Just got the tmobile android 12 update on my Oneplus 9pro global version and its causing issues
I have the global version of the one plus 9 pro and have always stuck to tmobile firmware cause I need wifi calling/texting. Just got the android 12 update today. Now my phone thinks its always charging even when not plugged, battery drains twice as fast, no 5g, no wifi calling/texting.Also my bootloader is unlocked but the phone is not rooted. Anyone else having these issues or have any ideas on how to fix them?
How to flash back to OS11 on T-Mobile OnePlus 9 Pro (or any OP phone).
I had updated to OS12 on my OP9 Pro and I hated it. There are now too manyuseless features, not to mention a few of my most used features disappeared (such as the seconds on my clock in the notification bar, and the quick features by long pressing HOME, RECENTS, & BACK buttons.) So I used the MSM Download Toolkit to flash back to OS11, and I am going to use 11 until T-Mo releases 13. Here is the complete list of OP devices and their respective MSM Download Toolkit(s) associated with them. *Remember to always use the toolkit for YOURdevice model -for they are not interchangeable. You will get a failed result EVERY TIME.* This also works for BRICKED OnePlus devices. https://onepluscommunityserver.com/list/Unbrick_Tools/ For thespecific T-Mo OP9 Pro device, I have the ZIP file available to download along with step-by-step instructions on how to Flash Back to Android 11 on OP9 Pro - inside of my Google Drive folder : https://drive.google.com/drive/folders/1PbVwsUqW8Zh1sJLgl4Uf-YMkzvr8PJt8?usp=sharing
Voicemail notifications and OnePlus 9 Pro software updates
Last couple of times I seen I missed a call and never heard it ring. I did fix that issue why sound was turned down not sure. I discovered those missed calls did leave voicemail and that notification is not showing up. Came here to investigate and found issues with the software for the phone OnePlus 9 Pro. For the voicemail: When a voicemail is left there is no notifications showing for voicemail just a missed call. I have tried different things to get notifications to show but nothing has worked and went to the extreme and uninstalled the T-Mobile VVM knowing that I can always reinstall it later. That did not work, and yes restarted the phone several times and used the house phone to leave messages. If I know there is a voicemail I can retrieve and found them calling voicemail or using the VVM, I just want to know there is a message. Read where others have had this issue but could not find a simple way of fixing this issue. For software update: Question on this is if there is an update and T-Mobile does not provide it as quickly as OnePlus can you download the new update through OnePlus website? I am there and it goes into detail how to download to computer then to phone. Not something I plan to do at this time since I am not having any issues with the software unless it deals with the voicemail. Just reading where others have had issues with a new update that has caused them issues and the update is months older then what is available and thought to ask for future reference. Only have the phone less than a month and so far everything has been fine for me till I discovered notifications for voicemail not showing.5G Network not working after Android 13 Update OP9
My OnePlus 9 5G just got updated to Android 13 automatically. Unfortunately, this update mess up my phone because now my phone isn't working. I can't receive or send calls, signal bars goes on and off and never connects to 5G. Please, If anyone knows how to fix this let me know.OnePlus 9 system memory at 96gb
I have 3 OnePlus 9's and they are keep going higher and higher in the system memory. One of them is at 96gb, the other 2 are at 64gb. We did a factory reset and that seemed to help for an hour or so then started to creep up again. How do we stop this from happening. It eats up all their memory space.recommendations before upgrading le2127 to Android 12?
I've heard horror stories about Android 12s roll out. I'm afraid I'm gonna lose everything or have a expensive paperweight that won't even be able to operate while being multiple months behind on security updates… I did backups, which I don't trust... Which is why I also just copied the entirety of the internal storage files onto my computer just in case. I always dread when the OS upgrade comes around because settings get changed, backgrounds get lost somehow, notification alerts change, and then I gotta go through every page in the settings menu to get things close to how I had it before the upgrade… If this upgrade is awful, is there anything I need to do to be able to switch back to Android 11 and have all my settings intact? Or is it just a pipe dream for that to even be a possibility?
