One motor is slower than others

[TwoFourty]

Hey guys. Funny things. I took a small break from quads, because my frustration levels were really high because of burning vtx s and ripping rx anthennas. Today was a lovely day,so decided to take my weapon and burn a few packs. And guess what. Lol. It lifts off, quick check if everyhing is responding, angle mode, punch out, it is really slow, and dips a first motor arm. Sooo. A bit of examination and i realize that motor 1 is slower than the others. Any ideas why? Recalibrated esc s like a thousand time in every way possible i think. No changes. Disassembled the motor, cleaned it, no changes. Checked solder joints, everything is fine, no changes. Pls, enlighten me, masters.

Switch the motor with one of the others, see if the slowness follows the motor or stays with the esc

Okay. I swaped the motors around. But the problem is still staying on arm #1. Is it faulty ESC? Its littlebee 20a pro. Everything was fine before, and now its playing funny.

Yep ish, it could be faulty solder or wire, if not it is the esc.
