Hi,
I wonder if you test your ESET Mobile product with cheap Chinese phones. Because my Umidigi A5 was left completely unusable after enabling the paid options in ESET Mobile. And I do know this Mediatek based phone has some irks (eg: Google Play Books crashed with an update delivered by Google around mid-2020, it started crashing in a loop, non-stop, and since Play Books is one of the preloaded apps, there was nothing I could do other than seeing this app crash in a loop. I had to find the Google product manager and email him directly. He told me "well, you seem to have identified a very obscure bug of this particular Mediatek SOC related to the bitmaps rendering"). Two months later they issued an app update that fixed the issue. I never knew what the "obscure Mediatek SOC bug" was.
Back to the ESET topic... Let me explain: I had the ESET Mobile app installed, with the freeware features. The last scan performed was mid-December 2021. This Umidigi A5 had its last software update by March 2021, so I knew it had surely several exploitable holes (those that are not patched by Play Protect).
Only recently I noticed that when I selected an ESET full scan manually, my phone would freeze a few seconds after the scan started. And by freeze I mean, COMPLETE LOCK UP, even the time at the top would freeze. I blamed it surely on the old SD card in there that is 4 years old. "Maybe if I remove the SD card it won't luck up". I thought. -I was wrong, but more on that later-.
Since Play Store informed me this week that it had disabled an app that was "dangerous" (speedcheck.org by Etrality Gmbh) because it can "steal data and control your device" - I got a bit paranoid and decided to pay and enable all the security features. It worked, until the first phone reboot.
Now my phone crashes every single time shortly after the launcher appears. About 30 to 40 seconds after entering my PIN. My smartphone is basically unusable. Luckily I was able to do some things in the first few seconds when the phone works, allowing me to move accounts and 2FA codes to another device. But others, I wasn't so lucky.
I'd like to know if your regular tech support can provide any help in situations like this -I worked at tech support, I know how things work, first they walk you thru all the known "known solutions" flowchart and only after a while your request is escalated to "tier 2"... or if it's better to contact your research labs directly...
I'm not the average user, I'm proficcient with adb.exe, and I'd like to get to the bottom of this, what is causing the crashes and if this was related to the malware that play protect recently disabled (check it out yourselces, https://play.google.com/store/apps/details?id=org.speedspot.speedanalytics is gone from play store) or some kind of incompatibility between the Android 9 in the Umidigi A5 and your software.
Thanks in advance.
