As of yesterday my phone has developed a major problem. Every 5-15mins the screen will flash up an odd lattice of colours and the phone will reboot, bringing up the Nokia screen again second after, it'll then beep. The really annoying thing is that this is now causing the battery to run down in a day or less.
I've tried a few things to debug this, getting rid of some apps that were running agents, removing the MMC card, changing the length of time till the screensaver came on but it's still happening. Anyone got any clues as to either what the problem could be or how I could debug the phone further to find out?
do you have all your data backed up? you could try a hard reset (format) by holding down the green key, the * key and the 3 key all at the same time as you switch on. this will delete everything and hopefully the fault as well
