Re: [Q] Uprade regular S3 to LTE S3?
For those who speak without knowing...
I have both i9300/9305.
Recently I bought a replacement lcd for the i9305 and was told that these are specific to the model and an lcd from the i9300 would not fit.
This is wrong. I have managed to use the i9300 motherboard on the i9305 LCD+midframe without issues. Also the fitment of all the peripherals such as antenna, front and rear facing cameras, buttons, film cables fit identically. All back plates, screws, heat absorber locations are the same.
I cannot be sure of the antenna module as its function so I ordered one for the i9305.
However, if the intention of the OP is to fit an LTE motherboard from a i9305 to a i9300 chassis, then its possible.
HOWEVER, an lte version from the US models wont work due to different configuration of the processor. For that you need the lcd made for that version of motherboard.
Hope it helps
