Hi everyone,

I have a Samsung Galaxy Tab S2 9.7 WiFi running Android 6. 1 (marshmallow). Until a few weeks or so, I wasn't experiencing any issues wall charging the device. Then, I suddenly wasn't able to wall charge the device. I tried using various combinations of wall chargers and charging cables to no avail. Out of sheer desperation, I bought and used a portable charger. Then, bam! No more charging issues.

My question is this: Why am I able to use a portable charger satisfactorily, but not a wall charger? It doesn't make sense to me.

Thanks in advance.

It looks like on board charging chip is damaged. Have you tried to connect USB cable from portable charger to wall charger? Maybe that will do.
