Xperia sp 4.3 update issues

So I noticed a few flaws about this update 1 the illumination bar no longer goes with my music at high volume. 2 volume bar no longer appears after putting on new theme from Sony select 3 the ram is terrible now and last but not least the terrible white background drives me nuts

Now is much better but i don t know why ^ ^

17 H  - 98% change to 88%  so not that bad.

And operating system android  using battery change from about 70% to 4%

Well, it takes time for a phone to settle down after a major update.
