Top Amazon Reviews
It's finally time to upgrade from my Blu G90 Pro, so my review is in comparison to my old phone running Android 10. Purchased two, so my husband has one as well. I got this mil spec phone more for him because he's always dropping his phone and breaking the screen cover. However it's got features I like as well. I like for us both to have the same model so if there's an issue I can compare the two easily. Things I like: Battery life - lasts all day and I'm a heavy user of apps. Customizable side switch - you can choose three different settings depending on if you push the button once, twice or long press. I have mine set to open Gmail on one click ( with phone unlocked), flashlight with double click which is handy when I need it quickly and it works with the phone locked. USB port and 3mm jack are covered to keep dust and water out. Accessory charging cradle recommended because ports are covered. Cradle is short, so there is room for a pop socket mid back of the phone if you need it. Camera is good, night vision is awesome 😎 Android 14 ROM with minimal bloatware. Some of the preinstalled apps are actually useful especially if you are a maker. Things like camera measuring, protractor and level. There's an attachment connector on the side for other tools as well like a scope sold separately. Rotation is fast with the RAM speed. Overall the phone is very responsive. Bluetooth works well with multiple devices running simultaneously. The meh - Ring light is cool but it doesn't work all the time for me. I might have to play with the settings. Dura speed can suppress apps in the background and if you need notifications from them you need to turn the switch on in dura speed to allow the apps to run normally. It might take trial and error to figure out what apps you need to allow. Volume settings are touchy and it's hard to get the volume just right. The sound is either too quiet or too loud all the time. Sound quality is average. I'd say it sounds like a mid priced Bluetooth speaker. Phone is heavy! But the weight I'm sure is because of the shock protection. I got used to the weight in a couple of days of use. The bad - Not really much to say here and most of the bad is related to Android 14 not the phone. Android 14 settings are a little more difficult to find than in prior versions. I've been an Android user since 2.0 cupcake so I've used almost every release. When swiping sometimes buttons get activated because they are very sensitive. There is a function where I can close all open apps, but without the on screen square close, home and back buttons at the bottom it's hard to find it. I'm not sure how to activate the feature. I've seen it but not sure what I did to make it come up. Somehow Android 14 dropped the link on home screen widget which was a feature I still want. So in all, it's a solid phone. The only thing I wish it had was 5G, but that's ok for now. I don't see 4G going anywhere anytime soon.

Order this Phone for my brother, he loved it. And at the end is all that matters, works like any other Android phone. Good quality, it’s a bit Heavy for my taste, buts not for me. It definitely works for him.

En general con respecto a la resistencia cumple lo que promete, es un telefono de muy buena construccion y se siente fuerte, sin embargo no puedo darle las 5 estrellas porque me ha presentado algunas fallas de conexion a veces pierde señal de telefonia ó se resiste a activar el Bluetooth especialmente cuando se pone en "modo avion" y luego se trata de desactivar este modo a veces se resiste a "volver a la normalidad" y toca reiniciarlo para que funcione correctamente (imagino que es un fallo de software)... siento ademas que las aplicacione extras de software que trae para aprovechar las caracteristicas del telefono son un "poco flojas" y les hace falta para explotar todo el potencial del telefono.. en resumen, como hardware es bueno pero puede mejorar su Software...

Filled with unneeded apps installed as system apps which makes it impossible to uninstall. Only one of the 3 were able to be disabled. Dobest Search cannot be disabled and wants to update via Google Play. Dobest Security was able to be disabled. And Clear Master from Dobest cannot be removed or disabled.

Great battery life can charge my galaxy6 watch night vision camera and ir blaster. The rugged ability keeps me from breaking the phone like I've broken most my other phones.
