Mirror displaying handphone screen on monitor and vice versa with WiFi connection using LetsView

If you are using an iPhone or Android phone, and you want to duplicate and show your handphone's screen on your computer monitor, laptop screen, or even smart TV screen, together with audio forwarding, you can easily do that with a free software called LetsView.

The beauty of LetsView is that it can also do the other way round, to duplicate your computer screen onto your handphone. This is pretty useful to make use of your handphone or tablet as a presentation control device, which you can control your computer screen (which can be in turn projected out to a large projector screen) by touching your handphone screen. You can perform drawing and highlighting with LetsView too.

LetsView can also perform computer to computer screen mirroring.

All you need is:

• Download and install LetsView, free of charge, in both the screen mirroring source and destination devices. Supported systems including Windows, Android, Mac OS, iOS, and TV.
• Connect both the devices into the same local network. The network connection can be using WiFi or LAN cable. It can work across VPN tunnel too.
• Run LetsView in both devices.

Running LetsView app in smartphone is pretty straightforward. When the app is able to detect another device in the same local network running LetsView, you will eventually step into the following screen.

Phone Screen Mirroring means to cast your phone screen, together with phone audio, to a computer screen.

Computer Screen Mirroring means to cast your computer screen to the phone.

The screenshot below is captured from my computer monitor, showing the LetsView software displaying my phone screen on it.

When your phone screen is placed in landscape mode, the mirrored one on computer screen will also be displayed in landscape mode.

In your LetsView computer software, you also have the option for Phone Screen Mirroring and Computer Screen Mirroring. If you choose Computer Screen Mirroring, your computer screen, as well as your computer audio, will be mirrored to another computer running LetsView. The receiver will need to key in the PIN code as shown in LetsView of the source computer, for security purpose.

Before the computer screen starts to mirror to the receiver, a confirmation dialog will popup on the screen of the source computer, and you'll need to Allow it to complete the process.

The source computer can choose to either mirror the entire screen to the receiver, or just to mirror the screen of an application currently running on it.

Here is how the screen of the source computer will be shown in LetsView of the receiver computer.

LetsView is pretty useful when you want to work with your computer, while at the same time need to have a glance to your phone's screen from time to time. By showing the phone's screen on your monitor, it is very convenient to see what is on your phone's screen even without touching your phone.

This is also useful if you want to show both your computer screen and your phone screen to your audience in a presentation or live streaming session.

On the other hand, by mirroring your computer screen to your phone or tablet, you can transform your phone/tablet into a pretty powerful presenter device to remote control your computer screen. You can even write or draw on your phone's screen, and make it appears on the larger screen, by using LetsView whiteboard and drawing utility function.

Fixed Xiaomi Redme AirDots left earbud no sound problem

When you put on both the earpieces of the Xiaomi Redme AirDots wireless earbuds, by right you just need to Bluetooth connect to the right earpiece (Redmi AirDots_R) and the left earpiece will connect itself automatically to give you a stereo audio experience.

After some times of usage, I noticed that my left earpiece no longer automatically connects to the right earpiece to form the stereo audio, and it has no sound unless I connect to Redmi AirDots_L, which will in turn causing the right earpiece to have no sound.

Here is the fix to solve the problem:

Step 1: Unpair the Bluetooth device Redmi AirDots_R (and Redmi AirDots_L, if any) in your handphone's setting, or any other device that paired with the Redme AirDots earbuds.

Step 2: Shutdown and reset both the earbuds together.

Long press the button of both the earbuds together for at least 15 seconds. You will see the red and white lights of both the earbuds flicker alternately and then go out. Very important - do not release yet! Continue your long-press, after a while, you will see the red and white lights of both the earbuds flicker alternately again, and then go out.

You need to hold your long-press until the red and white lights would not turn on again.

In my first few attempts, I failed this Step 2 and the problem still remain unfixed, because I thought it was done after one time of lights flickering and go out. It turned out that there will be second or even third round of lights flickering and go out cycle, before the reset process is totally done.

Step 3: Put back both the earbuds into the charging box. Wait until both of them enter the charging state (red light on). Let the charging to continue for at least 5 seconds.

Step 4: Take out both the earbuds from the charging box. The left earbud should now be trying to pair itself to the right earbud, and the right earbud should now be trying to seek for a pairing device.

Step 5: Go to your handphone's Bluetooth setting, search and pair with Redmi AirDots_R. Your problem should be fixed by now.

Closing credit cards can be good for your credit score

You’ve already heard everything that there is to know about improving your credit scores. Conventional wisdom says to pay all of your bills on time; don’t have too many cards; have a good mix of credit types; and never, ever close any credit cards. That last isn’t always true though. Closing your credit cards can sometimes raise your credit score.

    

Yes, closing a credit card can adversely affect your credit score, but if done wisely, the impact might actually be a positive one.

When the credit agencies calculate your credit score, there are a number of different factors that are considered.  Some of the major ones are:

• Length of your credit history
• The number of open credit lines
• Debt to available credit limit
• Your payment history
• Average age of your credit cards

The bullet point that we will pay attention to here is the final one: the average age of your credit card. The credit agencies basically look at all of your open credit cards to calculate the average age.

Consider for a minute the following examples.

1. Our test subject, let’s call her Sandy, has a student credit card that she has had for 10 years. The card terms are horrible but it’s her oldest credit card so she’s afraid to close it. Chase Bank offered a sweet new credit card with a nice 0% introductory rate that she would like to take advantage of. She applies and gets a new credit card. If she has no other cards, what is the average age of her credit cards? --- The answer is 5 years.

2. Once the 0% rate offer expires, Sandy convinces Chase to offer her a rate of 1.99% for another year.  After the year is over, the interest rate jumps to 22.99%. Knowing that she can get better offers from a competing bank, she drops the new card in the trash like last week’s leftovers.  If she closes the card opened in just one year ago and keeps the one opened when she was a student 11 years ago, what is the average age of her credit cards if she has no other cards? --- The answer is 11.

By closing the new credit card, I, uh, I mean she, has increased the average age of her credit cards.

Here’s one rule to adhere to when closing credit cards: if you can, never close your oldest credit card. It doesn’t matter if it’s an old student card that you haven’t dusted off since Super Mario Brothers was the hottest video game in the stores.

On a side note, a trend that I’ve noticed is banks closing credit cards that cardholders are not using or drastically reducing the available credit limit.  They do this because they are not making money from you, and you are tying up available credit. They would rather transfer that credit card to someone else up to their eyeballs in debt who likes to hear the sweet sound of the cash register every time they swipe their credit cards. Hang on to that grandparent of a credit card with a death grip because it will help to increase the average age of your credit cards.  You don’t have to keep a balance on it, but make a purchase using that card once-in-a-while to keep the bank happy.

One last thing. Don’t forget that the number of credit cards that you apply for also impacts your credit score. This is called a “hard inquiry”. Those inquiries will stay on your credit report for two years, but the updated FICO scoring model, used by most lenders, counts them the most during the first year.  Also, if new credit applications are clustered together within a short-time period, the impact to your credit score will be minimized. If you will be dropping your newest card to get a better deal on another card please consider applying for a new card once the last inquiry has fallen off of your credit report.

As you see, you don’t always have to be held hostage by a credit card.  Getting rid of a credit card really can positively impact your score if done wisely.
