Hi there, I am hoping to upgrade my Galaxy Ace in the next few weeks as I am wanting to use more and more demanding apps and games and the phone just cant keep up with them. I have narrowed it down the the Galaxy nexus or the S4 (posssibly the s3). I ruled out the Google Nexus 4 as I want expandable memory and I dont really trust LG phones. I have been using a borrowed Nexus for the past few days and am preferring it to my current phone however I worry that because it is now two years old I am going to need to upgrade again much sooner than if i get an S4. Looking at the hardware the obvious choice seems to be the S4 however it is twice the price and I hear that Samsung added alot of unnecessary extras to this phone. I really like the interface of the nexus, is it similar to the s4? Does anyone have any advice? Is it worth paying twice the price to get an s4 over the Nexus? Have there been any significant glitches/issues with the S4? Thanks in advance.
