I got this Jiake V12 phone using android 5.1 using ATT. It replaced my broken LG G2 phone. The menu system and setups are very different. The G2 phone had a shortcut to close apps. AppKiller was downloaded to turn off apps otherwise they kept running in the background on the v12. I also loaded Evernote to keep track of things. Errors saying the memory was full and I should clear out the cache. I deleted everything (even my hone preferences) I could find. The phone also had a micro sd slot and I installed a 32 Gb card. Still no good. I found an app that could move things to the sd card and delete the cache. I had to delete evernote and appkiller to make room for this utility app. I ran the app to move things to the sd card and delete the cache. It cleared up a small amount of memory and only loaded a few directories to the sd card. Those directories are empty. No apps were moved. Then I deleted the utility app and tried to reinstall evernote. It says I don't have enough space. There is nothing else to delete. No additional apps are on the phone and I am using calculator, gmaps, todo, phone, address book, default browser, clock, messaging. I draw down the top menu and it has the messages: internal storage running out – some system functions may not work, 1 voicemail call, sync – too many calendar deletes, can't update apps – your device doesn't have enough space. Tried a data backup then a factory reset. Now no appkiller, evernote, or “all in one toolbox”. No photos, music, deleted phone history and messages and no memory space. This POS is getting harder and harder to live with. Does this phone have a fix or should I buy parts for the G2. hoader
