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

Hallo,

Ik kreeg net een bericht op mijn sony xperia dat er een nieuwe software update beschikbaar was, dus dat deed ik.

Ik keek in mijn telefoon en alles ECHT alles is veranderd en vind het echt geen fijn systeem zo. Kan er niet mee omgaan! 

Alles is anders,vind het raar **bleep** mijn software eerst was vond ik stukken beter

Ik zou graag het oude weer terug willen of kan dat niet meer? ik ga niet zelf zitten k=tten want dan weeet ik het wel.

Kan iemand mij helpen **bleep** ik mijn oude software van 15 minuten geleden weer terug kan krijgen
