According to sammobile, a considerable number of Galaxy S20 ultra and Galaxy note 20 ultra users have been complaining about problems with wireless charging after the recent firmware update. More and more aircraft owners have exposed this problem in official and unofficial forums. It is reported that this problem seems to occur only on some third-party chargers.

According to the user's report, the problem includes continuous interruption of wireless charging every few seconds. Affected users claimed that they could use the same third-party charger to wirelessly charge their mobile phones in the past. However, this problem began to appear after a recent firmware update.

It is not clear what update may cause this wireless charging problem in Galaxy S20 and Galaxy note 20 series. From the user's report, most cases only affect the ultra model. From the timeline of the event, the culprit may be the security patch in September 2020 or October 2020.

We learned that the affected users claimed that they had tried all methods, from restarting the device to clearing the cache and factory reset. This problem seems to be spreading, but so far, it seems to affect relatively few Galaxy S20 / Galaxy note 20 users. In other words, this problem may be widespread, but some users do not often use wireless charging or do not use wireless charging at all, so this problem has not been found for the time being.

Although Samsung's high-end machines have a certain market share, a system update will disable the wireless charging function. According to foreign media, more and more users reported that the wireless charging of Samsung S20 and note 20 failed after a system update.

These users are feeding back this problem in the official forum and other forums. When the mobile phone is put on the wireless charger, it is intermittent and can't be charged continuously. However, these users without exception did not use the original wireless charger. Xiaobian feels that, unlike the iPhone, which closes the use of a full set of accessories, Android phones should not pick these charging accessories. If they can't charge quickly, they can at least charge slowly rather than intermittently. Moreover, before the system update, wireless charging can be used at least.

They have tried to restart, restore factory settings or modify some settings, but they have failed to solve the problem. However, according to the update method of Samsung mobile phone push system, the update that will make you unable to charge wirelessly is not pushed in a large area. In fact, even if it is pushed, there are not many people who are really using wireless charging, and they are not aware of this problem.

This problem is mainly related to the third-party wireless charger. The firmware has stopped using with S20 ultra and note 20 ultra after some firmware updates. Not everyone has these problems, and Samsung's own wireless charger doesn't seem to have these problems.

One user reported that wireless charging was constantly interrupted every few seconds. The affected users also said that this problem had not occurred before using the same third-party wireless charger on the mobile phone.

There is currently no updated information about this problem caused by some S20 ultra and note 20 ultra owners. It is reported that this may be an update released between September 2020 and October 2020.

As one of the world's largest smartphone manufacturers, it's inappropriate to push down a system update without full testing and destroy the wireless charging. Perhaps due to the impact of the note 7 explosion in that year, Samsung did not dare to be too arrogant in charging. After the update of your mobile phone, is there any function damaged?
