Continuity mistake: When Walt throws the pizza on the roof, it lands 5 rows up from the edge. When the camera cuts to on the garage roof, it's only 3 rows up. Also the amount of topping changes between the angles. (00:34:30)
Continuity mistake: Mike's car is not visible when Walt breaks into his own backyard. Mike is still there, as you see him hiding behind the corner, and later getting into his car.
Continuity mistake: When Walter takes Junior home from school, at first there are no shadows or sun hitting the ground in front of the garage. In the next shot the sun appears.
Visible crew/equipment: In the scene after Walter took his son from the school and parks his car in front of their house (before the pizza scene), you can see the camera mounted on a crane while filming the scene reflected on the car's windscreen.
Continuity mistake: Walter is pulled over by a cop. Before the stop, the cop car is to Walter's right. Walt looks in his wing mirror (driver's side) and the cop car is to Walt's left.
Visible crew/equipment: The camera equipment is visible in the bumper of the jeep in the scene where Walt drops Jr. off (before the pizza scene).
Continuity mistake: When Juan walks into the bar, he sets his hat flat on the bar counter. But in later shots, the hat is sitting on the edge of the bar railing. Most noticeable when he and Tortuga leave the bar.
Audio problem: When Jesse rings Jane's phone when it's cut off, Jesse is still pressing buttons but there is no sound, despite there being sound when he pressed buttons before.
Suggested correction: He only presses 2 buttons. Anything else is just something like his thumb twitching, like he's anxious or nervous. You see him call Jane's phone multiple times by only pushing 2 buttons.

Continuity mistake: The cigarette package on the counter at the start changes position without anyone touching it. (00:01:30)

Continuity mistake: When Mike and Saul are listening to the tape recording, the recorder is on a join of 2 pages. We then get a close up of the recorder and it's in the centre of a page. (00:05:35)

Continuity mistake: When Mike gets out to throw Walt into his car the back passenger door is shut but when he throws him in it's open. (00:08:35)

Continuity mistake: When Walt is talking to Jesse at the school, his grip on the box changes between angles. (00:17:50)
Green Light - S3-E4
Continuity mistake: In the scene where Walt is talking to Jesse in Jesse's car, when Jesse pulls out the bag of meth it is in a slide to seal bag. The bag changes between this and a regular ziploc bag from shot to shot. (00:19:30)
Green Light - S3-E4
Other mistake: When Gus and Mike meet up in the parking lot, Mike hands Gus a copy of Walter's medical report. When the camera pans down to show the report in Gus' hand, the patient name listed is Jack Test and not Walter White. (00:30:04)

Visible crew/equipment: When Hank pulls up on the side of the road to answer his phone, the camera crew are reflected in the Jeep's grill. (00:31:00)
Green Light - S3-E4
Continuity mistake: When Hank is standing between the ATM and the pumps at the gas station, the shadow cast by the roof over the pumps shifts between shots. The shot from away, taken next to the pole with the Indian logo was taken earlier in the day, casting a long shadow. The other shots have a higher sun which has moved by several hours.

Visible crew/equipment: Skyler is making copies and the scene starts with a shot looking down into the copier (the Green Light). When the shot lightens a bit as the copier continues, you can see the camera lens. This makes sense because the camera is sitting directly on the copier looking down.

Continuity mistake: When Jesse shows Walter his product at the parking lot, Walter first holds the meth bag with his left hand, but in the next shot it's his right.
