    Default GS4 + RFID Key FOB = Slow Phone?

    Hey Everyone,

    I have a Samsung Galaxy S4 phone that has been getting ridiculous slow. It's constantly freezing and switching between applications is painfully slow. My text message app seems to be the hardest hit. Some messages aren't coming through and typing responses is very laggy. I can type a sentence out before the first letter even appears, often times this leads to the key board disappearing and the Messenger app closing.

    I have tried everything short of resetting the entire phone. Ive deleted almost all the programs on my phone that I have installed recently, everything within 1.5 months of me noticing a problem.

    One item that Im concerned about is, I just moved into a new apartment and the key fob they provided was way too large. I took it apart and removed the RFID chip and placed it between the back cover and my phone case. Its on the outside of the phone (not contacting the battery). Its what I use to buzz into my building and operate the elevator. Im wondering if this chip, when energized, is shoring something out in my phone. Could this chip be wrecking my hardware?

    Some information you might find helpful:
    Device Memory 6.2 GB used / 3.5 GB free
    On SD Card 14 GB used / 45 GB free
    General RAM at the moment 1.1 GB used / 672 free

    Interesting idea.
    Perfect way to test it is to remove the chip. If the abnormal behavior stops, then yes...it is interfering with your cell.

    I tried removing the RFID chip, but the behavior continued. I'm wondering if I've done permanent damage already.
