  7. Hi Sir, i have a doubt. If we flash lollipop custom rom, will the actual os change i.e, will it support 64 bit computing or just the UI ?

    ReplyDelete
    Replies
    1. Hi,
      Yes it will actual change the OS, lollipop not 64bit. 64bit it depend on your cpu or processor mtk so lollipop will run on 32bit processor. It pure lollipop not just the UI only

    2. Ok. Thanks. So if suppose the SoC was MTK6732, it would support 64 bit. Right?
