Using MB855 Photon- Unrooted
OS 2.3.5

Issue
Upon installing Nextlauncher 3D lite I faced 2 issues:
1. for the first time it starts an error occurs if I press activate
2. for the first launch it freezes for a good amount of time, and needs to be closed forcefully

While trying to exit Nextlauncher 3D lite from preferences-> exit, it again relaunches itself, and it happens everytime. I checked and found that it did not set itself as default launcher.

Now removed Nextlauncher 3D lite

Installed Go Launcher to check if MB855 default launcher is changed or no. Still nothing set as default. And now while pressing the HOME (with Go launcher running) key on the phone nothing happens.

After removing Go Launcher and pressing HOME key - MB855 gives a option window to select the launcher

Appreciate help with the above issues.
