Customer Reviews
the best phone i have ever had. this is a very specific phone and not everyone will like it. but for me it is just 10 out of 10. i am very intensively involved in cycling and running and also really love to go to the mountains and go hiking. so my choice fell on compact phones for a very long time. in my arsenal over the past few years there have been various models of Sony Compact, then the iPhone 12 and 13 mini. these are the most convenient phones for using with one hand while running or intensive cycling, period. And then recently I found out about the Tank mini. At first I was quite skeptical about this phone since it was an unknown brand to me before that caused doubts. but still taking a risk I bought this phone and do not regret it one bit, period I have been using it for more than a month and I have something to tell. firstly, the design and ergonomics: the phone fits perfectly in the hand and is made very well. Secondly, performance and battery: the phone copes very well with all everyday tasks, And about the battery, here is a separate Thanks to the developers. The phone may seem very thick to you But in fact, it just fits perfectly and comfortably in your hand. And its battery is more than enough for two or even 3 days of average intensive use. Regarding the cameras, I will say right away, the cameras are the simplest for the budget segment, nothing surprising. But I did not buy this phone for photo capabilities)). A small digression regarding those who say that the screen is very small and inconvenient to use: You are idiots, remember When the iPhone 5 with a diagonal of 4 inches came out, you all ran and shouted "ugh, what a shovel" ..... Clowns 🤣.... here the screen is 4.3 inches and it is quite comfortable to use, I will not say that it is ideal, since typing text on the keyboard is not particularly easy, But to my surprise, I got used to the phone in just a few days. a few more words about the flashlight, It's winter now and it gets dark very early and the sun rises very late, I run a lot in the mornings and in the evenings and this flashlight is just an amazing thing that I use almost every day, which makes it an integral part of this phone. I was also very pleased that Android 13 is installed here, which is more than enough for all my tasks.I wish your company further development and success in prosperity. If you ever decide to release the next model, I will definitely buy it for myself.
The Tank Mini is an Android 13 phone that has a plethora of features and functions. For the six-month period that it was functional, for me, it was an excellent phone. A fall of about 0.5yards completely killed this phone (rugged?). Little did I know another review posted this exact same problem (see Corentin's review below).
I attempted to warranty replace this phone as it was less than 12-months of ownership, only to be quoted song-and-verse from the Unihertz policy:
"Warranty Exemptions: Damage from outside sources. Damage from misuse of products (including, but not limited to: falls, extreme temperatures, water, operating devices improperly).
Accoring [sic] to our Warranty & Return Policy, your issue is not covered under warranty... Best Regards, ..."
OK, Unihertz can stick to their policy, but this phone has a design defect that needs to be addressed quickly; and, they should consider rapid brand-salvaging and customer-service mitigation because I DO NOT RECOMMEND buying this phone. Caveat emptor.
They made it so you can't organize the apps into folders on the secondary screens. So you are left with a cluttered desktop, which is ridiculous. I hide all but 3 or 4 apps on my phones. Not possible with this.
And it is just too small. Good luck texting or using the keyboard for anything. Perhaps a kid or woman. But someone with average man hands?, not a chance.
And sure it is small across....but it is like an inch thick! So what good does small diameter do if it super thick?
So,overall, it is ok for a kid or woman that doesn't care to organize their apps and is ok with an ungodly thick phone. But otherwise, nope!
