Problems after updating smartphone firmware.

[ChocoboLIVE]

Galaxy s2 update from firmware PDA:LA4 to PDA:LB1. I starting finally to realize my screen has yellow tint on them. Though unlike other users yellow tint problem, my screen covered with yellow tint everywhere. Is that supposed to be normal.

Also my screen only appear yellowing screen watching at 0 degree, watching at 10 degree or further decrease yellow tint color somehow. At 45 and up to 180 degree the yellow tint seems to be gone.
