The Truth About Samsung Knox: Security or Warranty Trap?

You've hit on a point of frustration for many users of Knox secured devices. Is this built-in security platform a benefit to the average consumer, or just a digital padlock that prevents you from customizing your device and conveniently voids your warranty?

Let’s be clear: Knox is a lot more than a warranty trigger, but the consequences of breaking it are severe.

What is the Knox Fuse?

At its core, Knox is defense-grade security, starting with hardware built directly into the phone's chip. The "fuse" is actually an irreversible e-Fuse (electronic fuse) called the Knox Warranty Void bit.

• Its Function: It constantly verifies that your device is running only official, Samsung-approved software. The moment you attempt to gain "higher-level access" (like rooting) or install a custom OS, this fuse trips permanently from $0x0$ (intact) to $0x1$ (tripped).

The Inevitable Trade-Off

The immediate, cold fact is that a tripped Knox fuse will permanently disable critical, Knox-dependent consumer features:

• Secure Folder Lockout: As you point out, if a thief manages to trip Knox to bypass the lock, your Secure Folder data is locked forever. The data is secured even from you, the owner. The security system worked by making the data inaccessible to the compromised device.

• Samsung Pay/Wallet: These financial apps rely on the $0x0$ integrity status to guarantee a secure transaction environment. They will cease to function.

Conclusion: Is There Any Benefit for the End User?

While the warranty-voiding is frustrating, Knox provides real, tangible benefits that most consumers use every day:

1. Secure Folder: It enables the encrypted, isolated space where you store sensitive files—a feature impossible without Knox.

2. Payment Security: It ensures that your payment methods are protected by hardware-backed security, giving you peace of mind when using Samsung Pay.

Ultimately, Knox is the unyielding security foundation. For the vast majority of consumers who never root their phone, it's a silent guardian that enables core features. For the enthusiast, it is the uncompromising obstacle that forces a choice: Customization and root access, or defense-grade security and your Secure Folder.

It’s the cost of hardware-backed, government-certified security.

Conclusion
My understanding is that this knox security is  only made for manufacturer benefit.  as end consumer will not be able to take any benefit from it. 
As if a physical fuse is blown  secure data folder wont be accessable in life time. 
there are many chances some 1 try to aceess the root of the system to unlock after snatching or lost and found case. etc

Transpose duplicate data from columns to rows in excel.

I was working on a project where I encountered a challenge. There were over 14,000 rows of data, and many rows were repeated based on values in Column A. To address this, I wrote a macro to move duplicate entries into rows, aligning them horizontally. I’m sharing this macro with you—feel free to use it and leave feedback!

Managing data in Excel can become tricky when you have duplicate values in one column and want to organize related data into rows for easier analysis. This guide walks you through a simple VBA macro that transposes such data efficiently.

Example

Name	Subject
John	Math
John	Science
John	History
Alice	Math
Alice	English

Goal

Name	Subject 1	Subject 2	Subject 3
John	Math	Science	History
Alice	Math	English

When to Use This

This technique is useful when:

• You're dealing with survey data or logs with repeat entries.

• You want to summarize values per entity (e.g., customer, student, product).

• You want a flat structure for reporting or exporting data.

 

How to Use the VBA Macro

1. Open the Excel File

Make sure your data starts in Column A (Names) and Column B (Values) without any blank rows.

2. Open the VBA Editor

• Press ALT + F11 to open the Visual Basic for Applications editor.

• Go to Insert > Module.

VBA Macro: Rearrange Duplicate Columns into Rows

Sub rearrange()

Dim a, n As Long, i As Long, u()
Dim g, m As Integer, k As Integer
a = Range("A1").CurrentRegion
n = UBound(a, 1)
ReDim u(1 To n, 1 To 5)
For i = 1 To n
    If a(i, 1) <> g Then
        k = k + 1
        g = a(i, 1)
        m = 2
        u(k, 1) = a(i, 1)
        u(k, 2) = a(i, 2)
    Else
        m = m + 1
        If m > 5 Then ReDim Preserve u(1 To n, 1 To m)
        u(k, m) = a(i, 2)
    End If
Next i
u(1, 1) = "Macro output"
Range("E1").Resize(k, UBound(u, 2)) = u
End Sub 

Run the Macro

• Close the editor.

