The one that got overheat issues is Z3+ (SD810)

Z3 used SD801. Notorious problems are waterproof issues & pinkish color appears on center during camera shoots, I used Z3 back in 2015 then kaput due to water damage on motherboard, Sony Centre quoted RM1,800 to replace the board, I bought another Z3 (2nd) from Mudah 6 month later. also got waterproof issues and kaput too....Z3 stereo speakers were great but not too loud compared with HTC with boomsound & good stabilisations for video recording without OIS
