- Tank 4 Pro Rugged Smartphone 5G, IP68 Waterproof Android 14 Mobile Cell Phones Unlocked with Projector, 32GB+512GB, 6.73’’ AMOLED Screen, 11600mAh(120W)/1200LM Camping Light/GPS/OTG

I've owned my tank 4 pro for about 3 weeks now, and it is a really nice. For starters, it is running Android 15. Diversion I bought has 18 GB of ram and one terabyte of on-board storage. I put in a 1 TB micro SD card for extra storage. I also turned on the virtual RAM feature, and maxed it out to 18 GB. Virtual ram uses onboard storage to emulate physical ram. The feature I use the most on my tank 4 Pro is its built-in projector. The projector will autofocus whatever image I am displaying through it. I use the projector to watch various YouTube videos when I am not in the same room as my TV. Because there is only one speaker on the phone, and it is located at the bottom rear, if I am not careful I can inadvertently muffle the sound. In terms of battery life, the lowest I have ever been able to drain the phone with regular use is draining the battery to 31%. Binormal use, I am talking about primarily running the projector for a few hours every night on about 90% projector brightness. I can usually get by with not having to plug the tank for Pro into the wall for about three days. Because I do not use the included charger brick that came with the phone, charging takes a little longer for me. While I was able to add the phone to my T-Mobile account, it was not as straightforward as I would have liked. That was not due to an issue with the phone, but with incorrect information I received from T-Mobile support. According to T-Mobile, the tank 4 Pro will only attain 4G speeds on their network. I was ultimately able to add a physical SIM card to the phone. In terms of value for money paid, I personally feel it was a good purchase. I bought my tank 4 Pro as a tablet replacement. The build quality of this phone is excellent in my opinion. It is a solid chunk of a phone. I ended up buying a silicone case for mine, and it looks very nice in the case. I have attached some photos to my review, detailing what the screen looks like as well as the measurements of the phone. UPDATE (about one week before return window closes): The touch screen on the phone has become unresponsive about half the time. This makes using the phone very difficult. As much as I liked using the phone, because of what I paid for it I do not want to run any risk of it failing after the return window closes. I have since filed a return with Amazon, and shipped the phone back.

IT WORK VERY GOOD POWER LESS UP TO 30 HR BUT IT TAKE DIFFICULT TO CONNECTED TO VERIZON THEY SAY IT'S NOT COMPATIBLE.

Let me tell you. I received the Tank 4 Pro. It's an excellent device. I got it in the United States. I installed the T-Mobile chip and it connected immediately without any problems. It's a fast phone, with good colors, it's stable, and it almost never crashes even with several apps open. But it's not for everyone; it's very thick and quite heavy. The Android 14 operating system is quite limited. It's very well made, with top-quality materials. What they show in the promotional videos is true: a lamp that lights up everything and a projector that works very well.

The phone is cool af, don't get me wrong. All of the bells and whistles make it a bad@ss device, however it gets hot FAST. Even under regular use, just watching YouTube, with ZERO additional apps running in the background, it would heat up to where I had to run the internal fan at all times. The sound quality is very good. Cameras are as well. However I had issues establishing straight talks service. It would work for texts and calls but data was unusable and group messaging was not allowed. Straight talk was unable to create a profile for the device, and it ended up not being compatible. It has been returned.

I've had mine for about a day now and so far I really enjoy it! I upgraded from a B2 ultra IIIF150, so weight wasn't a concern. The projector has high quality, the autofocus is great. Screen clarity is good and so far the software is responsive. Plug and Play for T-Mobile as well. Provided that it stays like this long-term, this is an easy recommend.

Phone was great for 3 months until it updated to android 15, now its as useful as a paperweight. Will not connect to data though the phone shows 5g. Tried everything to fix the issue including what a unihertz rep suggested in their Facebook page. Tried reaching out SEVERAL times to unihertz to fix the issue and have not heard a single word back. The product support link here leads to a non working site and their CS email address does not yield any results. Overall, the phone was cool when it worked but now its useless except for a wifi enabled projector. Unihertz has absolute garbage customer support and I do not recommend purchasing any of their products until they get their act together.
