Sony Ericsson txt pro CK15i User Manual & Specs Overview

We have to tell you that Sony Ericsson txt pro can’t be categorized as Smartphone gadget due to there is no Operating System running inside this phone, instead the java programming seems to be the core of this phone software. Actually we wanna write one of sophisticated Smartphone by Sony Ericsson (SE), the Sony Ericsson Xperia arc S. But, due to the User Guide (UG) / Extended User Guide (EUG), of this arc S does not available yet, therefore we decided to wrote the Sony Ericsson txt pro (as it User Guide already released / available). SE txt pro has a series code name as CK15i. By this, we can name it as Sony Ericsson CK15i.

The design of SE txt pro is using slide side form factor. Just like almost all “pro” version, the slide means that you can “pump out” the physical qwerty keyboard in “open mode” but in “close” mode, you can use the “touchscreen” display. It has four rows qwerty keyboard with some of dedicated keys and for the display, txt pro comes with 3 inches diagonal diameter size with scratch resistant surface furnished for TFT Capacitive touchscreen.

As you can see at the right side picture below, it was the only tutorial we can get (in picture / image tutorial) on how you can work / assemble the SE txt pro for the first time. The tutorial that usually provided in the EUG such as how you can open the back cover casing of the phone, remove and replace the battery to/off its compartment, learning to insert and install the SIM Card are poorly not available in the PDF Manual (as far as we knew).

Although, for the tutorial on how you can make a call, tutorial how you can use the Wi-Fi to connects to hotspot Wi-Fi area (page 27), learning to connecting txt pro’s bluetooth to stereo headset or pairing it to others (page 26), using the Camera, using PlayNow or TrackID technology, listening to music are included and ready to be read via the PDF Manual EUG.

If you got your phone freezing frequently or the touchscreen stop responding, you can try the fastest solution for this problem by performing Factory Data reset aka Master Reset (Hard Reset). On page 31 of EUG, you can read the step by step instruction how to do Master Reset. Home Screen > Find and tab Settings > General > Master Reset > Reset all > Tab Reset > Done.

    • Korpsaw says

      This phone always does this after battery has been pulled it seems. I cannot seem to figure out how to fix it. It just says “Opening contact Information” for ever or the dreaded “Please wait” when attempting to send a txt message.

    what can i do to fix it???

    any solution??

    please help me!!



    1) File Manager – just download “x-plore.jar”

    2) Games – make sure u download n save it in OTHER. 240×400 screen resolution game and of course in jar format.

    For msg tone, zooming, self-restart n contact “please wait” problem still searching for solution.

    Anyways.. This phone just fine to tested some hacking thing..

    • Cyntha says

      Hey :)..thanks for the name of the file manager.
      I’ve been looking for it like,heavens know how long..
      I’ve got some solution for u. first of all, the msg tone can’t be changed. T_T. i think. Zooming, can’t in camera mode, can in video. In image viewer, to zoom, u have to tap longer than usual at the image and something will appear (im sorry no time to explain, try it yourself kay). i dunno abt the self-restart. But the contact holdup can be minimize by Factory reset. As told above. C: Hve a nice day,.

  36. Danial kazi says

    I am feeling very bad why i purchase this mobile have no file manager so i didn’t like that mobile and we cannot change message tone this is my problem
