S20 apps crashing with One UI 5.1 update

[gingerwinger]

My S20 was working perfectly until I updated the software to One UI 5.1, now all the apps crash, phone freezes and reboots. Very annoying! Have cleared cache by going into system but still does the same. Any ideas as what to do next as this update killed my phone!

Thanks in advance

Hi @gingerwinger  Have you just updated to One UI 5.1 and was this by official means?   If wiping the cache partition has not helped you could try a Factory Reset ,even if some view it as a bit of a hassle. Ensure you back up Data before doing so.  However the device will soon stop receiving security updates and will thus be more vulnerable.  https://www.gsmarena.com/samsung_galaxy_s20_series_extended_software_support-news-62381.php

Usually Clearing the Phone's System Partition Cache Files Section does help but I see you've already carried this out. 

Are you able to ask a question via your Samsung Members App. 

As @JAMES4578 says a Factory Reset 👍 is an option or go through https://www.samsung.com/uk/support/repair/ 

A hard reboot may help > How-to-force-reboot-your-samsung-galaxy-smartphone/

I have the exact same problem with my M23 5G 😞  tried factory reset, but it keeps the faulty update. So all those npc advice are useless. There is a hard issue within the code of that update.

Since the phone is not stable and crashes all the time, the only way to get this possibly fixed is to use a manual bootloader and put an older version of one UI on it. ( thats what I assume, please proof me wrong!)

This will be my last Samsung device. I am sick of those corpos.

After performing any major software update, it is then advised to update all of your apps as well. Especially with this being an older update, many app developers will have patched any problems with their apps by now. Make sure to check both the Galaxy Store > 3 Lines > Updates. As well as the Play Store > Tap the round icon in the top right > Manage Apps and Devices > Updates Available. 

If you continue to encounter app crashes, latency and reboots, try your phone in Safe Mode to rule out a third party app interfering. Swipe down from the top of the screen with 2 fingers > Tap the Power icon in the top right > Long press Power Off > Tap the shield and the phone will restart. 

Run the phone in Safe Mode for a couple of hours, using the apps that are available, and monitor the performance. Safe Mode is a handy tool that disables all third party apps, so if this behaviour stops occurring in Safe Mode, this confirms there is an app at fault. In which case, you would need to uninstall your downloaded apps one by one, until you find the culprit. Once found, either keep it uninstalled, or contact the app developer for a fix.

Thank you all for your help, unfortunately nothing has worked. Even crashes in Safe Mode. All Apps updated. Cleared cache and still crashes. Any other suggestions before a have to reinstall a previous version?

It's got so bad now that I unplug the charging cable and it crashes and freezes. This is a software issue and needs to be fixed ASAP!

Well I had enough of my phone restarting every minute from 3am in the morning until 3pm so I brought a new phone. It was getting so hot too! Took the sim out to put in newly purchased phone and old phone hasn't rebooted once or got hot since! Wondering if this is a deliberate ploy from Samsung or Vodafone 🙄🤔🤫
