For £36, you can assume a basic standard, but nowadays we must require a working keyboard or some USB keyboard with wi-fi or USB connectivity. The decision to buy and try may be easy to do, but getting a refund, later on, is not as simple. A local High Street store is more likely to refund your money yet not be able to return any files to you or your stored personal data for various app logins. So don't save login details in the first place.
The user interface and various setups may have default settings that aren't suitable for our needs.
The downloading of an app may require the security setting switched off temporarily but we must switch to the secure setting afterwards. We know of app limitations, but is this a locked device stopping us from storing app data also on to some micro SD card to help the internal SD card to accept a few more apps later?
Remember that it's the storage limitations that will affect us in loading apps and antivirus and Google apps take priority. After these, how much storage is left? Usually, we need a minimum of 500 MB just to stay operational, yet if we download videos or large files, these use up storage till we transfer these to the micro SD card instead. Can we edit the download path eg external_storage?
Without technical testing, these Android devices aren't worth worrying about. They rely on app creators who keep updating what used to work to something that's iffy from then on, some not allowing us to choose to return to the previous version that worked.
However...
I'm of the opinion that the tendency now is just to throw our money at the wall and hope for the best, get average results and still gamble on the next device.
From experience with AEI in 2016, we can't trust our data or our return by Royal Mail to be confirmed by the makers or the sellers. We can't prove delivery unless signed for and even then the companies involved don't always care about customer needs, expectations or the upholding of the Sales of Goods Act for each new transaction involved.
If forced to buy locally, then, at least, we get some response at the counter or from the Manager, but repairs are unlikely and data security is impossible to prove one way or another.
