at first I'm in stock rom,then after a month using i get some errors with the touch screen,it become slow and slightly unresponsive,so I decided to try custom rom with sense 5 and hope the problem will fix,everything seems fine touch screen is good but after few days using it my softkey not working,and the middle of the screen become unresponsive,I try to reinstall the custom rom but still not working,so I went back to stock using guide from this thread http://forum.xda-developers.com/show....php?t=2402578
since I lost my backup files,after that problems still there,softkey still not working and the unresponsive problem still appear,I factory reset the phone many times but not help,but then I accidentally drop the phone from a half meter height table after that accident my softkey working back normally I can use it again like usually,only the unresponsive touch screen in the middle of the screen still appear..weird isn't it?
I test with multitouch tester and yes the middle screen touch has error,if I move my finger from the top to the bottom it will skip the middle screen like it's not touchable,another question,did one x+ detect only 2 fingers on multitouch?cause multitouch tester show that I have 2 touch only,just wondering
for the record my phone have a slightly screen flex at the left and right bottom corner only if I press that side too hard,I realize this and never press them too hard again,is that screen flexing that cause the screen become unresponsive?
