8849 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

Non- - connectivity with cellular network .

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.

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.

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.

Getting used to it. This phone fixes two problems for me: I'm sick of charging my phone everywhere I go - it's on the charger. The TANK goes days - no problem, only falling to 50% after 8 straight hours of screen time. But I still get nervous below 20% when I still have a whole day. Second - I'm always leaving my phone laying around and lose it. The TANK cannot be left behind or tossed into a hidden crack. You can't carry this around in your pocket without a belt holding your pants up. It takes care and time to set this down and pick it up and I do pay attention and hold on with both hands so I don't fall off! I swapped the SIM from my old T-Mobile phone into this one and it took straight off running! No problem, just like the old days. No need to upgrade the memory in this above the 1 TB already on-board, the TANK holds it all. The screen is super clear and bright. The cameras are just OK, if you're used to an Apple or Samsung, you'll hate this part. Focus and zoom work in mysterious ways that contradict what feels normal with a standard Galaxy and I get a bad picture almost every time. But there will be plenty of storage for your badly focused, blurry night vision images. Online, the TANK is a beast, dragging down data faster than T-Mobile allows - above 250 Mb/sec on 5G inside my steel cage. No bloatware with this phone, nada and it's nice. The phone app in Android 14 has never been worse and makes this "phone" seem like a "Want" more than a "Need" when you have to whip it out and use it. Early in on this experience but liking it so far. At this price, I don't expect more than about a year from this anyway. No idea what support can be expected from 8849 when Android 14 gets dusty.

So far I really like this phone. It seems to be pretty stable and fast.

It has an AMOLED display, 3k resolution aka better than quad hd, much more skinny and lighter, laser focus projector rather than the dial and stronger processor. Last a while with it's 11000 mah battery. If you want to play with a actual new phone and not a repeat phone, get this one.
