Low Display Brightness After Replacing Battery
I just replaced the battery in my iPhone 5S.
Accessing and replacing the battery was straightforward. Getting the touchscreen and display to work properly afterwords has been difficult. I lost track of how many times I connected / disconnected / reconnected the three small rectangular connectors in the upper right part of the phone. After multiple attempts I got the lines in the display to go away and the touchscreen to work properly.
I have two unresolved but related issues.
1. Un-even display backlighting brightness on the left side and near the top.
2. Brightness of the whole display is low compared to before dis-assembling the phone.
I suspect one of the three connectors is still not properly installed. I am reluctant to take the phone apart again.
Just looking to confirm my suspicions.
