i luckily kept my 6%-broken touchscreen (A) from 3y ago which i had at that time replaced with this current one (B) - which just broke a few hours ago...
now, inserting that old just partially broken screen (A) seems to work as before, the upper 6% of the screen are non-responsive as before but at least i can use large parts of the screen !!! i may be able to live with that for the time being - while i will be waiting for a new spare part (C). so, in sum, it's not the worst case scenario this way...
anyway, i will be waiting patiently to hear back from Fxtec support team !
