hello there : )
I am on = android 5.1
phone serial number = sm-j500fgsmh (factory unlocked dual sim)
I am trying to find a good download location for a more up to date SM-J500F firmware/stock rom? (my location UK)
This may sound unlikely but i feel by updating it may fix at least one issue: 1. With "power button ends call" selected , the phone still will not respond or close when I have a call, I have to take out the battery( might be a sensor?)
2. The charging is slow but the battery lasts a fair good while once charged.
I have Odin3 ready and it can see my phone .
I wonder if anyone can recommend a United Kingdom version and location to download?
Thank you for any help you may offer. : )
