Well , software can affect the hardware to certain degree .
And not fair for those who do not unlock their phone .
If the service center need to entertain those who void their warranty ,
those who are not must queue behind of them when they fix those ass O 's phone .
Its not the matter of the tint related to unlocking or not , its the principle and term and condition .
Sony and XDA clearly stated unlock bootloader will VOID the warranty but those idiot don even know how to read .
Ignorant is not a sin , but when they still want their warranty after they thrown it .......
I can only say FACE TOO THICK .
yes.. software can affect hardware certain degree... but for the well known yellow-tint issue... I believe it's not related to software... If your board,cpu/GPU fried due to overclocking after unlocked bootloader... then don't claim the warranty since its confirm void already...
Basically if you know the model have few issue and know that warranty is void... don't unlocked the bootloader...
