GPS in my phone is not very accurate. Maybe its just this phone. I only get relatively good GPS reception at night.

Thanks guys. I'm starting to think it may just be this phone as well. The first map told me I was 3 miles away from my house....lol...and the second was accurate but keeps dropping the signal. I do have carhome. I'll try that and see what happens.

I also have this issue though the GPS (which is used a lot by me) was quite OK in the beginning after I bought my LG OG PRO.
I read in one of the Samsung NOTE forums that people mention the same problem claiming that the drops come when there is an "interruption" (which can be an incoming call or SMS or switching from 3G antenna to 3.5G for example). After reading this I realized that my GPS gets lost always after an incoming call plus I see at least a couple of places along my daily driving routine where GPS is lost exactly at the same place every day (making antenna switch assumption logical).
There were no any conclusions or suggested solutions in these forums, people even do not know if it is software or hardware related.
Anyone has such an issue too? Any recommendations for possible fix?

I can't believe but it seems I solved the problem with GPS - 15-20 seconds for GPS lock, no dropping and GPS test application shows very nice picture of 8-9 satellites constantly locked up while most of the signal bars are yellow (i.e. the signal strength is good).
I searched a lot as it really bothered me because I use my GPS very much plus I can say that beside this annoying thing I am very satisfied with my LG OG Pro, but nothing helped until I found this video: https://www.youtube.com/watch?v=QBpNtWvY454 (it explains the solution for Nexus 5, but my problem is identical)
Basically, the problem is that there are special contacts on the motherboard connected to the GPS antenna which is part of the back cover and the contacts are not tightened well to the GPS antenna (look at the attached picture where I put the red arrows at the relevant places). Due to the bad touch between the contacts and the antenna, the GPS does not work properly. So, all you need to do is to remove your back cover, gently "un-glue" the GPS antenna end (the rectangle part on the back cover containing 2 golden dots), lift it up a little and put a piece of paper that will tighten the antenna and mother board contacts when the back cover is returned. Good luck.

It is NFC Antenna, you cant fix GPS this way.
I have same issue, but i think NFC and GPS antennas are different. I am disassemble the phone and pull up all golden springs - but gps still very weak(((
Any solution?

same GPS problem for my g pro.
GPS is weaker and weaker

I realigned all the pins inside the phone and fixed it for a bit, but the signal was still weak. I figured it was the modem. I installed a custom rom and it worked like a charm!

Note 2 N7105 not registering on network

Shouting out for any help.
I've got a Samsung Galaxy note 2 N7105.
About 9 months ago I replaced the motherboard with a secondhand board from a broken phone and all was good.
Last month I decided to listen to some music using headphones and it was very crackly, but improved if I squeezed the phone case.
Quick check on google and apparently its a common problem , so dismantled the phone (again) and cleaned everything up. Put it all back together and hey presto ! .. Audio was working fine... BUT then I noticed that I had no mobile signal.
Without a sim installed I have 3 or 4 bars, although I have no idea what network its getting that from !... When I put the sim back in, the bars disappear and I get the not registered on network error message.
I've tried automatic network selection and manual but it makes no difference.
I've dismantled the phone and made sure all the sockets and wires are where they should be but still cant get a mobile signal with a sim in.
Wifi works fine.
Any thoughts (apart from throw it away !).
Thanks in advance.

You could try to replace the SIM/SD card reader.
I recently replaced the mainboard on a Note 2 GT7105 only to be confronted with SIM card problems on that mainboard. It would not register my SIM card.
I have paid around 10€ including shipping for a new SIM/SD card reader and have now a working phone. Replacement is straight forward, look it up on youtube!
For the audio...I have exactly the same problem, cracking/distortion when using the headset...speaker is normal. I have tried all the suggestions I could find on google and have come to the conclusion it is a bad contact in the connector between the mainboard and headphone jack. To be more precise, the problem is on the mainboard side on my note as I replaced the headphone jack module...I have given up since. Really disappointed as I had invested in a new frame chassis and almost new display. I will use this phone as my GPS, this phone has a GPS fix within 10sec in my house! Never seen such a powerful GPS in a phone...

Have you checked your imei ?
Also, check network anntena cable properly locked in.
