iPhone one row is not working
In my iPhone 4 789 keys are not working if i press 7,8,9 key their top key 4,5,6 or bottom key *,0,# is displaying. the entire row is not working.if the scratched grad is present on the screen when these problem occur, if u remove the scratched grad the problem is solved,if there is no scratched grad when these problem occur i need to use the scratched grad to resolve these problem.After removing or using the scratched grad the screen will work fine for 1 week to 10 days then again the problem will appear back . example if i touch any option on that particular row up or below option is selecting. please provide the permanent solution. let me know whether it is lcd problem or any other.
Is this a good question?
