Rel V7 feedback:
1. Power charging is slow, and power consuming is fast.
2. Heat generating is still a little severe.
3. The app in the back can't be locked, every time to clean back and clean all the apps. Hope to add a lock to lock some apps which are user choose.
4. Whe Wifi disconnect, can't auto connect if the Wifi is back.
5. NFC can't work.
1. Charge time is slower than before and power consumption is a bit high, but is not that bad.
2. Heat up, a little, not that bad.
3. Asked before, 5.1.1 issue, not his problem. Just need a working around solution.
4. No problem with WiFi, tested and can reconnect automatically in China, Hong Kong and Taiwan.
5. No problem with NFC, works with my camera apps and Octopus card in HK.
But started from V6, it happened few times that the phone slowed down to almost no respone and back to normal after clean up all apps in background.
WiFi can reconnect automatically in Hong Kong, but in China, Saved networks shows "No Internet Access Detected, won't automatically reconnect."
I go to China every weekend, never see this when using WiFi connections.
It may due to Google service blocking, I do add a CM account and that have been reported help solving the “!” marking issue, you can try.
Oh, I use fqrouter in China to get access to Google services and blocked web access.
Try this:
Delete existing network and reconnect.
I have the same before when upgrade from v5 to v6, delete and connect solved the problems. Hope this will help.
sorry, in V8 camera not work
flash this zip without wipe
cm12.1_V8_camerafix.zip
Anybody can confirm CDMA Traffic is working or Not???
CDMA traffic can use in V8.
Hi,
All cm12.1 users, i would like to check if any apps or modification can be made to let phone show incoming call from sim1 or sim2 before answering the call?
Kindly share if you have the method, thank you very much.
Thanks for adding more volume steps into V8.
I do find a small bug about receiving call volume. Every time when I receive a call, the phone volume turns to max and I have to turn it down few steps . I also find there are only 6 to 7 steps in voice call volume control.
Just baseband_354 share.
Feel a little fever, hoping to improve. Support your work
Rel V8 feedback：
1. NFC can't write in data.
2. The compass accuracy is not good, it has a little deviation of direction.
3. Wifi signal is not stable.
4. When using, it's a little hot in the back cover of phone.
5. Network speed in the status bar calculates too fast, please change slower( 1 second calculate once for example ) or let user set the frequency.
6. The search in the Apps setting can't work.
7. Please add a setting to allow user to close multi-user function.
8. I'm left-handed user. Please add a setting in Buttons to allow user to exchange physical keys function( exchange menu button and return button).
Thank you for your work.
