Tuning your phone’s calculator

I use calculators a lot, but I don’t always have one with me. Yet my phone is always in my pocket. I should use it, but the calculator on Sony Ericsson phones is rubbish, we all know that. But this problem can be fixed!

The first thing we need is the replacement, a new calculator, which is a java application:
We also need the original file of the phone, you can get it following this tutorial, or using JDFlasher, also you can download it from the internet, or extract the FS (tpa/preset/system/menu). file is not the same on different phone types, so you must get it yourself.
You need XS++ (FSX), or Far Manager / JDFlasher to upload the new file we are going to make.
Optionally, you should obtain a good text editor, with syntax-highlighting (xml), try this: Notepad++.

1. Upload the calculator to the phone and install it, as you install any other java application (File transer mode or MyPhoneExplorer).

2. Open your file in the text editor of your choice. From now on, I’m going to use Notepad++.
Click the Language menu, and select XML.

Now search for calc (with Ctrl+F), and you will find the following text:

<element id=“Application_Calculator_Id”>
<label type=“name” textid=“MENU_CALCULATOR_TXT” />
<label type=“helptext” textid=“MENU_CALCULATOR_HLP” />
<icon pos=“left” source=“internal”>CALC_CALCULATOR_MENU_ICN</icon>
<link type=“internal” />

The line we are about to modify is: <link type=“internal” />, replace it with
<link type=“java” javasuitename=“JvoCalc” javasuitevendor=“Jvojava” javasuitepoint=“JvoCalc”/>

Now it looks like this:

<element id=“Application_Calculator_Id”>
<label type=“name” textid=“MENU_CALCULATOR_TXT” />
<label type=“helptext” textid=“MENU_CALCULATOR_HLP” />

<icon pos=“left” source=“internal”>CALC_CALCULATOR_MENU_ICN</icon>
<link type=“java” javasuitename=“JvoCalc” javasuitevendor=“Jvojava” javasuitepoint=“JvoCalc”/>

Save the file and upload it to tpa/preset/system/menu folder (as or read on.

Optional, yet useful!
You can also customize how the phone calls the menu item for Calculator, for example, call it “Professional Calculator”.

You have to modiy <label type=“name” textid=“MENU_CALCULATOR_TXT” />, to have
<label type=“name”><text>Professional Calculator</text></label>.

So it will look like:

<element id=“Application_Calculator_Id”>
<label type=“name”><text>Professional Calculator</text></label>
<label type=“helptext” textid=“MENU_CALCULATOR_HLP” />

<icon pos=“left” source=“internal”>CALC_CALCULATOR_MENU_ICN</icon>
<link type=“java” javasuitename=“JvoCalc” javasuitevendor=“Jvojava” javasuitepoint=“JvoCalc”/>

You can do the same trick on helptext if you want to, that is the text that you see when you press the right soft key in the menu.

Save this file and upload it to the given place.

Note: When you are renaming in <text> tags, you cannot use Central European Characters, if you want to use them, you must use HTML character codes, but only with numbers so the aacute will only work if given with its ASCII code, not the aacute word itself.

JvoCalc inserts an operator when you press * and a dot when you hit #. When you press the right soft key, you can insert e, pi, squre root, sin, cos and many others.

That’s it, now you have a far better calculator on your phone.

    cool …. can we use notepad or word???
    or firefox ??
    sorry 4 this stupid question.

  2. Peti says

    To edit No, notepad and word maybe, but I doubt Firefox can be used as a text editor.

  3. iceanddark says

    keep getting this error “error occur in the file. this may render the menu unusable”

  4. Akshay says

    then its either incorrect editing on your part
    or incorrect tutorial here !
    tutorial to me seems fine… check again please

  5. iceanddark says

    ok… fixed…it should be ” and not โ€œ

  6. iceanddark says

    sry error in previous post…it should be ” and not โ€œorโ€

  7. Peti says

    The tutorial is all right, it worked for me. ๐Ÿ˜›

  8. Akshay says

    Peti dude nicely advertises the programs that he uses … lol

  9. Peti says

    Yes sure. ๐Ÿ˜‰ If you are looking for a flawless file manager for Windows, check Total Commander Ultima Prime – . ๐Ÿ˜€

  10. Nazgulled says

    Is there a better looking Java calculator than the one recommended here?

    I mean, I don’t need a professional calculator on my phone (but that could be cool) but I don’t really like the look and how the default calculator works and I was looking for a better one.

    I tried JvoCalc and didn’t like it at all..

  11. Peti says

    This is the best I could find. :S
    But as soon as I find something better, I will modify the tutorial.

  12. amigo says

    hey guys!! can you suggest some cool applications for k800i like bt hack, world clock, converter etc and where can i get those? just want to ask also if there’s a way to store more messages to your “saved messages” folder? maybe you should also post a video tutorial for this coz its hard for noobs like me? thanx and sorry for my english!!!

  13. Akshay says

    hi amigo.
    no way to increase stored message beacuse it clogs the phone processor badly..
    applications you can download them from

    we don’t usually discuss about applications here.
    but may be we will if we need to do so.
    at our forum.. yes we talk about them also.

  14. amigo says

    many thanx akshay for your quick response!! btw i’m a little bit confuse in this tutorial coz it says ” we need the original”. what are you reffering to? is this the that can be replaced by menu modding or changing the icons of the phone? so for example i’ve already uploaded the iphone menu in my phone, do i have to upload again the original so that i can perform this tutorial for my calculator? sorry, i haven’t tried patching my k800i coz it’s CID53. please inform us if the newest version of X++ that supports CID53 is available already. More power to you!!

  15. Peti says

    That should be the one on the phone right now. So if you are using iPhone stuff, you should edit and upload that

  16. amigo says

    oh, so you mean everytime i replace/mod my phone’s menu, i should edit the that comes along with the menu pack? thanx a lot man!!

  17. Peti says

    Yes, of course, the pack needs its own menu, and this trick needs modification in the current menu.
