I know this would have been posted before, but I couldnt find it. Im getting a "download unsuccessful" message on my phone whenever download any type of file. Over 3g or 4g, from browser or market. Doesnt matter. Always unsuccessful. Works over wifi however. Ive cleared caches, cleared data, freed up heaps of room, unmounted and remounted the SD card, removed the battery, nothing works. Dont want to have to do a hard reset.
Also, tends to run sluggish at certain times.Eg, the day the download errors started occuring, the phone skipped badly when scrolling down facebook pages, and REALLY badly when drawing in snapchat.
