I've had my Lumia 800 for about a year now and I love it. There is one issue though, the clock seems to run faster than it should. I've tried setting it to automatic and it doesn't change, when I change it to manual and set it to the correct time after a few days it will be a few minutes faster, the more time passes the faster it gets. I've tried a few things like syncing it with Zune, even just leaving Zune running for a few hours in the background while my phone's plugged in. I'm thinking I may have to phone up but I thought I may try asking here as there may be a simple solution I'm overlooking. Any ideas? It's not a major problem but it does get infuriating!
clock is operated by the software of the phone. Hardware is not the problem. so 2 options to fix this, it either reset the device update. Try performing a reset and then let's see if it will fix it. But if it don't then all we can do is to wait for the updates.
