Thanks for the answers so far.
G0ULI the 1GB is the ROM, the RAM is 16 GB which is used to run apps. My current mobile which is being serviced has a 6 GB RAM which is rapidly filling. The mobile I am thinking about is the Wiko Lenny4 Plus Black Dual Sim or alternatively the Xiaomi Redmi Note 5A 16GB Dual Sim or Meizu M6 Dual Sim Black.
Any comments between them?
