Serious antenna problem!
With the external antenna a lot of people are having signal issues. If you hold the phone in a way that, your hand covers or touches all three sections of the band, the signal just falls almost instantly. It's terrible and probably the reason for the bumpers.
I mean, why would you really need to protect stainless steel!?
I have a cell tower literally yards away from my house and can destroy all 5 bars by holding it a certain way.
Is everyone having this problem!?

Obviously this IS a widespread issue. Apple SHOULD respond and acknowledge it. And it's not something where people SHOULD have to buy a case simply to use their device.

Lumia series and antenna problems - true?
Hello
Just found a very odd recently made study of mobile phones antenna performance. It seems to be serious science, but the results are most definitely not in Lumia's favor. Actually Lumia 925 is rated as the phone with the worst results - which seems ludicrous to me. It's the first I've heard of antenna problems with the series. Can anyone confirm or deny problems with the antenna on recent Lumia models? What are your experiences?
http://erhvervsstyrelsen.dk/file/435579/Mobile_Phone_Antenna_Performance_2013.pdfIt is normal for the signal bars on the phone to fluctuate as it jumps between different cell towers, and both the cell towers and the phone adjust their transmit power all the time. Different phones have different behaviour of the signal indicator. The actual antenna performance can only be measured in a controlled environment, like the nerds from Aalborg University do in the PDF link in the first post.
In real life the antenna performance of my Lumia 720 is on par with my N8. In poor coverage they both give up in the same places. The behaviour selecting 2G or 3G is different though, since the N8 favour 2G when talking while walking or driving, where the Lumia always want to hang on to 3G whenever possible.
Regarding the Aalborg University antenna test, these people are independent and serious about what they do.
Please read the whole PDF, so you'll see that the poor performance is only when held in a phantom hand towards a phantom head, in the right hand, as seen in the cover picture, and that it mainly affects the GSM900 (2G) frequency band, on the devices tested at the time.

Serious performance problems on iWeb site
Can anyone help me find the problem with peterlance.com? It looks like author Peter Lance uses iWeb to update his web site. He redesigned it recently (and did not use iWeb for the old design). Anyway, it has serious performance problems on Internet Explorer, which I was hoping you guys could help pinpoint? Is there something simple I can tell him to try to fix the problem? He is launching a new book on Tuesday so he will be getting a lot of traffic, but for now the response time is not very good. Any suggestions?
In particular, each new page seems to hang for about ten seconds and freeze using Internet Explorer 6. Any fixes?
I mean, fixes other than: "Don't use Internet Explorer!"

name="Generator" content="iWeb 1.1.2"Welcome to the discussions, TopDog08.
There are several plain .jpg's and that's good, but you need to convert every .png on the page (or as many .png's as you can) to a .jpg. For example,
http://www.peterlance.com/Peter%20Lance/Home/Homefiles/shapeimage46.png
Convert that to a jpg, then replace the graphic and text on the iWeb page with this converted jpg (some have has success using Downsize http://www.stuntsoftware.com/Downsize/)
The ones you won't be able to do anything about are the ones that are a part of the blog, but that will be only 5 images instead of the many you have now.
This image
http://www.peterlance.com/Peter%20Lance/Home/Homefiles/shapeimage50.png
Is covering part of your menu which is why it appears that only the top half is sensitive to rolling over. You'll have to adjust your layout to account for this.
Another area to look at, there are white boxed png's surrounding the amazon book covers at the top.
http://www.peterlance.com/Peter%20Lance/Home/Homefiles/imageEffectsAboveAli%20Mug%20TPI%20jpg.png
Another set of .png's you'll have to get rid of. How did those get put on the page?
What you see happening with IE is a java script running to fix IE's problem with png's. The fewer .png's you have, the less of a problem with IE you have. -
Serious performance problems after updating from 10.5.6 to 10.5.7
I've got a Macbook Pro C2D 15" (late 2006). After updating the system from 10.5.6 to 10.5.7 and quicktime to 7.6.2, I experience serious performance problems which I have never seen before:
-From time to time, kernel_task has peaks in activity monitor (consumes a lot of CPU). In that moment, the mouse hangs for a short moment and audio playback is distorted/has drop outs.
-Recording audio consumes a lot of CPU (independent of the audio application).
-Video playback consumes a lot of CPU, regardless if I use VLC or the quicktime player.
Any idea what could be done? Thanks in advance.After a few days of using CoolBook I report that my 1st generation MacBook Air is now reliable and never overheating, regardless of environment conditions.
I must point out that I do believe that it really is something new in 10.5.7 that is causing this problem as my environmental conditions have not changed and even Summer in Dublin still sees temperatures no more than 72F/22C. I am now in Madrid, where the environment is quite different, and I am still having no problem with kernel_task spinning.
I plan on reporting my problem to Apple anyway and being aggressive about the issue as MacLovinRanga did in this thread (http://discussions.apple.com/thread.jspa?messageID=9647353#9647353). Perhaps many/all of those of us having this problem will obtain new MacBook Airs.

