I wrote a review on google play store mentioning a issue with the battery current value on my Gs7 (alaways 0).
You ask me to try to reboot the device and send an email if it still doesn't work.
So I've tried it and it still doesn't work. I even noticed that if i put a text with battery current value (which is always at 0), the widget show "loading" undefinitely and doesn't load until I load KWGT apps.
Several other apps works fine and display a good value.
I tried to play with the Autorisations and allowed all possible access to KWGT, still not working.
My GS7 is brand new from Orange France. I think Orange FR has slightly tuned the rom and/or the kernel and/or the radio rom...don't know if it can have and impact.
I also tried with KLWP and the same things happen. It surely has to do with the way you read the current.
I noticed that some apps let the ability to adjust the source of current value in a list with roughly 8-9 choice. The good value is always in there. May be a good workaround to have this ability.
My Gs7 is on Android 6.0.1, here is all the versions :
Model : SM-G930F
Kernel : 3.18.14-8888212
Version number : MMB29K.G930FXXU1BPH6
Hope you will find a fix cause it's the only thing that I need to complete my theme and your apps is so good, light cpu, huge customization, i don't want to use an other apps just to have the current...
