I have add some Glue on an old cubot p9 and yes, it stops the glass cracking to expand and keep the glass in place, but be sure that you will not glue the interior LCD while trying to glue the Digitizer. This will not be good, especially if you plan to reuse this LCD. If you have a lot of broken glass parts and the LCD shows behind the glass, or other pieces shown its risky to do it with super glue, just use removable soft transparent glue for PVC that is non corrosive, in such case..… If you have all the glass parts attached without gaps, you can do it to protect the digitizer to not crack more and keep in place its pieces. Always use Clear Glue and test it on other surfaces before.
