    I walked in the rain and my phone went off before i got home. I left it for 14 hours to dry. Now the phone does not come up it just remained blank. I even charge it yet it does not come up. What do I do now?

    • Santosh Das says:

      Disassemble the Phone and Clean with IPA or Alcohol. Allow to Dry and Assemble and Switch ON. If this doesn’t works then Disassemble and Clean the PCB of the Phone with Flux and Give some Hot Air from some Distance and Assemble Back and Switch ON. If the problem is still not solved then there is Shorting in the PCB that needs to be checked by some technician.

      Did you try to update the software. Update the software using the Updater App which is preinstalled. I myself use Redmi Note 3 and can say it is one of the best phones available in the market. Try to Reset the Phone and then update the software.
