Thread: Primul smartphone cu 4GB RAM!

    Primul smartphone cu 4GB RAM!

    Ati auzit de ZTE? In caz ca nu stiati, ZTE este o firma de telecomunicatii din China, firma care, pe baza vanzarilor din anul 2012, este clasata pe locul patru la nivel mondial. La inceputul lui 2014, acestia au prezentat modelul Grand S II. Telefonul vine cu niste specificatii de top: display de 5.5" cu rezolutie full HD, 2GB RAM, vesnicul Snapdragon 800 ruland Android 4.3. Conform unor leak-uri recente, acestia se pare ca pregatesc o versiune "bumped up" a lui Grand S II care sa aiba 4GB RAM. In cazul acesta, am avea de a face cu primul smartphone cu o memorie RAM atat de mare.

    ZTE nu sunt straini versiunilor diferite pentru acelasi smartphone. Din gama lor de produse, Nubia X6 se vinde in doua variante: una cu 2GB RAM iar cea de a doua cu 3GB RAM. Avand resurse atat de multe, am putea sa vedem si o rezolutie peste fullHD, probabil 1440p.

    Pentru o arhitectura 32bit, cei 4GB RAM sunt maximul posibil. Samsung a vorbit despre module mobile de 4GB de curand. Probabil vom vedea cat de curand telefoane cu 4GB RAM, dar sa fie chinezii primii?

    Stai linistit... dupa ce vor trece la arhitectura pe 64bits... cred ca vom vedea Android cu 8GB RAM si 16GB RAM in maxim un an. Ceva trebuie sa justifice pretul, nu?

    Android e un sistem de operare foarte neoptimizat sa nu spun extrem de prost. Asa ca posibil sa aiba nevoie de 16GB cand o sa treaca pe 64 de biti. Si probabil va avea lag si atunci.

    Windows 8 si iOS sunt cateva zeci de clase peste Android in tot ceea ce inseamna un OS pentru mobile.

    Nu neg, insa trecerea de la Dalvik la ART e primul pas bun cu adevarat facut in ultimii ani (asta pe langa mici tweak-uri si optimizari). Pentru cei care nu stiu diferenta, un mic copy/paste:
    What is Dalvik?

    Dalvik is the process virtual machine (VM) in Google's Android operating system. It is the software that runs the apps on Android devices. Dalvik is thus an integral part of Android, which is typically used on mobile devices such as mobile phones and tablet computers as well as more recently on embedded devices such as smart TVs and media streamers. Programs are commonly written in Java and compiled to bytecode. They are then converted from Java Virtual Machine-compatible .class files to Dalvik-compatible .dex (Dalvik Executable) files before installation on a device. The compact Dalvik Executable format is designed to be suitable for systems that are constrained in terms of memory and processor speed. Dalvik is open-source software.

    What is ART?

    ART is a project Google has been working on for reportedly for 2 years. The goal of ART was to produce a faster runtime that wouldn't suffer from the problems Dalvik suffers. Android Kit Kat 4.4 is the first operating system with ART included in developers options although it is unclear just how recent this version is. ART stands for Android RunTime

    Whats the Difference?

    The main difference between ART and Dalvik is when they compile app code. Dalvik operates under a JIT (Just In Time) compilation method which means that when developers make their apps, they partially compile their code into bytecode which is interpreted by the java virtual machine. Dalvik converts bytecode to machinecode as the app runs to increase performance (bytecode execution is slower than machinecode execution). ART differs from Dalvik by performing this compilation of bytecode to machine code at installation of the app and saves this to the phones storage (not ram).

    So Why Use ART?

