the first time my DP1's touchscreen failed is with 1.6 firmware, i updated it to 1.6.50 yesterday, nothing changed

when i charge it, the touchscreen always come back

is it a software or hardware issue ?

If you flash it back to before 1.6 firmware, and problem exists, then it is a hardware issue. Otherwise, it would be a software issue. I tend to think it is a hardware problem as I remembered someone also got irresponsible touchscreen. #107

And similar to before

cd /usr/local/bin
./tp_print_touch_data.sh > /root/test.log

then touch your screen several times. Finally, press ctrl +C to stop then

cat /root/test.log

What does it print?

unfortunately, the second morning after flashed to 1.6.50, touchscreen never come back. Failed to run tp_print_touch_data.sh in diagnosis mode

it’s a early version hardware bug

so i sent it to repair service

Yes, it's a hardware problem. My RP1 has been repaired now
