Last night I attempted to upload pictures from my phone to pc through a wifi network, all was fine at first and then the phone seemed to turn off, it would go blank and then come back. I tried again but it kept happening so I gave up. But now the phone keeps going blank for a few mins and then coming back. I reset the phone setting but the problem is still there. Regards Thomas

Sounds like possible DNS problem. Right click on the networking icon in the bottom right corner of the taskbar (the monitor shaped button or the bars if you use WiFi) and hit troubleshoot problems. This may detect invalid DNS settings and attempt to correct them
I have the same problem and i thought that resetting the phone may some how resolve it, but didnt, however it got sorted out when i turrned off the phone, removed the battery, put iit back on and restart the phone. Looks like the MAC address gets reset which caused the orignal problem and doing the above causes it it reset properly
same problem, broke my screen, ordered a new screen off ebay and replaced it. now it works fine most of the time but sometimes external display freezes. sometimes goes black, sometimes goes multicolor pixelated (full screen, in blocks, or lines) when this happens sometimes touchpad still works, others not. removing battery usualy temporarily fixes.
