Nokia N95 tips
1.  In the “Profiles” settings of Nokia, there is an option: “speak out the name to be called” and choose “open”. Then go back to the laptop and press “clock” for seconds. It will succeed in calling wanted person via speaking out the name of his.
This function is realized by the software built in the cell phone itself that can recognize the voice calling. It seems that the function will take up much space.
However, it is not suggested to use the function, since its success rate is very low and always there is the problem like this: call jack but jane appears. If your voice is nearly same as that of computer, it will be good. You can do like this. In addition, you can use these two functions at the same time, 3D ringing and speaking out the name to be called, otherwise, the cell phone system will be halted.
2.  If you didn’t uninstall the program according to the common method, the cell phone may prompt you that the installation failed when you install the same program once again. Maybe it is a detailed adjustment to the 3rd generation Nokia S60 for the security. Therefore, it is necessary to be careful for the installation and the uninstallation for the programs.  
The important tips for the software installation of N95! Many friends can not run the program after installing *.Jar. Below is the solution:
a. When installing *.Jar program, you must use English to name *.Jar program file and it will work well. Some *Jar runs slowly, but do not worry. It will just take several seconds to run. (Generally less than 10 seconds)
b. If you want to manage *.Jar original installation file well, I suggest that you can create a folder, and put the English files *.Jar into it, as it is convenient to the classification.
By the way, the precious version of handay clock software is not compatible with N95 and when you open the clock function to work for you, then the multi-media button will become invalid.  Note: higher than 4.02 version can be installed to work well for this function. As long as the normal JAR program for N95 can run, it just has the differences between full screen and the half screen.
3.   N95 can look through the zoom of DOC documents. XLS files can be modified by the ranks of size, translation, the freezing window operation. PPT files can be displayed as the method of the full screen. As the version of FLASH players is a bit lower and larger flash will not be played. So will PPT, word, and excel.
4.   If you want to install the theme of Nokia N95 into the cell phone as much as possible. If you install the theme into the card, it will recover automatically to the default theme when you restart the cell phone.
Two methods of the theme installation:
a. Copy the theme installation software (SIS or SISX format) into the cell phone card and use “Y--browse” to complete the installation.
b. Use card reader or “data connection” of the data cable to copy the decompressed theme folder into the cell phone card. The path is X:\private\10207114\import\ (suppose X is the memory card).
The comparison between these two installation methods:
a. The process of the installation is very simple but it will auto create a file under the path: C:\sys\install\sisregistry. For example, C:\sys\install\sisregistry\a00000eb\00000002_0000.ctl. This will take up too much space of “hard drive C”
b. The process of the installation is relatively complicate, however, there are not any installation steps and it won’t create any file on “hard drive C” either. Of course it can not be installed on “hard drive C”
Choose the style of theme installation correctly:
Usually, some people will install it at the first sight of the beautiful theme without considering it is fitable for you or not.
a. Do not install the different model theme, or it may be out of shape.
b. Install the unpractical theme because of the beautiful stand-by image and the letterform of its function list, information, selecting bars, the outside screen etc is not very clear at all.
c. The installed theme is too large and some themes will be up to 1MB. It will affect the speed poorly.
The deletion of the theme:
a. If you use method 1 to install the theme, you can delete it in “program manager”. If there are too many themes, it may not be resolved. You can use “Y--browse” to delete the file on C:\preinstallAppscache.dat and try to delete on “program manager”. If still not, you can use the following method to deal with it.
b. If you use method 2 to install the theme, please remember the name of the theme and use card reader or “data connection” of data cable here: X:\private\10207114\import to find the theme folder, and then delete the folder.
5.   If you can not find or add the songs in the tab of “music” of N95, you may delete the original ones to update again.

6.   As for looking through the different content, Nokia N95 provides two different network browser accesses.
The browser under the main function menu is used for the common WAP web page and the support of EDGE ensures the web fast speed. For the browser under the application program, it is mainly used for the HTML content, supporting three letter styles, full screen mode, and the analogue mouse for assisting the pages up and down, left and right.
7.   The method that Nokia N95 makes wanted picture as the full screen wallpaper: To set full screen wallpaper, you must put the picture into your used Theme, and use S60 Theme Studio for Symbian OS to make your theme then add wanted picture into it. At last, combine them into sis files and install the theme into your cell phone. Here is ready for you to apply the theme onto your cell phone under the “settings” list.
8.   The method to run N95 and speed up
a. Only using a SIM card, N95 will run slowly. You need to clear the spam files on “hard drive C”. The simplest way is to replace SIM card with MINISD card for restarting the cell phone. For about 3-5 minutes, shut down the cell phone to change back SIM card. Like this, Series60 system will renew the data on “hard drive C”, auto clearing original useless files. If you are interested, you can have a try.
b. Shut down unnecessary background program. The camera won’t run on the background if it is not open. But as long as you have opened, even though it is shut down, it will run on the background in order to operate it faster. It is the same with card folder. In the running program interface, press “select” and then press “shut down the application program”. It will really close the using program.
9.   The batch deletion and the batch copy
The method to batch deletion and batch copy: Sometimes, we need to delete a lot of information or the images. It is boring to delete them one by one. At this time, you can do like this: option?check ?check all, after each file, a tick symbol will appear. And here, if you choose to delete, they will be deleted at a time. Another method is to check them one by one annually. Do like this: Press “pen type key” and then press direction key up and down to check them. Loosing them and taking the same action will cancel checking. Of course, even though they are checked, you can also make batch copy and batch sending.
10.   About video playback, it is very powerful. It can play RMVB files: 320*240, Real 8 or 9 encoding; AVI must be played by 3rd party players. RM files need converting to 240*320 with the conversion software, so do AVI files. If you use smart movie to play AVI files and had better use PC port itself. I use  Pavtube Video Converter to convert them and  it works well. You can have a try.
About parameters reference:
Avi (Divx) video: codec mpeg4, resolution 320*240, bit rate 240 kbps, frame rate 25fps/s
3GP video: codec Xvid, resolution 320*240, bit rate 256 kbps, frame rate 15 fps/s.
