How to remove spam calendar invitations from iPhone

Does your iPhone calendar have spam invites?

Hey iPhone users!  Have you recently had random calendar invitations mysteriously show up on your phone that you can’t get rid of?  Yeah, me too, and it is very annoying.  No matter what you try, you can’t seem remove them from your calendar.

Symptoms of a spammed calendar

These are the behaviors of the spam invites that I have recently encountered:

  • Several consecutive days on the calendar have repeating or reoccurring invitations with same name.
  • There is no Unsubscribe button for any of the spam invites.
  • Declining the spam invite appears to do nothing.
  • Long pressing on the spam invite in List View does not present a Delete button.
  • The web version of the calendar (, Gmail calendar, etc.) does not display the spam invites.
  • The original spam calendar invitation is difficult to find or may not exist at all in your email.

Where’s the fix?

If you’re like me, you have searched the internet multiple times for a solution.  Unfortunately, most of them don’t work anymore.  The reason why most of the solutions I found online don’t seem to work anymore is because spammers keep changing their methods and tactics.  They have to, to stay in “business”.

Well, I’ve figured out what you have to do to banish these pesky spam events off your phone.  This method works, at least for now.  There is no way to tell when this method will stop working.  Spammers are always coming up with more sophisticated ways to trick people.

Keep in mind, these instructions are for only for iPhone users using the built in Calendar app.  If you use a 3rd party calendar app, your mileage may vary.  Also, I am not an Android user.  Android phones may already have a way to easily remove spam invites.  For now, iPhone, does not.  In my particular situation, I am using an iPhone 15 running iOS 17.3.1.  I have a Gmail account and a Microsoft email address setup on my phone.  I am using the built-in Mail and Calendar apps that Apple provides.  The spam invitation ended up coming from my Microsoft account.

6 easy steps to remove spam calendar invitations

Follow these 6 easy steps to remove spam invitations from your iPhone Calendar app:

  1. Open the Calendar app and set it to List View.  Navigate to any of the spam calendar invites, but try to find the first one in the series if possible.

  2. Open the spam invitation that you want to remove.  Press the Decline button at the bottom of the screen.

  3. A pop-up window should appear.  Press Ok.  It will appear as if nothing has changed.

  4. You should now be back in the List View.  Now long press the spam invitation.  A command menu will be presented.  Press the Cut button in the top left corner of the menu.  Again, it will appear as if nothing has changed.

  5. Long press the spam invitation again.  A slightly different command menu will be presented.  This one will have a Delete button at the bottom of the menu.  Press the Delete button.

  6. A pop-up window will display, asking to confirm that you indeed want to delete the event.  Press the only option we care about, Delete and Notify.

And voila!  All the associated spam calendar invitations magically disappear from your calendar!  However, I wish we had the option to Delete without Notifying.  I’d rather not let the spammer to know I have figured out how to remove the spam, let alone supply the spammer with my email address.  If you are concerned about the spammer receiving your delete notification, you can temporarily turn off Wi-Fi and cellular data while you clean out your calendar.

Spammers are getting increasingly more sophisticated with their malware attacks.  Keep in mind that calendar cleaning methods that worked before, may not work later.  Hopefully Apple will update the built-in Calendar app to let us more easily remove spam calendar invitations.  Until then, stay safe out there, and don’t open any emails or invites you don’t expect or recognize.

Determining Optimal Viewing Distance

Determining Optimal Viewing Distance

Have you ever bought a new TV, only to find out that it was too small or too big for your viewing space?  Or maybe you have a room in your home and you want to know what size TV you should get for the space.  If you want an easy way to calculate the optimal viewing distance from your TV, look no further than this handy tool by Omni Calculator.

Optimal TV Viewing Distance Calculator

For the home theater enthusiast, figuring out screen placement and optimal viewing distance is crucial to maximizing the enjoyment of your investment.  You spent good money on a good device and want to enjoy the best picture quality possible.  This tool may help you estimate how far you should place seating from the screen.

All you have to do is type in your screen size and select the screen resolution from the drop down list.  Your optimal and minimal viewing distances are instantly calculated and displayed.  It’s just as easy as that!

But what if you don’t know what your screen size or resolution is?  You can gather that information from a variety of places.  Your TV might have a sticker on it, or if you still have the original box or instruction manual, it might be listed there.  And of course, you could look up the TV model online.  Sometimes, the model number itself will give you a clue to its screen size and/or resolution.  If you are interested in learning the secrets to decoding TV model numbers, check out this article posted by PC Magazine.

How to measure TV screen size

The size of a screen is the length of its diagonal measurement.  If you were to draw and measure an imaginary line from a bottom corner to the opposite upper corner, you would discover the screen’s size.  Screen size is always expressed in inches. For example, a 32″ screen has a diagonal length of 32″. If it has a regular aspect ratio of 16:9, then the sides of this screen are 27.9″ and 15.7″, respectively.  You can check our math with Omni Calculator’s Pythagorean theorem calculator.

