  • Vel Murugan

    If use two sims and using inbuilt memory 16gb (3s) or 32gb (3s prime) instead of memory card, is there chance to phone get hanging up ir work slow ? Think use almost 75% of inbuilt memory.

    • HI Vel,

      Yes, there might be a chance of slowness when using 75% space. Not only Redmi 3s, every phone gets slow if the space is nearly full.


      • Tadbhavs Kumar Singh

        does the internal memory gets halved in these phones? I am asking that in maximum phones though the ibternal memory is 32GB but only we can use 16GB the rest is acquired by the Android apps.Does this phone also have the same kind of thing? Because as i am a heavy user and also this phone second sim slot can support either a nano sim or a memory card at a time??

        • Hi Tadbhavs,

          On initial boot, the prime version has 24 GB as free memory for user out of 32 GB.


  • Pritam Jha

    Can we use both slot with JIO 4G sim , if yes then please suggest how?

    • Hi Pritam,

      If you have 2 JIO SIMs, then only one will work. Because anyone SIM work on 4G and the other remains in 2G at a time. Jio works only in 4G network, so you can’t use 2 JIO SIM’s at the same time.


  • Shivam Singh