Hi
I am having some very serious performance problems witgh java web start. I have a swing client that transmits XML/HTTP to and from a server, parses it, etc... I am finding that the XML/HTTP data request
is a factor of 10 to 100X slower, at least, using Java Web Start than without.
Any suggestions would be helpful
Thanks
CharlesCharles,
I've also observed some overhead when running an application deployed with JAWS compared to running the application from the jar, or in my dev environment.
After searching these forums a bit, I found this buried nugget of info: Try System.setSecurityManager(null) if you are requesting <all-permissions/> already.
Before the workaround, my application was taking 194 seconds for a single analysis run. After this workaround was applied, the same analysis run took only 82 seconds.
So as you can see, there is considerable overhead associated with performing operations through the layers of security (my guess). My particular application does a lot of disk I/O (which is probably something the security manager watches closely).
I stress the 'workaround' aspect of this because I haven't fully investigated the ramifications of using it, but eventually this might turn into a bug submission (because if I'm already requesting all-permissions, why do I still need to do setSecurityManager(null)?).
At any rate, hope this helps!

My brother is havign some serious iPod problems. A while ago the battery died after having it for about 2 years. He just had the battery replaced, it will atleast bootup now, but it wont get passed the Apple logo. I can get it to boot into Disk Mode, then reset it, but it still wont get passed the Apple logo. Does anyone have any idea what's happened to it?
Thanks in advance!
MattHi Jeff, thanks for the response, i have been able to do that a bunch of times today, i've even opened up the Disk utility and erased and then done it, no such luck, it just wont get passed the apple screen

I have been speaking to Old Toad for the majority of today trying to fix my iPhoto Library as its become corrupt and I cannot get my photos/videos back into iPhoto. After many many suggestions I seem to have created some serious system problems.
PLEASE READ ALL OF THIS THREAD...
https://discussions.apple.com/message/21742033#21742033
If anybody can be of assisatance that would be a great help.
I am a mac dummie, recently transfered so foolproof guidance will be helpfull!
(Unfortunatly.. and now I know the importance, I haven't used time-machine and my mac isn't backed up. If i restore to factory settings I will loose the 600+ photos and videos I had in my iPhoto Library.... which dissapeared, which is the whole reason why I created the first thread)
Thank you!!Linc:
It appeared to me that somehow the OP's Picture folder was converted into an iPhoto Library as his screenshot of the PIctures folder looked like the inside of a library.
This statement by the OP make me think it might be more than just an iPhoto issue (the bold text):
I am unable to drag the Picture folder to the desktop, It wont move, and iPhoto (which is still empty) just opens.
Some how the same is happening with Documents,

Serious display problem. Please help!
I'm having a serious display problem all of a sudden. It is not application specific. Various different applications are pixelating, especially wherever I move my cursor and click the mouse. When I grab the entire application with the cursor and move it, the image duplicates into hundreds of images all over my screen. If I shake it around awhile, eventually it goes back to normal. What is going on??!!
Here's some background info: I'm on a 2009 Mac Pro. I still use the old fashioned tube monitors with mini display port to VGA converters, but I've never had a problem up until now. Just before the problem started happening, I tried to open up some .jpg files in Quicktime Pro 7.
I would greatly appreciate any ideas of what the problem could be and how to fix it.Welcome to Apple Discussions!
Might you have moved the Home folder or its contents, or renamed it? If you think that's what happened, this article may help:

sir since update of ios 8.1.2 i got serious battery problem on 3g 4.30 hrs my battery gets low and sometimes serious net probelms please give an update for this issue its not alone me my friends too getting many problem commonly battery problem please can this be resolved
its not related to any hardware because last year april i got replacement new phone from apple and i maintained it well...!Probably apps running in the background are causing this, sometimes Mail get's stuck connecting to the mail server, or some social media app like Facebook can also be a reason for prolonged background activity.
Try to reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again. You will not lose any data by resetting, but it can cure some glitches.
If this does not help, setting it up as new device would be the next step:

