A very strange thing happened and wanted EE advice.  We have android phones and a iphone phones.   We are setting up some computers and its wifi router in an office.  In order to detect the best signal possible, we used an apps that would detect a wifis' router signal connection and see speed or fluctuation, etc. so we can discover the perfect spot for all devices.

For some reason the android phone had better reach to a wifi router and the iphone super less.  For example, the apps would display 121 mbps and the android phone and in the iphone would detect 23 or 50 mbps - placing both phones next to each other, inches away the wifi.  

Please advice on possible cause.

Thank you in advance.

Running Windows 7 Professional SP-1 32-bit, I need a way to have reliable notification when a new message arrives via Google Hangouts g-chat.  The notification needs to be visual, not auditory, because my desktop audio is muted during the time when notification is required.   If I am working on my desktop with another window in focus, the g-chat thread does not come to the foreground when there is a new message, which results in an unacceptable delay before I become aware of the message.  There is a Hangouts desktop App, but it doesn't work on 32-bit Windows.

An alternative to desktop notification would be an auditory notification on my iPhone.  I have tried installing the Hangouts App on my iPhone, but it does not deliver notifications, even though it is configured to do so.  My cellular service provider has done troubleshooting, and believes there is an issue with the Hangouts App, itself, because my iPhone delivers notifications for new text messages and new Emails, and the only notifications which are missing are from Hangouts.  If there is a third party application which would produce a desktop notification when there is a new g-chat message, or an auditory iPhone notification, that would be helpful.
How many people can access podcasts on iTunes and Google Play?

I have a podcast coming up hosted on podbean and distributed through iTunes and Google Play.

How many people could potentially access it?

I have a UIPageViewController which I am using for onboarding/walthrough screens but at the moment they only work with swipes. I added a button but I can't actually connect it and create an IBAction. I was able to programatically create a button that could print to console but I don't know how to get it to move the screens like swiping does.

class PageViewController: UIPageViewController, UIPageViewControllerDelegate, UIPageViewControllerDataSource {
    var pageControl = UIPageControl()
    // MARK: UIPageViewControllerDataSource
    lazy var orderedViewControllers: [UIViewController] = {
        return [self.newVc(viewController: "sbBlue"),
                self.newVc(viewController: "sbRed")]
    override func viewDidLoad() {
        self.dataSource = self
        self.delegate = self
        // This sets up the first view that will show up on our page control
        if let firstViewController = orderedViewControllers.first {
                               direction: .forward,
                               animated: true,
                               completion: nil)
        // Do any additional setup after loading the view.
    func configurePageControl() {
        // The total number of pages that are available is based on how many

I am working on an iOS application (in nativescript) that needs to get and post some data to an API in the background each 5 minutes. Now it seems that iOS is closing my application so I took a look at the long running tasks section of https://docs.nativescript.org/core-concepts/ios-runtime/how-to/BackgroundExecution but I fail to see how I should configure an interval now.

Also while it works correctly on the simulator (not thinking about the interval) with the debug fetch command, I can't get it to work correctly on a real device.
Hello and Good Evening Everyone,

        I am needing to know the voltage and amperage recharging requirements for an iPhone 5.  The reason I ask is that we have recently purchased a power strip which has 6 power outlets and 6 USB charging ports.  4 of the USB ports are 5v/1amp and 2 of the USB ports are 5v/2.4amp.  I want to make sure to match the voltage and amperage recharging requirements to what is offered on this power strip.

        Any feedback given in reply to this question will be greatly appreciated.

        Thank you

Microsoft Photos keeps popping up when I connect my iPhone to the PC.
How can I stop it from doing it?

Dear expert,

I have an email based on Hotmail company.

I always access it through the web browsers with no issue. Today, I have bought an iPad and iPhone and tried to configure them on both devices.
I went to the mail section and added them successfully but only one email had downloaded. I logged into the mail section again and change the download option to no limit but the rest of emails are not downloading yet.
iPhone 6s Plus screen and audio not working.  My wifes phone started displaying test patterns, then the display went dead.  For a period of time we could call it and hear it vibrate but no ring even though it was not on mute.

It also seemed to receive texts as they would be marked as Delivered.  I am contemplating replacing the screen, but since there is also an issue with the audio I am concerned that the problem may be elsewhere like the motherboard.

Is there common circuitry shared by both video and audio which would cause the screen and sound to go dead and if so is that replaceable?

I have a strange issue happening with a web site redirection. I have a HTTP Redirection Record added to my dns and it works for me and many other people. It is not working for everyone and every device. I have one that has an iphone and it works in Safari but does not work in Chrome. Uninstalled the app, reinstalled, cleared the cache etc. We are getting constant calls from people saying they cannot reach the site. Any ideas?
I am trying videos files that I took with my iphone to the PC and I got the error below:
I am trying to add a user profile on a iPhone 6 through Mobile Iron and keep getting this message during the install.  "Profile Installation Failed, The resource could not be loaded because the App Transport Security policy requires the use of a secure connection."  I have tried this on the users old iPhone 6 a new iPhone 8, on wifi, using just cell service and get same message no matter what I do.
me.com email account in Outlook.

After getting a new iPhone and changing the password of the Apple ID the icloud sync in Outlook not longer works and when it prompts for the password,
 imap.email.me.com or smtp the new password does not work. No setting in outlook changed in that time period. 993 and 587 and etc are all the same. It's a bit like a cert or other verification is needed.

PS: I've read most of the post on EE so far and found nothing that helps to date.
I would like an app for iPhone, which will allow the download  of PDF files to the iPhone.
There is study material on a specific website, where otherwise in Windows, the PDF study material is downloadable, however on iPhone, it opens the PDF file but within a window, and it does not allow for the download.
Any suggestions?   Safari and Chrome do not seem to work.  And when trying Safari and using the export option to iBooks, it basically sends a screenshot of both pages but not the full PDF document which might be about 60 pages.
I have one user with an odd issue.

When he sends an email with an attached photo from his iPhone to his company exchange email account it appears as embedded NOT attached.

This ONLY happens from his iPhone.

Other people can send attached pics from iPhones to his email and they arrive still as attachments.

What could be causing this???

we have configured a new Server 2016 DC and and new Exchange 2016 sever (on separate hardware).

We are not able to get our iPhone's to setup an Exchange account. The account on the phone will all 'green tick' but when trying to collect email is comes up 'account error' - 'unable to connect'.

This is a summary of what DOES work.
DC is working fine
Exchange is working fine
We have configured various DNS settings on our DC to reflect out external URL, Autodiscover, OWA and remote - they point to Exchange
We have a WIldcard SSL that gives us a secure SSL connection from outside our organisation to the DC's RWW and Exchange OWA
Internally Outlook clients can connect fine
Externally - NON DOMAIN joined PC's can configure a Exchange account and CAN send and receive email.
We have configured AUTODISCOVERY (URL 'A' and 'Cname' records) - and according to Microsoft's Remote Connectivity Analyser all tests pass - EXCEPT IMAP and POP which is due to the Wildcard SSL NOT being bound to those two protocols (but shouldn't be an issue- i don't think)

I have tried setting up the Exchange account on iPhone 6, 7, X iPad 2 and iPad Pro - none work and all show the same connectivity issue with Exchange.

We seem to have setup everything correctly - but clearly there is something missing.

Can anyone offer any support please
Thank you
