  • Jennifer Maxwell

    Please excuse the off thread, but my problem is another. First, I know ZERO about computers. My problem is that every single time I want to watch a video on YouTube, I have to go to Secure Clean and push it so that the RAM drops in percentage used. It is the ONLY way that I can use YouTube and it works every time, but I am tired of this ritual!! Thanks for your help, in advance!!

    Took my wife’s S6 edge charger didn’t do any of the above first other than disabled first charge enabled again didn’t work.
    Fixes by taking my wife’s and now works then back to mine didn’t work now all I did was take out cable from charger and with my mouth blowed both ends of the cable and charger and voila now working again been working now since 3 weeks until now.

    Note is one the most common Phine/Table charger problems “dust”
    My sons old tab4 I occasionally clean with contact cleaner NOTE LET DRY OVER NIGHT and it charges normalt and hold battery again for much longer an better charge why Samsungs products are so like this is always been a problem

    Woorked 4 years at Samsung support start here always before attempting all the above many times is hardware u can’t see or meassure I fixed customers products so many times by using this method guide them through the process.
    Contact cleaner is UR friend having a can of air even better no need wait for drying 🙂

    • Jorge_C

      Under no circumstances should you EVER clean any electronic device with contact cleaner, which is basically just saline solution. This will cause far more damage to your electronics in the long run than it will save in cleaning. I can’t even believe someone would suggest such a thing. It doesn’t even matter that you dry it all off, the damage is being done from the second that liquid contacts the copper pins inside your charger port.

      Always use isopropyl (aka isopropanol) at least 91% (99% preferred), you can buy this in the drug store. It doesn’t contain any salt like contact cleaner does (which will corrode electronics quickly) or much if any water (which can cause shorts and destroy delicate electrical components, especially when its saline solution) and the solvent action of the isopropyl alcohol will clean just about anything in there while evaporating off within seconds on its own.

      So once again, DONT EVER USE CONTACT LENS CLEANER TO CLEAN ELECTRONICS. The fact that this guy would suggest such a thing points to a severe lack of knowledge of how the contents of the contact lens cleaner will affect copper (tldr copper doesnt put up a fight). Sure says something about the training (or lack thereof) Samsung is giving its own employees. Of course if this guy actually worked at Samsung support I’ll eat my own hat.

    Hi i want to post and say thank you for the suggestions!!! I was having an issue with a verizon s6 edge where all of a sudden the fast charging woulsnt work. I started freaking out because i dont want to have to pay for a new phone.

    In the past when this would happen I would just unplug the micro usb cable and it would turn back on. This was the first time i experienced the issue with the new update to android nougat.

    After searching i want to say that wiping the cache partition fixed my issue and now I am back to gast charging which was one of the main reasons i liked tbis phone.

    Thanks for the great work guys.
    Best regards
