Unresponsive screen (ZTE Blade)

[Guest fufa]

Hi guys,

I recently de-oranged my San Francisco phone and its working great; but not without a glitch though. Everytime I switch my phone on, the screen goes unresponsive and I cannot even unlock my phone. The only way to switch the phone off is by removing the battery and switch it back on again. The screen starts responding after about 9-10 attempts. Once it worked on the 4th attempt though. I am too scared to switch it off now. Has anyone faced similar problem?

Any help will be greatly appreciated.

Thank you.
