[Samsung Galaxy S7 Edge Questions and Answers] shah22:
Hello respected members, I yesterday flashed that btu oreo rom through odin on my S7 edge G935FD , all went well and phone is working good, but in recovery there are these type of messages, I have seen on forums that many people are experiencing this recovery issue, is there a solution for it? Apparently they don't effect phone in anyway or cause any issues, but still why are these messages showing ? I am just worried about bootloops. Those messages are :

(fail to open recovery_cause(No such file or directory)

Reboot Recovery Cause is [UNKNOWN])(This is still showing in ERG2)

No Support SINGLE-SKU

File Based OTA

Supported API: 3

MANUAL MODE v1.0.0

Sucessfully verified dmverity hash tree

E:Failed to clear BCB message : failed to find /misc partition

Issues updated (OREO ERG2) :

1. First of all those weird "failed to find misc partition" messages in recovery. Don't know if they cause any issues but they are annoying. No bootloops or any other issues though. Happening since first oreo release of 1st May. (Fixed in ERG2 release).

2. Can't go into download mode anymore from recovery by using option " reboot to bootloader ". It just reboots the phone normally. Happening since I flashed the first oreo release using odin. (Still in ERG2)

3. If phone battery gets to 0% and discharges completely, then when plugged in the charger it goes into recovery mode instead of that charging screen. I used power off so that it exits recovery and goes into charging screen, but it again booted in recovery, when I selected " reboot phone " option it turned off and got in charging screen.. strange thing, I never experienced this on nougat, its happening since the first oreo release. (Still in ERG2)

4. Cell standby drain not that high after the 18th may btu update, but still high before it was 33% and screen 20%, now its 2-3% above screen battery usage. Happening since first oreo release. A note here that after flashing 18th may release I think battery life is good and SOT is somewhat same as last nougat release.. (Still in ERG2 release but somewhat more less.. but battery life on ERG2 is a little less than previous builds..)

5. Phone rebooted randomly before 18th may update, now after updating it seems to be fixed. Note that I experienced random reboots but no bootloops or other issues etc. (Already fixed)

6. Fingerprint scanner issues:

Fingerprint scanner becomes unresponsive randomly and I had to unlock using password. This is occuring from approx december or january security patch update and still isn't been fixed in latest oreo. This issue has surely increased in oreo, and now it happens more often and is very annoying to the point I disabled fingerprints.. (still in ERG2, for me, don't know if its hardware related)

Also in oreo, fingerprint requires more time to open the lockscreen, some 1 sec delay approx. Can't say if its requiring more time to match the fingerprints or its taking more time to unlock the lockscreen..

Note : I didn't experienced any connectivity issues in bluetooth, wifi or mobile data..

Some times I had to re-select default network mode for my sim in settings if internet gets hanged and don't works, but it happens very few times and changing network modes in network settings will instantly solve it, and it was also happening on nougat before. And didn't increase in oreo at the moment for me..

Also to tell you all, I flashed back last nougat release for my region successfully, but it looked too much slower and laggy as far as I remember before flashing oreo btu, maybe its because I got accustomed to oreo ( which is faster than nougat ) or maybe downgrading caused some issue maybe. But I don't think downgrading should cause performance issues. Also when I downgraded on nougat I couldn't go into download mode from recovery mode using option " reboot to bootloader " and it reboots to normal mode. I don't remember this, because always this option worked in nougat for me before flashing oreo. Don't know what's the reason but not a big deal. Also I didn't tested after downgrading about fully discharging battery and then putting phone on charger whether it goes in recovery or normal charging screen. Btw those fingerprint issues are a real pain.
