I’m sorry to have to tell you that even without video evidence, the magistrates will simply take the police word for it unless you have evidence to the contrary. You may not have been making a call on the phone to make telephone calls or texts but it appears that you had it in your hand and were “using it”.
You can try that angle if you want to go to court but I’m afraid it’s unlikely to succeed as a defence.
If you do go to court and you are still found guilty, you would not only face a higher fine also prosecution costs.
I’m sorry, I wish the answer was more favourable but that is the view that the magistrates will normally take. They do believe the police.
The other thing of course is that you have admitted that you were using the phone and I cannot therefore suggest that you plead not guilty because that would be perverting the course of justice.
Can I clarify any points arising from this?
