No GAPPS? No problem.

All of that will not help you in the slightest if the chipset vendor baked in spyware. Mediatek is the master of the cheap chipset, and they have compromised the OS in both Russia and the US with dozens and dozens of OEM devices.
[BLU] phones were regularly sending bunches of personal information to servers in China: text messages, call logs, contact lists and so forth. After more investigation, it came to light that this was happening via a low-level piece of software called ADUPS.
When Google had previously updated its systems to check for ADUPS, MediaTek (they make the chipset in millions of low-end phones) simply modified their system software to evade Google's checks. Nice one MediaTek!
And in not disclosing that it is using both, it opens many, many security holes on older platforms. Furthermore, we don't know how much work is being done by the local Webcore, and what sort of hostile traffic that Presto might send to it.
Avoid this browser in those cases. It is not safe.
We should all be looking at Tor at this point.
One common reason is 3rd party code, which they may have licensed and do not control or own.
Alternately, the code may still be seen internally as useful, which it is with Opera Mini. It is still used to generate revenue, and may contain what Opera considers to be trade secrets that give them an advantage over a competitor (i.e. Amazon Silk).
If you set the "data savings" option down from extreme to high in the settings menu, the scanner at ssllabs.com will report Webkit, not Presto. The Webkit version will be whatever is included on your device (Webcore). If you are running KitKat or Jellybean, you will see lots and lots of security problems with your Webcore, since they date from the end of the XP era, and haven't been updated since.
I believe that Presto would be installed at Opera's corporate systems, and it would feed a compressed stream to the Webkit used by Opera Mini.
Opera Mini could not be so small and include both a complete rendering engine and links to Webcore. They essentially cheated.
Let's not forget the effect of helicobacter pylori bacteria on ulcers, they are in general held to be the main cause these days.
I have another theory about the beneficial effect of aspirin, caffine, etc. We evolved with them. Our diet was rich in salycilates and chemicals similar to theobromine or caffine. They came from the plants we ate, some of which were mildly toxic and which we evolved to process to the point that we became dependent on some of their effects. There are a lot of things in the primitive diet that modern people don't eat much at all, like acorns which had to be soaked to remove alkalai and tannin.
If this is the case, taking aspirin and drinking coffee or tea replace substances found in a more primitive diet.
If this was a drone and was just using the mobile frequencies for communication, it would probably use an off-the-shelf cellular modem module to communicate normally over the cellular network. A special testing authority from the FCC would not be necessary.
If all else fails, lower your standards.
