I just now discovered this discussion after trying to fix the same touchscreen problem on my c3-01. I replaced the digitizer and the LCD. Nothing helped. Actually, I made the situation worse because the phone won't even turn on at all now. Great...
I am having issues with my phone too. I upgraded my phone last July,had no problems with it, but within the last fortnight things have gone wrong.
The touchscreen has stopped working at one side which means I can't swipe to unlock it,or click onto any of the icons.The only way I can get the phone to unlock is by removing the battery,but this doesn't solve the issue with the icons.
Any ideas?I was going to take it into the EE store where it was purchased but not sure if they will do anything.

the C3-01.5 is a nice phone, but shame on Nokia for this touchscreen issue. It failed the 2nd time here.
First time it failes it was repaired under warranty (by goodwill), as I was told I broke it (which was NOT the case).
The touch failed even if the phone never fell down, has never seen any water etc. It is not a water related damage, as Nokia assumes.
As the touch screen worked from time to time, I could not believe it is totally damaged - the reason must be another.
As I did not want to live a 2nd time for several weeks without my C3-01.5, I tried to fix it by myself, and succeeded.
In my case, the connection between the screen and the ribbon cable seemed to loose over the time.
I realized it when I gently pressed the phone on its upper left corner, right between the speaker and the left corner. Then, the touch screen worked perfectly.
Best way is to lay the phone on a table, press gently with the back of a screwdriver on the upper left area of the phone (left from the "NOKIA" label), and try to use the screen. If it works normally now, you have the same problem as I.
My solution: I thought how we could apply some light pressure to the area the ribbon cable is connected to the screen. Do you know the small, round, self-adhesive patches made of felt, that you apply to the leg of a chair to prevent the chair scratching your wooden floor?
I disassemled the phone, used such a patch (height around 1mm), cut a small piece (around 2mm x 5mm), and applied it on the area whare the ribbon calbe is soldered to the touch screen.
Then, I reassembled the phone, and voila! it works like a new one.
All you need is a t5 screwdriver, a self-adhesive patch and the youtube video that shows how to disassemble a C3-01. Time it takes is around 15 minutes, do it slowly and careful!
