Remember the Galaxy Note 7? Well, I am not sure there is a way to forget that device. It could have ended up being one of the best Galaxy Note devices, except it failed to reach the success Samsung had planned for it due to the battery issues. After that, Samsung tightened the battery QA process by a mile, and we never really had another incident like that. Now, Samsung is going back to the same supplier for the Galaxy S22 series.

According to a tip from The Elec, ATL and Samsung SDI will be supplying for the upcoming Galaxy S22 lineup. For those who do not know, China's Amperex Technology Limited was among the suppliers for the Galaxy Note 7 as well. Following the incident, ATL was cut from Samsung's battery supply chain.
