800MHz 4g LTE

[thirteeneast]

I'm in the UK this band is supposed to work on this phone I've tried forcing it nothing seems to work.
My sim is 4gg (giffgaff) APN is set and I'm in an excellent signal area for 4g.

???

Work in my other phone's.

you're right, band 20 is supposed to work but unfortunately I'm on 3UK so can't check for you(though I think 3 does use some 800mhz spectrum depending on area) - so 3G works for you only? Have you tried to force 4g using the mtk engineering app(android settings>phone info>set LTE only from drop down menu)
