The model is Samsung Trend Plus GT-S7580.
I found the info by this,
Settings > More > Storage > Used space
Device Memory:
Total-4.00GB
Min system memory 1.82GB
Used space 4.24GB;
Applications - 831MB;
Pictures, videos - 3.35GB.
I noticed the amount of storage space currently being used by pictures and videos taken using the camera is 3.35GB - Thats so pathetic:( How to fix this problem… I didnt found how to edit that storage space. Please… Help me…
