[PN7221][Android16] Repeatedly swiping the card quickly may result in NFC becoming unusable. The following two NFC firmware versions were tested, and both reproduced the problem: Version 1: 3.2.4 Version 2: 3.2.6 The log has been uploaded as an attachment. If a problem occurs, killing HAL will restore normal operation. Re: [PN7221][Android16] 反复快速刷卡,概率出现nfc无法使用 I've tested it after upgrading to version 03.02.06, and the problem can still be reproduced.

The log shows FW: 03.02.C4 , which is a temporary version. Upgrade FW to the latest version 03.02.06.

The log showed the same issue as a freeze triggered by a quick card swipe. Please see the log "20261020_194057_F802E693J0065.zip". The symptom is that NFC stops working after the screen is off. Rapidly and repeatedly swiping the card is just my method for reproducing the problem. Re: [PN7221][Android16] 反复快速刷卡,概率出现nfc无法使用 Hello
Based on the logs you provided, they all show timeout errors, so your current situation is caused by the card reading interval being too short. It is not recommended to read the card so frequently. Re: [PN7221][Android16] 反复快速刷卡,概率出现nfc无法使用 I'm refreshing slowly, and haven't been able to reproduce the issue yet. Re: [PN7221][Android16] 反复快速刷卡,概率出现nfc无法使用 The fastest refresh rate is about two refreshes per second, and the average refresh rate is about one refresh per second.

It looks like it's stuck and can't recover, trying to read the card again. "Repeatedly and quickly"—what's the approximate frequency? Would this problem disappear if it were slower? Re: [PN7221][Android16] 反复快速刷卡,概率出现nfc无法使用 Hello @zhangkai
Please apply the patch as email!

kelly Re: [PN7221][Android16] 反复快速刷卡,概率出现nfc无法使用 I repeatedly swiped the card for 20 minutes, but the problem hasn't been reproduced yet. Re: [PN7221][Android16] 反复快速刷卡,概率出现nfc无法使用 The system freezes when I swipe card 1 first, then card 2. This issue has been confirmed to be unrelated to the patch, as the same phenomenon occurred before importing the patch. Re: [PN7221][Android16] 反复快速刷卡,概率出现nfc无法使用 Even after importing the email patch, the problem can still be reproduced, and even faster. Test with the following steps, and it will definitely be reproduced: 1. Swipe your card first. 2. Swipe card 2 again, and the system freezes. 回复: [PN7221][Android16] 反复快速刷卡,概率出现nfc无法使用 Hi, any new developments on this issue? It seems that the problem mainly involves alternating between SIM 1 and SIM 2, which can trigger a freeze.