    Using ART instead of Dalvik allows the system to use much less resources during runtime. When apps are running, interpretation of bytecode is not ongoing, this can reduce CPU load and RAM usage. The resulting effect is faster app startup times (reportedly almost twice as fast) and better in app performance. It should be noted that performance boosts will only really improve for the java components of apps. Apps like games which rely on the NDK or other languages will receive more incremental experience boosts.
    Personal, de-abia astept primul joc pe Android care sa ceara minim 4GB RAM

    Kitkat a scazut cerintele minime, nu e nevoie de mai mult de 512MB pentru a-l rula. Ce spune nurv acolo, este in necunostinta de cauza. Problema principala pe Android este faptul ca sunt zeci de producatori, de acolo si fragmentarea si atunci incep sa apara unele probleme. Eu unul nu am mai umblat pe un Android cu soft mai vechi de 4.4 din noiembrie, iar de atunci lag sau stutter nu mai exista.

    Pot sa compar Note 3 care rula 4.3 cu cel de acum cu 4.4. Diferentele sunt enorme, TouchWizz nu se simte cum se simtea inainte. De Nexus 5 nici nu are rost sa vorbesc, e de departe cel mai rapid si fluid telefon pe care am umblat in ultimele luni. E mai snappy decat un 5S si cu mult peste Note 3.

    ART-ul e insa in stagiu beta si nu e inca gata. Ultima data cand l-am folosit nu functionau toate aplicatiile si a trebuit sa ma intorc la Dalvik.

    Nu cred ca chiar 100% in necunostinta de cauza. Tehnologic Android e multe clase sub iOS. E si normal. iOS are in spate tehnologie extrem de matura care s-a perfectionat de-a lungul a cel putin 20 de ani. Android ar trebui rescris de la zero. Este un sistem de operare care e proiectat prost de la bun inceput. Ce fac ei acuma este un fel de hai sa dregem busuiocul, sigur, cu niste rezultate bune.

    Dar pana se va misca un telefon cu hardware-ul modest al lui iPhone 4, adica un single core cu 512 RAM, pe KitKat, cum se misca iPhone 4 pe iOS 7.1, va mai trece. Mnu, nu vorbesc in necunostinta de cauza pentru ca am avut zeci de telefoane cu Android [intradevar pana la 4,3 maxim] si acum am iPhone 4 cu iOS 7.1 si nu prea am ce sa compar.

    Galaxy S3 quad core cu nu stiu cati rami se misca mult, mult mai prost decat iPhone 4 single core. Si asa mai departe.

    Pai noi vorbim acum de ce era acum 3 ani pe piata sau traim si noi in prezent? Eu comparam situatia de acum, nu cea de acum 3 ani.

    Si situatia din prezent e atat de buna incat lista cu noutati din urmatorul KitKat (4.4.3) arata de zici ca-i lista de bufix-uri si cam atat:
    • Frequent data connection dropout fix
    • mm-qcamera-daemon crash and optimization fixes
    • Camera focus in regular and HDR modes fixes
    • Power Manager display wakelock fix
    • Multiple Bluetooth fixes
    • Fix for a random reboot
    • App shortcuts sometimes got removed from launcher after update
    • USB debugging security fix
    • App shortcuts security fix
    • Wi-Fi auto-connect fix
    • Other camera fixes
    • MMS, Email/Exchange, Calendar, People/Dialer/Contacts, DSP, IPv6, VPN fixes
    • Stuck in activation screen fix
    • Missed call LED fix
    • Subtitle fixes
    • Data usage graph fix
    • Internet telephony fix
    • FCC compliance fix
    • Miscellaneous fixes
    Nu zic, nu ma deranjeaza ca repara (poate cu ocazia asta o sa poata folosi si Cris Nexus 7-ul), dar nici nu putem vorbi de ceva OK cand vezi atatea bug-uri... Iar cei care nu au bug-uri si probleme pe Android, inseamna ca nu folosesc suficient smartphone-ul

    ART e cu 10 clase peste Dalvik daca mai folosesti si custom.Si multe aplicatii merg, chiar si cele modate. Singurul joc nu mi-a mers este RiptideGP2
    BTW singura probleme care le-am avut de sus sunt:
    -Camera focus in regular and HDR modes (fixes) [most annoying one]
    -Wi-Fi auto-connect, cateodata nu scana retele(fix)
    -Bluetooth, pur si simplu nu pornea(fixes)
