good flow but no memory 1GB

I'm really pleased with the performance xcover2, very good fluidity. The opening of the functionality is fast. But the worst thing about this phone is its internal memory capacity. It was the biggest fault of Xcover 1 and this remains the biggest downside of xcover2. It is displayed with 4GB leaving a good margin by adding a microSD 32GB. The bad surprise is that in reality the user has less than 1GB which is very restrictive. For me it's a phone adventurer who will not support the implementation Helvetica flora field botany (1,7Go). I remain very frustrated. Only manipulations putting the phone out of warranty can remedy this problem.
