I am unable to get into my gallery as it stated that last needed to delete files. I have an SD card which is quite full admittedly. I have deleted over 150 photos, some videos, heaps of emails, some apps and app data. I have cleared caches and it shows l have memory there but l still cannot sync any emails or get into my photos so l just deleted another 50 photos plus all my recent files l had opened and some documents and it still says l don't have enough. Please help!
