Hi Wooly,
Good to hear you're thinking of getting
ExplorOz Traveller to load
EOTopo maps. If buying a new Android tablet - yes other than checking it has a GPS to enable offline location
services, the single most important feature you want is good Processer and Memory (ie RAM).
I've recently noticed that some new Android devices are being sold with very low RAM (to attract the low end market) but these devices are not designed for multitasking - ie. using multiple apps at once, or using apps that run in the background, so they will crash instead of hold
information in the background. Be aware that mapping and navigation apps are quite demanding on RAM so don't opt for the cheapest device. If you only spend $200 you'll not be getting a quality device.
So how much is enough RAM? 4GB.
Whilst a device with 2GB will run the app, you may find the app appears to be running slow, and perhaps will crash unexpectedly - that is what happens when the device cannot handle the amount of
information it is being asked to hold in memory. Go for 4GB RAM and you'll enjoy fast, fluid operation.
There are a few other features you can then look for - but these are not critical - eg. storage - you can go for as little as you like as the internal storage is not that important as you can just use SD card for storage so don't buy based on storage capacity.
You don't have to have a device with a SIM (ie. ability to connect to mobile internet data via 4G) but if you do this is really very handy as it our app has built in features to use the internet for data syncing, downloading updates, and if you wish to use the satellite maps, street maps or online
EOTopo maps. And of course you can then get your emails etc.
Android operating system - just
check that you are getting what you expect when buying new you might assume you are getting the latest version of the OS but this isn't always so. The latest version of android is 11.0 (but not all devices have this yet as its very new, so 10 is ok). I would not accept buying a new device if it doesn't have at least Android 10 however. The reason for this is that the main purpose of the updates is to provide you with the latest security and privacy enhancements to protect you from digital attacks that are constantly being designed by hackers. However, Google (who own Android) also guarantee support for at least two years for all major Android updates, and three years for monthly security updates. After that however, your device is then subject to problems that neither they, no the app developers have any requirement to support.
Hope that helps.
PS don't forget to take a read through the User Manual - its available to anyone before purchase to view/read/download free from the
ExplorOz Traveller webpage (you just need an ExplorOz account - free visitor account is fine, in order to open the file as a standard site security measure).

Thanks for the advice Michelle.
I've been looking around a bit at the Samsung Tabs and saw these but they say they are A7, does that mean the operating system is Android 7?
I can't see anywhere on the add what number the operating system is.

A new Tab A7 runs Android 10 but has 3gB of RAM, not the four that Michelle recommends. I have a new one which I have been running split screen with Ozi Explorer and EOTraveller, but only statically at
home. Unable to travel at the moment apart from suburban running around. Split screen is pretty demanding; however it seems to perform ok. A number of others here have reported good performance with the Tab A7 despite the less than ideal RAM.
I think the hardware in the A7 is pretty good. The compromises to make it cheaper than its more upmarket S series tab competitors is the display, a slower but still capable processor and the lower RAM figure. In reviews the main criticisms are the display and the camera. The display is perfectly adequate for a navigator and general useage but the critics say it is lacking for real graphics work - which is NOT what the A7 is designed for.
Likewise, the camera is perfectly adequate to take a photo for a simple record, such as adding to EO
Places, but is not suitable for detailed digital photography and image manipulation. Again, that is not what the A7's price point is all about.
The A7 is just a good quality utility tablet and doesn't pretend to be more than that.
To get more RAM in a Samsung product you will have to spend considerably more than the asking price for a Tab A7 - AFAIK from my research you will have to step up to the Tab S series where you'll be looking at 1.5 to 3 times the $$$, depending on the model you choose.
There are other brands that may offer 4+gB RAM at the A7 pricepoint but I haven't researched them.

Thanks for your reply Frank.
I've been googling a bit and the S6 Lite 4G 64GB looks like it might go ok?
It has the 4GB ram and looks to be about $120 dearer than the A7
Do you think the sim card is really necessary?
All we will use this for is a navigator so not too worried about camera or screen quality, as long as its adequate for the maps.

I haven't used an S6 Lite, but I'm sure with those specs it would be ok. Depending on how many maps you want to load it up with, you might want to give it an SD card for memory expansion. I use a 128gB card, they're not expensive now. If you want to go overboard with maps, music, eBooks etc to make your tablet do everything in one device you can stick up to 1tB in the SD slot. That's a LOT of data.
I have a lot of maps for Ozi - they all are on the SD card. Also, I install Traveller's maps to the card as
well, leaving internal memory for apps and stuff that is not conveniently put onto the SD card.
I prefer a SIM in my navigator tablet because I want Traveller to do what it's designed to do with as little fuss as possible, but as Michelle says, it's not really necessary - you can hotspot the tablet to your phone. I think a SIM slot will add about $200 to the price - maybe a bit less. And then you have to pay for a data plan - cost dependent on your provider.
Mine is $5 a month with data shared from our mobile plans as part of our bundle.
The display quality will be similar to the A7 and will be fine for maps.
If you wish to contribute photos to EO's
Places, the camera will be fine for that, too, especially in conjunction with Traveller.
