## Resolved Issues

**Table 3** Resolved issues

| Issue No. | Description |
| -------- | -------- |
| I8WP8M | Create a large folder by moving an application icon on the home screen to overlap with another application icon, and then move an application icon out of the folder. Repeat this operation. Five minutes later, a total of about 25 MB memory is leaked on the launcher, that is, a 673.68 KB memory leak for each operation. |
| I9A9NO | Repeatedly touch the upper right corner of the SMS application to create an SMS message and then touch **Back**. When this operation lasts for 5 minutes, a total of about 50 MB memory is leaked, that is, a 341.33 KB memory leak for each operation. |
| I8TM99 | There is a low probability that a C++ crash occurs in libbtframework.z.so of the softbus_server thread of the softbus_server process. |
| I90A2N | There is a possibility that app freezing occurs in the com.ohos.systemui process because THREAD_BLOCK_6S is stuck in the libeventhandler.z.so stack. |
| I9A089 | There is a moderate probability that system freezing occurs in the foundation process due to SERVICE_BLOCK. |
| I9CGOZ | There is a high probability that app freezing occurs in the com.ohos.camera process because THREAD_BLOCK_6S is stuck in the libcamera_framework.z.so stack. |
| I8QH9S | There is a low probability that a C++ crash occurs in libnative_appdatafwk.z.so of the os.settingsdata thread of the com.ohos.settingsdata process. |
| I963TL | There is a low probability that a C++ crash occurs in libark_jsruntime.so of the com.ohos.mms thread of the com.ohos.mms process. |
| I97U6G | There is a low possibility that app freezing occurs in the com.ohos.certmanager process because THREAD_BLOCK_6S is stuck in the librender_service_client.z.so stack. |
| I98KIG | There is a low probability that app freezing occurs in the com.ohos.camera process because THREAD_BLOCK_6S is stuck in the libcamera_framework.z.so stack. |
| I96CJL | The networking between mini-system devices fails. |


## Known Issues

**Table 4** Known issues

| Issue No. | Description | Impact | To Be Resolved On |
| -------- | -------- | -------- | -------- |

| IA5I3D | There is a low probability that app freezing occurs in librender_service_base.z.so due to THREAD_BLOCK_6S in the com.ohos.smartperf process. | This issue has no impact on users. It occurs during application testing. The application may crash if the test time is too long after developers touch the floating ball to start the test.<br>Workaround: Terminate the background process and open the application again. | June 30 |
| IA4G47 | There is an extremely low probability that a C++ crash occurs in libhcodec.z.so of the av_codec_service thread of the av_codec_service process. | This issue has no impact on users. It occurs during application testing using the Wukong tool. | June 30 |
