I am on stock 8.0 after the update during a call the phone buzzed and made a loud sound like a siren. After the crash I used it and got message of abnormal restart. I decided to hard reset it. The phone buzzed for about 30 seconds at least and then booted giving me an error uDove to send to HTC. I sent the error and updated all apps to set up.

1. Since then whenever I wake up the phone with the fingerprint or open an app the current window goes white and gets minimised as an app would do. Or as if a pop up goes on and gets closed by an adblock (in desktop).
2. I noticed also lags in performance and battery drain.

All my apps are basic and from play store (major publishers and no games at all) With HTC support I used the phone in Safe mode and no problems where observed. I thought it was htc sense update that was causing the issues however it is not the case. I am lost and do not know what to do. The phone is annoying to use and 4 hard and soft resets did not improve anything.

I ran every check with the HTC utility and nothing significant was reported (all passed ok), During the following hardresets the bootloader gives error

Looks like partitions map is damaged (hard to read the photo). My educated guess is that you either get a RUU from HTC and let the phone recover everything fresh or unlock boot loader and install custom ROM.
Can you use superuser rights via adb in the HTC recovery mode?
It reads:
handle_cota_install: install cwpkg to /cache/cota/cwpkg.zip
handle_cota_install: install cwprop to /cache/cota/cw.prop
E:can't open /sys/class/power_supply/battery/capacity
handle_cota_install: can't mount /sdcard
E:can't open /sys/class/power_supply/battery/capacity

Could you please tell me what is RUU and how to obtain it? My phone model is this one https://photos.app.goo.gl/tgzt2ebSj1fdt5o29

I can read if I know what I am looking for thank you. HTC has not been very helpful online

HTC is sadly ignoring/abandon the U Ultra. Pity.

RUU is ROM Update Utility - it is an HTC format for update packages. Sadly, Oreo hasn't been made available by HTC.
Since (presuming) you are still under warranty (no unlocked bootloader etc.) I advise to hit the HTC service center and tell them that their OTA went wrong.
Alternatively I could only think of unlocking the bootloader and doing the fix yourself.

I as an update the phone is getting worse the more I use it. I screen blacks out for few seconds and then back to normal. Something like voltage issues. If anyone knows the UK repair service I would appreciate the details. They are not responding e-mails and chat is not helpful at all.

It is bought with UK plug so I assume it is the ones in UK?

Hello everyone, after buying a new device (huawei) and after 4 visits to the repair center my phone seems to be replaced with another one. unfortunately the battery was changed and it is worse than ever (after a hard reset it says it was last fully charged 223days ago.

I solved the problem by doing a hard reset and not updating the google app. My last reported version (installed by HTC) is 7.17.28.21.arm64 (my device is HTC U ULTRA but same problem). After this everything else runs smoothly etc.
I believe it relates to new features of the app that change completely how it manages the device

• Use voice commands while navigating – even when your device has no connection. Try saying "cancel my navigation" "what's my ETA?" or "what's my next turn?"
• Weak connection? If your search fails, the Google app will deliver you results once you regain connection.
• Troubleshoot connectivity issues with more helpful error cards when your search fails because your device is offline
• New customization options available for cards in your feed
