well I have moved to lineage os with pie firmware and the slowdown has persisted
it means that the lineage os has the same device health manager also, so just try deactivating it and see if it helps. in my case after deactivating it my op3t is just as fast as it was with oreo stock. before it was noticably lagging. i am sure oneplus will release another update to solve all the issues we have. its funny that the google pixel was slowing down because of a similiar app which is called digital wellbeing. but in the case of oneplus its "Device Health Manager". the app is throttling the cpu for some reason.
also because "Device Health Manager" is overloading the cpu it consumes a large amount of energy therefore depleting the battery as well. so since deactivating it my battery life has been excellent as it was on oreo and the performance matches the oreo stock rom also.
Someone have "Device not certified" in the last option of de Settings in Google Play? I can't use Google Pay if this option not return at previous status
not able to.see the caller ID during incoming calls,
How to stop the google adds comming after P update?
Please help. I tried everything.
Remove the app that's serving them, it's not an OOS issue.
After upgrading my phone to oxygen OS 9.0.3, my phone hangs a lot, have issue with camera whenever try to make video call. Application like google maps keeps on restarting. Lots of lags...no happy with new os
In general, after factory reset, Pie looks nice on my OP3.
Nevertheless, I have no idea what has happened to Camera app?!?!
Compared to previous versions, half of the settings and options are missing.
Is there any info about what's turned on, off, image quality, slow-mo, image stabilization modes...?
I was trying CB1 and CB2, OS 9.0.2 and 9.0.3. these builds was overheating my OP3 (lags till overheating fuse turn off phone). after one week on these builds home button stop scaning fingerprint or home button stop works.
Pie is nice, but useless for me. I'm back on Oreo and everything is fine, just annoying OTA 9.0.3
I was updating from 5.0.8 to Pie with full factory reset after update.
I hope next Pie will be better cooked
try modded goggle camera from XDA. I posted link here
I got the same on my 3T and the phone is not working properly now
I have disabled health menager and seems to improve a little but still lags, every now and then specialy on Twitter....
Did you do a factory reset as well, if not then i can guarantee you that the phone will lag.
one plus 3t battery draining very fast after Android pie update.
Anyone having issue with ALL of the messaging apps? When I'm on mobile data, I can not receive or send any message via Whatsapp, Facebook messenger, Line, Telegraph, etc. But I can still call, browse internet, play game, tweet - mobile data works for everything except messaging app.
But if my phone is on wifi, everything works fine. Anyone having the same problem since Oxygen update?
don't you think factory reset will restore full system partition including health service in active state
force stop google play, wipe google play service data and reboot..done
I have installed Oxygen OS 9.0.3 on my OnePlus 3T.
I am not able to change ringer volume with volume buttons. Volume buttons only adjust media volume.
