Two police officers had claimed they saw Lennon using the keypad on a phone while driving on High Street, in Glasgow's Merchant City last summer.
But Lennon was found not guilty yesterday at Glasgow's Justice of the Peace Court after stipendiary magistrate Josephine MacLean ruled there was no case to answer.
One constable had claimed Lennon drove past them as they were walking up the street and the other alleged they were facing the road after emerging from a lane when his car drove by. They both admitted not checking the phone Lennon was allegedly using.
Lennon, 42, from Glasgow's west end - who already has nine points on his driving licence - denied the charge of using his phone while driving his 4x4 Audi Q7 on July 26 last year.
Solicitor Advocate Liam O'Donnell, defending, argued that evidence Lennon was driving the car listed in the charge had not been corroborated because only one officer was asked to confirm the registration of the vehicle.
He also argued the court could not be satisfied beyond reasonable doubt that Lennon was carrying out a communication function on his phone.
Ms MacLean said: "Mr Lennon, I uphold the submissions made on both legs that there is no case to answer, you are not guilty."
The court heard from PC Maxine Shields, 28, who said she and her colleague were walking side by side along High Street when she saw Lennon drive by them while using his mobile phone.
The court heard PC Shields spoke to Lennon when he stopped at traffic lights - where she saw a Blackberry phone in the centre console of the car - and asked him to pull over when it was safe.
Ms Shields said she informed him of the offence.
During cross-examination, Mr O'Donnell suggested to the officer that she would not have had a "clear view" of the alleged incident as she was looking over a lane of parked cars to the driver's side. She said: "No, I had a clear view."
The court also heard from PC Martyn McQuillan, 30, who was working with PC Shields. He told the court they were emerging from Tontine Lane on to High Street.
Mr Buchanan asked where his colleague was and he said: "She was just standing next to me."
PC McQuillan said: "As I walked out of the lane I saw the car driving slowly past us north on High Street and observed the driver to be holding a phone in his right hand."
PC McQuillan said: "It appeared from what I observed he could have been sending a text message."
He said: "My colleague did ask what he was using the phone for."
PC McQuillan said he did not check Lennon's phone but added: "The driver showed us the phone and it was powered on."
The court heard he saw Lennon press the phone more than once.
Speaking after the case yesterday Mr O'Donnell said on behalf of Lennon: "He is pleased the case is over and he accepts there was a misunderstanding."
