I have Samsung Star s5233 WIFI. It is working well overall. But it shows an error
"Unsupported resolution"
when I try to watch videos on youtube. almost 95% of videos from youtube site are not playing.
Although they used to play in the beginning....
What to do...

?
My WIFI connection is extremely fast, giving 100kb/sec speed so no speed problem and general internet surfing is also great.. Even youtube vidoes copied from PC are working fine within phone...it is just that youtube within mobile is not working in an ok manner as it used to, earlier..?
Do I need a Hard reset? If yes then how to do it...
Do i need to upgrade firmware...

or claim warranty...
or live with it..

Urgent reply required..as I love this phone....
