iPad image retention
I have an iPad Air 2. Recently it is suffering from a severe image retention problem. I had shut it down for more than a week. When I switched it on, after sometime it started to show the same symptoms. I tried some image retention fix videos but their effects are temporary. It first shows weird colours for the apps greenish pink and then severe image retention takes over. The workaround for this is turning on the reduce white point. But this is a temporary remedy. Are there any permanent remedies? Can anyone explain.
