Hi guys I currently have the S3 and going to upgrade to the S5. However, I played with my friends new S5 and he hasn't got any real power hungry apps installed and i find it had to believe that when the phone is in idle mode it is using 1.4GB of RAM with "no tasks running". Is it just his phone or does everyone have the same issue? Also his phone makes a creaking noise when squeezed is this also a common issue? thanks in advance. I'm considering either buying this phone or m8 or wait for a month and see whether the s5 Prime rumors are true and get that.
