The switch stuck. (If-can-do-it-yourself) just open the phone then replace your keypad membrane switch. Or go to service center to replace the membrane

I for got the reset setting password samsung SGH-M 300


hi, you could try the default codes first.
1234 0000 or the last 4 digits of your phone number.
if that didn't work, you need to reset the phone.
*WARNING* this will erase all data & files on the phone memory.
Remove the sim card & memory card (if any) then turn On the phone.
*type in these codes, 82767*3855# *Phone will restart then place the sim card & memory card back in, power up the phone.
password should go back to default.
Hope that'll help you in some way.

Format N95


There are 3 methods to format the phone
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! IMPORTANT: back up your phone and memory card first! ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

First: if the phone menus work there is a; go to menu -> tools -> settings -> general -> factory restore. note: the defualt code is 12345
Seconed method requires you to enter these into the dial number area. Nokia Code : *#7370# : NOKIA Format phone (Soft Reset)
Nokia Code : *#7780# : NOKIA Factory Reset (Hard Reset)

Found these in the N95USERS fourm. Note: the defualt code is 12345


Third: is a button combination the needs to be done during the phone powering on
Hold down. 3, * and Green Call button While holding this combination press the power button once to start the phone Note: this does not require any codes; if this works the phone will prompt you to be set up again

None of these methods format the memory card
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! IMPORTANT: back up your phone and memory card first! ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

There are two methods to format the memory card
First: Go to menu -> tools -> utillites -> memory -> options -> format mass storage
Seconed: Connect your phone to your PC via the supplied USB cable. Then select Mass Storage mode on the phone. Once you PC has installed the Mass Storage device you can format the card from My Computer. Note: assuming Microsoft Windows XP or VISTA.
