If you own an iPhone have you noticed the touch screen not as touch sensitive as it used to be? If so, it's probably not your finger causing the problem.
Turns out millions of iPhones may be developing a serious issue that's now being called touch screen disease.
It's not hard to find someone having touch issues with their iPhone.
Here in the noon time lunch crowd, Elizabeth Jackson said her iPhone 6 plus is becoming frustrating to use.
"There's sometimes when it won't respond when i go to text or open an app. It takes a while to open up."
Brianna Booker's iPhone 6 was in even worse shape.
"I wasn't able to swipe. I had notifications coming in, but I wasn't able to answer any text messages or phone calls."
The issue started appearing about six months ago, mostly on the iPhone 6 and 6 plus.
So many owners are reporting this problem it now has a name: "iPhone touch disease."
Repair shops say many people think it's just a problem with their glass touch screen, so they will bring it to a repair kiosk and ask them to replace the screen.
Unfortunately, that doesn't fix the underlying problem.
"It's not a screen replacement issue. You can replace screens all day, but it really has nothing to do with it."
Joel Theisler is the manager of a ubreakifix.com shop, a popular cell phone repair franchise.
"This is the mother board."
Theisler says the issue appears to be that the touch panel is breaking away from the electronics underneath.
"The touch IC chip on the motherboard is essentially separating from the motherboard, which is causing the loss of touch.'
A telltale sign of the problem is a light gray bar appearing occasionally at the top of the screen.
Theisler's shop charges about $150 to re-solder the board.
Apple is not commenting on the problem, but iPhone experts believe it may have to do with the bendability of the iPhone 6 and 6 plus.
So if your phone starts losing its touch, visit a reputable phone repair shop that is aware of the issue: a simple glass swap will not fix the issue.
My advice: if your iPhone is still under warranty, visit your carrier or the apple store.
If not, go to a shop that understands this problem and what needs to be done to fix it., so you don't waste your money.