Has the antenna problem been sorted yet?
I'm a left-handed fellow, and I am having to upgrade from the 3g to the 4 because the 3g has just become unusable with iOS4 on it. I can't get iOS3 on my 3g which I am a bit annoyed about (or at least I don't think I can because I lost my iOS3 backups)!
Anyway, has the antenna problem for left-handed people been sorted out now? I hope so cos it'll annoy me that I have to buy a new phone that doesn't work properly just because the one I have did work, but now struggles to do so because of an OS upgrade I didn't want!
Thanks.
Matall phones are bound to have reception problems if you are in a area that gives you weak signals, and by holding on the death grip area. But if you live in a area with very strong signals, even if you hold it by the death grip, you should not lose the reception as it has no effect.
Just avoid holding where the black lines are, then you should be fine. If not then use a case. They do have a free case going on until sept. 30th. -
My ipad 2 is experiencing an antenna problem. Can this be fixed and is it financially reasonable to fix it?
SummerGirl02-
Were these pictures placed in the DCIM folder by the camera, or did you copy them there from your computer? I read somewhere that the pictures have to have names like the ones the camera makes. Names like IMG_0521.JPG (Canon), DSC01760.JPG (Sony), or IMGP0021.JPG (Pentax). You will notice they all have eight character names.
If that is not your problem, it could be that the Camera Connection Kit draws more current from the iPad than is allowed. A previous update to the iOS lowered the allowed current, causing some problems. Try updating to the latest iOS 4.3.3, and see if that makes a difference.

Iphone 4 antenna problem not so fix
ok so you guys fix the problem with the iphone 4 bumper case , the problem is that my iphone 4 cost too much money to put it in a case that doesn't protect that much , i have my iphone 4 in a really protective case , and i have problems with the antenna , not to much , but i have them , so i suggest to make a really really protective iphone 4 case , that will fix the antenna problem , and i hope you guys do it , dont wait until the iphone 4g or 5
This is a user to user help forum ONLY. You are not addressing Apple here.
The only thing a case does in this regard is prevent you from bridging the small gap in the antenna at the lower left of the iPhone with skin. The only thing. If you have a problem when using any case that prevents this and there are a number of 3rd party cases to choose from - the case industry for the iPhone (all models) is a significant industry by itself, call AppleCare or make an appointment at an Apple store if there is one nearby. -
IPhone 4 SIM Compatability/Antenna Problems
Basically, Im buying an iPhone 4 and wanting to use same contract on a Micro Sim, will everything work ok on iPhone 4?
Specificly, I currently have an iPhone 3GS on O2 with Unlimited Data, Unlimited Texts and 600 minutes. It is an iPhone Tarrif but i was wondering if i got O2 to send me a Micro SIM still on my same Tarrif (as i have about a year left on my contract) would everything still work on the iPhone 4 when i buy one? i tried to talk to O2 about it and they said it will work but i might not be able to use certain features (which was very unspecific and not very helpful). Anybody else tried to do the same thing?
nybody also experienced antenna problems on O2 in UK?Since you're running a seed version of iOS, you need to take this up in the forums to which you have access as an Apple developer program members. We can't help with issues involving iOS 5 in these public forums.

It sounds to me like your system is capable of connecting to the internet, but that it is unable to do much beyond this. It appears that these applications that you are trying to build in LabVIEW are exposing some of the networking limitations that exist on your machine. Unfortunately I do not know what to make of the port scan that you have provided. There can be many causes of networking issues that you would want to troubleshoot with your IT department or network card manufacturer. What I can do is to provide you with a list of ports used by National Instruments software. You will want to be sure that no packets are being blocked on these ports. Also keep in mind that when using TCP or UDP communication, you can specify the ports which you are using. Also, as a starting point, you may want to disable any antivirus software or firewalls that might hinder communication. I hope that this will at least get you started in figuring out some of these networking difficulties. Thanks,

Is Warrenty_upto really a date column? You say it is "stored as m/d/yyyy" but a date is not stored with a format in oracle - it's just a date and the format is applied when you retrieve the data.
In sql*plus if you Describe the table you can see the column type. If you select the data you only ever get a string.
I'm assuming :blk_main.to_date is a date.
