My new Samsung ace GT-5 is always on full phone storage.. I only download Facebook and messenger . My phone had a 4gb sd card memory.. it so slow when I'm connecting.. I don't know how to do ?

The Samsung Galaxy Ace phones are Samsung's low end/cost models. They don't have a lot of power, and aren't very fast. You shouldn't be surprised at the speed of the phone. You might want to consider a larger SD card, 16 and 32gb aren't that expensive right now. That could help. Also look up ways to speed up your phone. It could be the network around you or it could be your phone itself. If you're not getting good bandwidth then it will be slow.

My Samsung has same problem. I can keep using it by constantly forced stopping & clearing data from programs I'm not using (settings>applications) or moving some to sim card. The problem results from low memory to start andauutomatic updates to a number of programs fills up memory. Only solution is new phone.

I have a Galaxy S3 16GB, have had it for 2 years, still not even close to filling the internal memory halfway. Love that phone.

Thanks, NeedKarma. Going to buy new phone asap...
