If you get error “Certificate Error, contact the application supplier”.
To accept all applications and solve this issue:

Go to Tools > App. mgr > Options > Settings.
Change “software installation” from “Signed Only” to “All” and “Online certic". Check to “off”.

This will most likely solve your problem. However,
please be aware that you turned off one extra layer of security for the device.
I wouldn't worry too much about malware or viruses but it is a good role of thumb to
only download and install applications from known sources.

tama si noosadz just try that one yan din ang gnagawa ko kung problem na ganyan ang phone ko sa mga games.

yep. i tried that one, ages ago...:weep: pero ayaw talaga nila mainstall..dami pa naman mga apps and games na gusto ko iinstall, unsigned o signed ayaw gumana karamihan mostly mga jar files... 0s 9.1 lng ang medyo sure shot na gagana..medyo disappointed nga ako e, kc dapat gagana cia, i mean dapat may backwards compatibility cia since high-end na ung 5700..

try reformat your cellphone:)

no no need to reformat compatbilty lng cguro problem ng phne na yan..check your certficate..
