After having a lot of trouble with the default rom of my phone (reboots, frozen screens, wifi not connecting, etc), I decided to try my luck with other roms. After a few tries, I decided to try CyanogenMod 7, and I installed the psyke83 rom. But now I can't install certain apps. I tried from the play store, and tried direct from an .apk. Nothing: the phone reboots as soon as the app starts to install.
And I'm getting tired of this things. I don't want to go back to stock, with all the samsung apps consuming space and instability, but CM7 isn't making things easier for me, if I can't install apps (and essential apps like Maps).
Also, the thought of re-installing some apps, doing the setups allllll over again, fixing the agenda... any way to make a backup of all that things? I've read that Titanium Backup isn't worth it anymore.
So... What should I do? Stick to CM7 (3.0) and forget about installing apps? Go back to stock? Installing a new rom (recommendations will be appreciated)?
