When accessing my Ubuntu phone, I a regularly asked to enter my device PIN. Now, while this PIN contains a "0", BUT I cannot activate any key of the bottom row, I cannot enter my phone any more.
I am a bit irritated whether this a hardware or a software bug. "Pressing" any key of the row above works perfectly. On the other hand, whiping things from bottom to top is almost non-working. So my assumption is that this is more a hardware bug.
Has anybody some idea: - Do you know this problem? - Do you know whether it's a hardware or a software bug? - Do you know what to do best?
I hope that I don't have to change the display once more, as getting the current one was quite a effort (the display being shipped from China).
