The display text for my Samsung Galaxy S5 when in the lock screen is predominately blocks, as opposed to being regular text. This also occurs when in the drop down notification view, but there are no issues when it comes to viewing the text as the main screen or running applications. I haven't altered anything about the device, though it is a refurbished unit and this has only started to happen a week and a half after I had gotten it from Asurion.
