General Can't Update of Download Apps

view story

http://androidforums.com – I had my Huawei Activa for about four months now and on Monday it said there would be an important enhancement for it, as it was installing the update it said FOTA error so i took it to a Metro PCS and all they did was a factory reset and it didn't reset anything at all. So today I noticed that i needed to update some apps so I removed some apps so i could update them. Now every time I try to update them it says insufficient space when i have enough space on my SD card in internal storage. (General)
