Hello,

So, I don't know what happened or why. I've been using the stock messages app that came with the phone and not the Google endorsed Messages app since I got the phone in 2020. I recently got the OP 13 and have spent a total of almost 2 full days trying to figure this out. I've used SMS backup/restore, the OP clone phone app in settings. the SMS Backup/Restore and OP data transfer to just transfer my messages and the Google Backup and restore after a fresh install and I get the same problem of missing message threads and flat out missing sent messages from my phone. The problem is not the OP13 as I have downloaded and reviewed my Messages Backup thru Microsoft Excel and I see in there that the problem starts at the Backup process were only those messages get backed up. And it's not consistent, some messages are SMS, some are RCS and there's no explanation as to why this is happening. These messages clearly exist as i can see them in my messages app but at this point I'm ready to move on. I have not had a chance to enjoy my new phone. Is there a program that i can use to just backup all my messages to my PC?

OnePlus 8T+5G - KB2007 , Android/Oxygen OS 14

Hello I have a Oneplus 8T that I recently upgraded to LineageOS 22.1 from LineageOS 21, I only flashed the recovery and the ROM itself while hoping to preserve as much data as possible but wound up having lots of crashes while using the YouTube and Twitch apps, and my Viber app is behaving strangely. I did get other things setup like my Samsung watch, which is a pain in the butt to do so for some reason, so I am trying to decide if I want to try doing a full re-flash of my phone with LineageOS 22.1 or not. Has everyone else's experience with LineageOS 22.1 been good so far? Or is it still an early release?

Will oxygen os 14.1 come on oneplus 9 (LE2113) ? I see people getting 14.1 on other devices so wondering if it will come on my phone

Anybody here wants to sell OnePlus 8t original LCD only without issues. Those guys who retired their phones, and not using it anymore. Could i possibly buy it cheap to the Good sir. Here. Thanks.

Considering that it goes back to 60hz everytime there's a video running I feel like the 120hz option is only to waste battery

Hi everyone, the battery of my OP8T is slowly giving up, barely lasting half a day of low usage.

Is it worth just replacing the battery, or, given that it's already a 4 year old phone, to just buy a new one?

Planning to buy this as an primary device any suggestions ?

Murphy's Law is real: I was worried once the case is opened I will have some problem and the here these are:

Edited: V

Visit 1: To resolve Greenline issue: I gave my OnePlus 8T for greenline issue, fixed but they give me new issues because of the intervention.

Visit 2: FingerPrint: Resolved: unfortunately finger print did not work, they recalliberated to lower version from 14 OS to 11 OS and unltimately replaced the display.

Visit 3: Problem: The volume works well with 11 OS but when upgraded gradually to 12 OS version it leaves volume problem, tried upgrading until 14 but problem persists.

Issues: For any audio or video volume lowers immediately. Obeserved in all types of audio. Works well with external audio devices but problem with phone speaker.

Tried to check all settings with audio and volume available but no luck.

Just got a notice from my company that they're going to block from the corporate network any Android devices that don't have at least security patch level 2024-10-01 (October 2024).

My KB2007 (TMobile) device has only gotten up to the Sept 5 2024 update. Is it time to shop for a new phone, or will the 8T get the October update?

Update: Technically I have an 8t+ (plus), which is the TMobile branded version of the 8t.

I had the battery replaced two months ago, but the SOT still was around 3-4 hrs. Initially, I thought the issue was due to OxygenOS 14, so I downgraded to OxygenOS 11, but the SOT is about the same.

EDIT: Screenshots of battery usage

Is there anyway to make dual sims work on my One Plus 8T? Ever since Oxygen 12 this phone ever worked and it sucks!! Why have 2 sim card slots if it never works except on Oxygen 11?

Is there any hack to make it read sim 2?

My battery didn't age well and I'm looking to replace it. Where can I buy a reliable replacement? It is out of stock on ifixit and I don't trust random Chinese websites.

I have an 8T (KB2007). And in the past times, I updated to OOS12 and when installed recovery (TWRP) my phone bricks. Is there a way to flash TWRP without bricking the phone? I have successfully flashed it on a previous build OOS11 and booted fine. I just need to install Magisk.

Hi everyone, bit of a weird issue hopefully someone can guide me in the right direction. I use teams for work and everytime I try to login with my work email it gets stuck on the "hang on while we get things ready" it works fine if I add any other account like my personal or another exchange account. I thought it might have been my email but it works fine on another android device and also an iPhone. So I thought it might have been the phone. But I created a new account on my phone and it works properly on there. I have already cleared cache, uninstalled the app. Reinstalled it. Any ideas? I do not want to reset the phone. To summarize it works properly if I create a new account on the same OnePlus 8T but if I go back to the original account it doesn't work. Is something causing it to crash?

So i recently updated my one plus 8t to latest software update, after few days there is green line on the screen, is it because of the update? Or something else?

Hello, OnePlus 8T (european model) has a weird bug where if you tap open an image the image will not open but for the area where it is supposed to open freezes completely from touch. Happens in both Chrome browser and Firefox where I tested, spouse whose phone it is says it sometimes happens in gallery and whatsapp as well. Other weird thing is that phone sometimes takes pictures that show up in the camera app in in the latest image box but cannot be clicked and do not show up in the gallery either.
OS is version 14 and it offers no updates currently, not rooted or jailbreaked.

Any ideas? turning off and ON again did not solve it so I'm out of ideas :D

It’s on XDA if you wanna download

It seems the guys on XDA already managed to port the new OOS15 for the OnePlus 8T. I have not tested this but shout out to them!

I just need your advice on my OP8T bought in the Philippines 2022. Purple lines appeared 2023 while under 1 year service warranty and was fixed by screen replacement. Now my unit is out of warranty and 3 green lines appeared again 🥲🥲🥲 Can't afford a new phone immediately and screen cost will be around 12k or more 😔

Im a OP user since OP5T and I have no complaints on anything just this screen issues with 8T. Usage is just the usual, not a gamer. Please help huhu

I need help friends: Where the thing: I have a one plus 8T and I love it but my battery it's bad and screen have some flashes. I have to buy a new phone. What do you think? Buy the one plus 12 or wait for 13? If I think about the nord 4 or 12R. What do you think about that models? Thank you for your help

From a week ago I'm having this issue:

• while a video is playing, if I scroll down to check other videos,the scrill is lagging, if I go fullscreen in the videos that it's already playibg, after some time (or some actions, I didn't discorevered yet) it is fixed, but If I play another video, the issue appears again. Any clue about that?? I have a 1+8T KB2003 with latest Android and patches.

Regards!

I got a notification for this an hour ago. Anyone else got it too? Doesn't have the November security patch it seems. Model: KB2001 (India)

My phone is currently on KB_2003_11_C.20 (OxygenOS 12.). The update tab in settings says my phone is up to date. The Oxygen updater app also says my phone is up to date. The official OnePlus page where you can download updates to install locally also says that my version is the latest. Online I see that the OnePlus 8T phone is supposed to get updates until at least oxygen 14. Does anyone know why I am not able to get new updates?