Naturally, the longer the diagonal measurement, the larger the screen. But does bigger mean better when talking about TVs?  Not necessarily!  To determine which TVs are the best, we also have to take into account screen resolution.


So what does TV resolution actually refer to?

By now, you may have seen or heard of marketing terms such as “HD” or “4K” used to describe the features of TV model.  These terms are often used in describing screen resolution – or rather, the number of pixels on the screen.  A pixel is the smallest “dot” on the screen can accurately display color information. If you look really closely at your TV, you will discover that the lines are a bit jagged because they actually consist of tiny squares.  What you are seeing are individual pixels of the screen.

Screen resolution is a measurement of the number of horizontal pixels times the number of vertical pixels along the edge of the screen.  A screen is really just a grid of tiny pixels, similar to the multiplication tables they used to teach students in elementary school.  Screen resolutions are typically denoted by the number of horizontal pixels across the edge of the screen.  Typical screen sizes are defined in the table below.


  • 480p – 720 pixels by 480 pixels
  • 720p – 1280 pixels by 720 pixels
  • 1080p or HD– 1920 pixels by 1080 pixels
  • Ultra HD – 3840 pixels by 2160 pixels
  • 4K – 4096 pixels by 2160 pixels
  • 8K – 7680 pixels by 4320 pixels

It is important to note that screen resolution has nothing to do with screen size.  There are 70-inch televisions with 4K resolution monitors as well as smartphones outfitted with 4K resolution screens.  So those high-end smartphones have screens with very tiny pixels, while the pixels on a 70-inch screen are much bigger.  The Jumbotron screen installed at the Dallas Cowboys‘ AT&T Stadium, measures 160 feet wide by 72 feet tall (49 m x 22 m), made to display HD resolution video viewable from the stands, has pixels that are roughly 1 inch wide!


Calculating the ideal TV distance

If you want to calculate the optimal distance between you and the TV, you should know that a typical viewing angle θ lies in the range between 30° and 40°, as depicted in the image below.

Armed with this knowledge, you can start setting up a room and the furniture within it to take advantage of optimal viewing distance.  Although optimal viewing distances can be quickly estimated, there is a science to it all, which involves some pretty involved trigonometry.  If you really want to learn the math and science behind proper viewing distance, read the full article by Omni Calculator.  Or you can just use the calculator at the beginning of this article and save yourself a bunch of time.

Or just ask the professionals!

How to Avoid Wrong Number Scams

How to Avoid Wrong Number Scams


Have you received random text messages from numbers that you don’t know?  Sometimes, they just say “Hi”, or they appear to be for someone else and mistakenly sent to you.  Either way, they look like the come from real phone numbers.  Is it safe to respond to these messages, or are these a scam?

Most likely these text messages are a scam, not just a chatty Kathy trying to make friends.  Sometimes these messages just start out with a mysterious “Hi”.  The scammer is hoping the person on the other end will be intrigued enough to respond.  If they get a response, they now know they have reached a working number, and will likely call or text you more in the future.

Identifying potential scams

Some scammers use messages that seem like they are intended for someone else.  They might say something like, “Hi, Mike. I had a great time at dinner last night”, or “Hi Susan, I really enjoyed our lunch meeting yesterday”.

Many people respond out of kindness, letting the person know that they have the wrong number.  What they don’t realize is that is exactly what the scammer wants.  At first, they may sound friendly or apologetic, maybe even try to start up a conversation.  But eventually the scammer will send a link to a malicious website or ask for money as part of a bigger con.

If you are unsure whether a wrong number message is a scam, proceed with caution.  The scammer may send messages for days or weeks before doing anything suspicious, or they may use seemingly harmless techniques, such as sending a link to a cool product to check out.  However, this could be a link to a malicious website or to their landing page.  If this is the case, any personal information or credit card numbers entered on the website will be available to the scammer.

How to avoid wrong number scams

Here are some best practices to avoid falling for text message scams like this one.

  • Avoid responding to unsolicited text messages from unknown numbers, even if they seem harmless.
  • Don’t click on links sent in text messages, even if the person seems friendly or has been messaging you for weeks.
  • Type in any links to a site directly into your browser instead of clicking provided links in text messages or emails.  Links can be made to appear to go to one site, while routing you to another site.  They may even go so far as to create a fake site that looks like the real site.
  • Always double-check site URLs before attempting to log in or enter in personal information.
  • Check what options your mobile phone has for blocking and reporting suspicious senders.  Here are some instructions for iPhone (iOS) and Android.

It is important not to let your guard down, as these are tactics commonly used by scammers.  Remember, these scammers can be tricky.  If you find yourself unsure about the legitimacy of a text message, it is best not to respond.​
