I'm not google. But, those affected by this issue should raise their voices and ask for free battery replacement and/or get discount for an upgrade to the pixel 8a or a free 7a upgrade.
This is a safety feature since there's a serious risk of battery overheating. I would be careful and accept the update or get the battery replaced by official google. Unless, of course you like to live a dangerous lifestyle.
Considering the precedent and the new battery ageing limit features in pixel 9a its unlikely. Going forward you will not just lose capacity but also lose charging speed. Atleasf in newer pixel phones.
Solid explorer works with all android smartphones all the way from android 4.4 kitkat to android 15 and perhaps also the upcoming android 16.
In any case you will have to contact this wallet app developer since you cannot provide more information and won't get useful answers on this community.
Maybe, the issue is with your wallet app? Have you tried other pdf files on your phone. Or using a file manager like solid explorer to see if it can open the PDF file?
Barring that share the phone, Android version and possibly the PDF file being used in question so others can test on their phone? If the PDF file contains sensitive data redact it using a desktop pdf app.
I have a curved smartphone with thin bezels. Unless, you use the phone without any case. Its fine. The touch rejection on my current phone is good so accidental touch has never been a issue. On the other hand the immersive views make the experience good.
The difference would probably be €50 more for higher storage if not higher. Still, I can't see this being a deter for many people.
You can install LineageOS, \E\OS.
Works fine on my android 15 device. Just need to provide the all files permission at the prompt.
I use one because it had one in the box. Otherwise, I would've purchased one since the back is prone to scratches and degradation. It also adds a level of protection to the phone.
