I own the Xperia Play now almost 4 months, and was now time to leave my opinion about the device here. From the exterior ago I find it just perfect. It is really great in the hand, regardless of whether making calls, sending SMS or playing, both in portrait or landscape mode. It is also by no means too thick, I think, as to narrow phones often not as good in the hand. Positive also the battery is noticed, this keeps really long since I mostly use the device throughout the day, listen to music, write games or SMS and it till evening, when I sleep, persevere. The shop is doing well right quickly. With just under 2 hours, it is again fully there. The sound is really good, if everything is through the speakers or headphones, not too low and also when calling clear. Here I am genuinely convinced of the phone. So far so good, but now I want to get to the hardware properties. The 1 GHz processor is sufficient, mine MHz is currently on 800 clocked down and it still boils down liquid. A nice side effect is that the battery is thus protected even more. What, however, does not go at the 380 MB internal memory! After one month, which were full with me! Blame it on the, in my opinion totally unnecessary preloaded games, none of which I have played only once, this can not install, and thus occupy unnecessary space. Preinstalled apps, such as Timescape and Video Unlimited running all the time with and consume important RAM in the background, which also does not really belong with 360 MB of the largest. Since not let uninstall, it was with me for a short time so that I had throughout only 30 MB RAM free, and the home screen has ended permanently when I used an app, or in a game was to additional RAM release. This of course is particularly annoying because you can never get out quickly go out of the game, without the Home Launcher needs to build for hours again until ... So these two things bother me but big in the mobile phone, which is why everything came down to the fact that I a had to perform root. This makes it a possible system Internal Apps how to remove Video Unlimited, which I never used anyway. After I deleted everything I did not need, such as Timescape, the default music player, the comic games (who has been playing The Sims 3 on his cell phone) was the mobile phone exactly how it should be! Quick when opening apps, I can change out whenever I want, without the menu is closed, everything runs quickly and smoothly! It is now really become a top mobile. The memory is released mostly to 100-150 MB! As already described zvor, I could phone now even underclock without having lost its performance! So if you have many apps and this will work similarly, they will quickly reach their limits here. Without root because nothing works! So please Sony, next time a little more flash memory and RAM and the option to remove the preinstalled botch and we really have a top unit. The Spielpad good is as nothing when everything takes hours to load.