• Press ALT + F8, select TransposeData, and click Run.

Your transposed output will appear starting from Column E.

How It Works

• It creates a dictionary with names as keys.

• For each duplicate name, it stores values in an array.

• Then it writes each name and its values horizontally.

Tips and Customization

• You can change the input columns if your data isn't in A & B.

• Add sorting or filtering before running the macro for cleaner output.

• You can adapt this script for three or more columns as needed.

How to Save User Defined Function (SpellNumber) in Excel to work with it on all workbooks? (By One OF MY FRIEND --NB--)

Here's a refined version of your instructions for clarity and readability:

Step-by-Step Guide to Creating and Using a SpellNumber Add-In in Excel

Follow these steps to create a custom Add-In that converts numbers to words in Excel:

Step 1: Create the Add-In

1. Open a New Workbook: Open Excel and press Alt + F11 to open the VBA editor.
2. Insert the Code:
   • Paste the VBA code for converting numbers to text (words) into the module.
3. Save as Add-In:
   • Go to File > Save As.
   • Select the file type as Excel Add-In:
     • For older versions (Excel 97-2003), choose Add-In 97-2003.
     • For newer versions (Excel 2007 and later), choose the simple Add-In option.
   • Save the file with a memorable name (e.g., SpellNumber).
4. Close the VBA Editor: Press Alt + Q to close the VBA editor.

Step 2: Enable the Add-In in Excel

1. Open Excel Options:
   • Open a new Excel workbook.
   • Click Office Button (Excel Menu) > Options > Add-Ins.
2. Manage Add-Ins:
   • At the bottom of the Add-Ins window, under Manage [Excel Add-Ins], click Go.
3. Activate the Add-In:
   • In the pop-up box, you will see a list of available Add-Ins, including the newly created SpellNumber.
   • Check the box next to SpellNumber and click OK.

Step 3: Use the SpellNumber Function

1. Enter a Number:
   • Type a numeric value into any cell.
2. Insert the Function:
   • Go to the Formulas tab and click Insert Function.
   • In the Category dropdown, select User Defined Functions.
   • Find and select the SpellNumber function.
3. See the Result:
   • Once selected, the SpellNumber function will convert the numeric value into text.

Enjoy the solution!

About User-Defined Functions (UDFs) in Excel

Excel allows you to create custom formulas, known as User-Defined Functions (UDFs), using VBA. These can be used just like built-in functions such as SUM() or VLOOKUP(). UDFs expand Excel's functionality, especially for advanced calculations or text manipulations.

Example: Celsius to Fahrenheit UDF

Here's a simple example of a UDF to convert temperatures from Celsius to Fahrenheit:

Function CtoF(Centigrade As Double) As Double
    CtoF = Centigrade * 9 / 5 + 32
End Function

To use:

1. Enter a Celsius value in a cell.
2. Apply the CtoF function in another cell to get the Fahrenheit equivalent.

With these steps, you can create and use custom UDFs for various tasks in Excel. Let me know if you need help with any specific function or task!

Convert a numeric value into words in MSEXCEL

Steps:

Open EXCEL

press Alt+F11
Go to Insert>Module
paste the code below
Press Alt+Q
save it
go to excel sheet insert formula
SpellNumber()

put the value in (32) to convert to word

NOTE
its in Doller/cents
if you like to change the currency
simply search and replace
Dollars with []
cents with []

on request of a friend
if your currenty value is high

replace
Cents = GetTens(Left(Mid(MyNumber, DecimalPlace + 1) & _ "00", 2))
With
Cents = GetHundreds(Left(Mid(MyNumber, DecimalPlace + 1) & _"000", 3))
