my phone is an old one, lg otimus e612 , now a weird problem has occured, many apps are installing like amazon, cache cleaner, uc, but most apps like titanium unlocker, updated play store app, fleksy keyboard, super su, kingo root app,etc are not installing and giving error like insufficient storage space or free up some space...these apps are from from play store and other sources also... it has really been a headache as i am trying to solve it from past many hours and i have tried most of the solutions on net like clearing cache, removing odex file from data/app and system/app, degrading play store but still it didn't solved, please give me good solution to this problem except a factory reset. My phone has 1 gb of space left, it doesnt has the feature to move apps to sd card so i link them using link2sd, this problem is now happening with more than 50% apps that i am trying to install, it's a rooted phone with kingo root, i have also patched some apps using lucky patcher,my os is jellybean.
