    I was seeing this issue every day since I got the phone (3 weeks) for the last 3 days it hasnt been happening the network switching has been working as expected (TMO converted OPO7P 9.5.8). The ONLY thing I did diffrent this time I converted back to INT was once I flashed the 9.5.3 I did a FULL local flash to 9.5.7 and then OTA to 9.5.8. TBH I think something was changed/fixed on the back end

    I am on Intl software but went from 9.5.3 directly to 9.5.8. Please keep an eye on if it drops bc mine is still dropping.

    if you do go into airplane mode because the updater will try and do the 9.5.8 ota so flash the 5.3 wipe cache skip setup airplane mode, then copy the full 5.7 over local flash, wipe cache then ota 5.8 that's how I did it maybe it helped maybe it didn't but that was my process

    I can confirm fast roaming did nothing. I just dropped WiFi on a call and it went to VoLTE, which does me very little in my area.

    OnePlus has reached out to me to gather logs and info for them. Stay tuned...

    I am also curious...for those of you that are having this issue have you converted to the Intl software or are on the TMO software.

    If you are on Intl version did you go from 9.5.3 to 9.5.8 or did you do 9.5.7 in between.

    If anyone wants to send me info I will begin to collect it and provide it to OP. Ping me at stevefxp@gmail.com.

    original TMO
    TMO firmware no VoWiFi issues
    INT convert 9.5.3 issues
    INT 9.5.6 issues
    INT 9.5.7 issues
    INT 9.5.8 issues
    Convert 9.5.3 then ota 5.7 and ota 9.8 issues
    INT 9.5.3 to full 9.5.7 then OTA 5.8 no issues for the last 3 days
    all on my GM9115
    full cache wipes between all upgrade/flash

    now I didn't stay on TMO firmware long so that may be a res herring. Normally it takes a day to start acting funny just as a side note as well

    9.5.7 resolved the issue fully for me, haven't had any issues either with 9.5.8

    if they had the same camera updates as the INT firmware I would but it isn't even close to the same fixes and improvements the TMO firmware is still like 9.5.6 INT

    why not download the APK for the camera? the 9.5.7 T-Mobile update was the same camera update as the international, just a different APK version number due to the software difference.

    not even close, the nightscape function is totally different and the cam popup for video when locked isn't in the TMO .5.8 it still pops up in my pocket. I did a side by side myself with the same scene TMO 5.8 and INT 5.8 and the pics are way off and have ALOT more noise than INT version

    I didn't say the 9.5.8 camera updates, I stated the 9.5.7 9.5.8 for the T-Mobile version was the security update. the .7 was the overhaul of the camera. and as mentioned previously, why not just update the APK for camera from APKMirror?
