tyr a factory reset you will be suprised how little effort it takes and how much it would cost at a phone shop. Here are the instructions:

1.When the phone is off press and hold the power, volume and home button.

2. keep holding until the samsung turn on thingy with your phone name and model comes up, Keep holding, The title may come up twice but keep holding.

3.when the screen comes up, YOU WILL KNOW IT WHEN YOU SEE IT. Release the middle and power button but still hold the volume one down. This bit is tricky so you may have to turn it off and restart a couple of times.

4.Use the volume button to scroll through the choices and the home button to select the option.

5. Click on factory reset and then the only option that says yes.
BE WARNED THIS WILL CLEAR ALL DATA, PHONE NUMBERS (UNLESS SAVED TO SIM) APPS, MEMO'S AND ANYTHING YOU CAN THINK OF.

this will work though.

Here are a couple of codes to soft/hard reset/format a Nokia N95 mobile device:
Soft reset code *#7370#
Hard reset code *#7780#
If the hard format code mentioned aboive does not work, try the following manual method to hard reset/format Nokia N95:
+ Turn off the mobile device.
+ Press and Hold the following three buttons: the green Call Answer button, the "*" button, and the number "3? button.
+ While holding these buttons, turn on the phone and keep holding the keys untill the mobile phone restarts and prompts you to enter details.

I also have the exact same problem.
However, you don't need to take out the battery to re-power on the phone. Just hold the power button for a longer time (about 10 seconds). The screen will light up and the device will reboot.

Hi Friend,
The only solution u can do is as follows,

Initially switch off the mobile and then remove the battery and the sim card also
After 30 Sec u replace all the things in the mobile
Restart the mobile after 10 to 15 sec and then check it out,u wont get the problem again.

hard reset - contact your provider for instructions - make to back up all of your info to a card - then backup contacts via PC then ask them for codes to hard reset -

Try the following manual method to hard reset/format Nokia N95:

1) Turn off the mobile device.
2) Turn on the phone and quickly Press and Hold the following three buttons: the green Call Answer button, the “*” button, and the number “3′ button. keep holding the keys untill the mobile phone restarts and prompts you to enter details time and country.

Warning: Make sure the battery is at least 25% capacity so the phone will not power down during hard reset. ( Hard reset normally takes about 2 minutes only).

Warning: Hard reset will format everythings in your phone ( Your contact, calender, photos, installed Apps, Etc.) and the phone will be returned to its original state as if it was purchaced new.

( Mini memory card MMC) will not be effected :)
