Hi, I'm so happy, that someone remembered about old xperias. They are great! However honami is xperia z1 (xperia xz1 is called poplar). Which halium version did you build? If there are so many problems maybe you could consider halium 9 porting with Generic System Image (GSI)? As there are Lineage 16 avaliable for honami (and other based on android 8 and later) so all after project treble where device specific code is moved to vendor partition. Read about the differences between previous halium version and 9 in GSI llink I'm not a developer but I hope it may be helpful Do you have any experience which you could find helpful and share about porrting UT to sony phones? I have couple devices which I'd like to be running UT, Xperia XZ1 compact (lilac) - now I'm working on it... Xperia XZ1 dual (poplar_dsds) Xperia Z2 (sirius) - same "z" family as honami Xperia Z3 compact (z3c) - same "z" family as honami
