check if the screen has deep scratches at the edge of the glass (especially when the screen is original). When heated and stressed, the glass will break at this exact place. So avoid mechanical action in these areas, if any.

lift the screen with the suction cup in the upper left corner (mechanically this connection is the weakest). Remember that the screen is a set of glass and a slightly deeper matrix. Do not push anything under the surface of the glass, it may damage the screen. If, the reasonable limit is 5mm maximum.

under the edge of the matrix (not a glass - it's important) slide a guitar pick or other flat tool (like an invalid credit card).

repeat action for the entire left edge of the tablet. In my case, three matrix support points were enough.
