majestic 493K 3G asse Y touch invertito a seguito di cambio vetro touch rotto.

[demos81]

Salve a tutti,
sono un nuovo arrivato in cerca di un aiuto ( o almeno solidarietà psicologica..)
Ebbene ecco il mio problema:
Mesi fa si è rotto il touch di un tablet majestic 493K 3G con Android KitKat, e così ho riacquistato il display e l'ho sostituito. Fin qui tutto bene e il sistema vede l'interfaccia MA...
purtroppo l'asse Y del touch risulta come invertito a specchio (tocco in alto a DX e lui vede un tocco in basso a DX).
Non so come risolvere e non posso giocare su un ribaltamento del touch, quindi...chiedo:

Essendo android un SO aperto, è possibile correggere via software (agendo sui file JAR o comunque sul framework o quel che è) inserendo solo una inversione dell'asse Y???
Se si da dove potrei iniziare a muovere i primi passi per questo intervento?


Ho già effettuato il logcat del touch screen rilevando gli eventi.
Riporto di seguito il caso di touch intermittente su schermata iniziale e touch prolungato su schermata principale...

Ho lo stesso identico problema, scrivo nella speranza che tu abbia risolto il problema e possa condividere qui il procedimento.
